Abstract

A new genus of Zingiberaceae from Vietnam, Newmania N.S. Lý & Škorničk., with two species Newmania serpens N.S. Lý & Škorničk. and N. orthostachys N.S. Lý & Škorničk., is described and illustrated. Its relationship with Haniffia Holttum and phylogenetic position in the tribe Zingibereae is investigated using nrITS and trnK and matK plastid sequence data. The phylogenetic position of Kedhalia C.K. Lim, another recently described ginger genus from the same tribe, is also discussed briefly.

This research aims to identify the volatile compounds from rhizomes and leaves of Newmania sontraensis. The constituents of essential oil from the rhizomes and leaves of N. sontraensis were analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). Thirty-one compounds were identified in the rhizomes compared to the leaves which showed thirty-two volatile compounds corresponding to 83.28 % and 76.41 % of the oil content, respectively. The chemical composition of the rhizome oil was characterized by hydrocarbon monoterpenes accounting for 36.26 %. The major compounds found in the rhizome oil included β-pinene (22.41%), 1,8-cineole (8.32 %), bicyclogermacrene (6.94 %), α-terpinyl acetate (5.74 %), α-pinene (5.71 %), and camphene (5.58 %). Meanwhile, sesquiterpene hydrocarbons were the main compounds found in the leaf oil accounting for 54.18 %. Bicyclogermacrene (14.60 %), δ-elemene (9.89 %), β-elemene (7.26 %), and α-terpinyl acetate (4.27 %) were determined to be the main components found in leaf oil. This was the first report on the chemical constituents of essential oils from rhizomes and leaves of N. sontraensis.

... While this preliminary study was useful in documenting this distinguishing character between the two subfamilies, it only documented four characters for the 60 taxa analyzed. Th is is true for many previous studies on Zingiberales seeds where very few seed characters are incorporated into analyses, which limits their application in plant TABLE 1. Currently recognized subfamilies, tribes, and genera within Zingiberaceae (after Kress et al., 2002 ;Takano and Nagamasu, 2007 ;Leong-Škorničková et al., 2011 ;Mood et al., 2014 ).

Premise of the study: Recent phylogenetic analyses based on molecular data suggested that the monocot family Zingiberaceae be separated into four subfamilies and four tribes. Robust morphological characters to support these clades are lacking. Seeds were analyzed in a phylogenetic context to test independently the circumscription of clades and to better understand evolution of seed characters within Zingiberaceae. Methods: Seventy-five species from three of the four subfamilies were analyzed using synchrotron based x-ray tomographic microscopy (SRXTM) and scored for 39 morphoanatomical characters. Key results: Zingiberaceae seeds are some of the most structurally complex seeds in angiosperms. No single seed character was found to distinguish each subfamily, but combinations of characters were found to differentiate between the subfamilies. Recognition of the tribes based on seeds was possible for Globbeae, but not for Alpinieae, Riedelieae, or Zingibereae, due to considerable variation. Conclusions: SRXTM is an excellent, nondestructive tool to capture morphoanatomical variation of seeds and allows for the study of taxa with limited material available. Alpinioideae, Siphonochiloideae, Tamijioideae, and Zingiberoideae are well supported based on both molecular and morphological data, including multiple seed characters. Globbeae are well supported as a distinctive tribe within the Zingiberoideae, but no other tribe could be differentiated using seeds due to considerable homoplasy when compared with currently accepted relationships based on molecular data. Novel seed characters suggest tribal affinities for two currently unplaced Zingiberaceae taxa: Siliquamomum may be related to Riedelieae and Monolophus to Zingibereae, but further work is needed before formal revision of the family.
... The mountainous areas of Quảng Ngãi Province, which is located in the South Central coastal region of Vietnam on the eastern slope of the Truong Son Range (Dãy Trường Sơn or Annamite Range), have been the scene of many recent discoveries of endemic species and genera in families such as Annonaceae, Araceae, Arecaceae, Asparagaceae, Begoniaceae, Fagaceae and Zingiberaceae (e.g. Leong-Škorničková et al. 2011, Henderson and Nguyễn 2019, Lý 2016, 2017, Lý and Tillich 2016. ...

A genus and species of palm from the Truong Son Range in Vietnam, Truongsonia lecongkietii, is described as new to science. Phylogenomic analysis strongly supports the placement of the new taxon in subfamily Arecoideae as sister to the African endemic tribe Podococceae, which comprises a single genus Podococcus. A new tribe Truongsonieae is also described to accommodate Truongsonia in the current phylogenetic classification of palms. Truongsonia is a dwarf, acaulescent, clump-forming palm bearing entire, bifid leaves with a fibre-like extension of the rachis through the sinus of the two lobes of the leaf. The interfoliar inflorescence is exserted on a long peduncle with 3­–4 tightly sheathing peduncular bracts and rachillae presented at the apex only. The ovary is triovulate-tricarpellate, but fruits are single-seeded. Truongsonia is Critically Endangered, with surveys locating only 10–15 plants in the wild. Swift conservation action is required to secure the future of this remarkable and phylogenetically isolated lineage of palms.

Zingibereae is a large tribe in the family Zingiberaceae, which contains plants with important medicinal, edible, and ornamental values. Although tribes of Zingiberaceae are well circumscribed, the circumscription of many genera within Zingibereae and the relationships among them remain elusive, especially for the genera of Boesenbergia, Curcuma, Kaempferia and Pyrgophyllum. In this study, we investigated the plastome variation in nine species representing five genera of Zingibereae. All plastomes showed a typical quadripartite structure with lengths ranging from 162,042 bp to 163,539 bp and contained 132–134 genes, consisting of 86–88 coding genes, 38 transfer RNA genes and eight ribosomal RNA genes. Moreover, the characteristics of the long repeats sequences and simple sequence repeats (SSRs) were detected. In addition, we conducted phylogenomic analyses of the Zingibereae and related taxa with plastomes data from additional 32 species from Genbank. Our results confirmed that Stahlianthus is closely related to Curcuma, supporting the idea of merging it into Curcuma. Kaempferia, Boesenbergia and Zingiber were confirmed as close relatives and grouped together as the Kaempferia group. Pyrgophyllum is not allied with the Curcuma clade but instead is embedded within the Hedychium clade. Our results demonstrate the power of plastid phylogenomics in improving the phylogenetic relationships within Zingibereae and provide a new insight into plastome evolution in Zingibereceae.

In the present paper, the genus Scaphochlamys from Borneo is revised. Twenty-four species are recognised, of which 11 are new species: S. durga, S. graveolens, S. hasta, S. lanjakensis, S. lucens, S. nigra, S. multifolia, S. penyamar, S. pseudoreti-cosa, S. scintillans, and S. uniflora. Scaphochlamys depressa is treated as a synonym to S. argentea. The Bornean species are arranged into six informal groups based on morphological characteristics: Anomala Group, Calcicola Group, Graveolens Group, Limiana Group, Petiolata Group, and Polyphylla Group. The paper includes an overview of morphological characteristics , identification keys to groups and species, and species descriptions. A discussion of the recently recognized generic segregate, Borneocola is included.
... As a result of extensive field exploration and collection of Zingiberales in Vietnam since 2008, numerous novelties, including a new genus, have already been described (e.g. Leong-Škorničková & Lý, 2010;Leong-Škorničková et al., , 2011Leong-Škorničková et al., , 2015aLeong-Škorničková et al., , 2015bLeong-Škorničková & Lưu, 2013;Leong-Škorničková & Trần, 2013).

A new genus from Borneo, Borneocola Y.Y.Sam, is described here. The genus currently contains eight species previously classified as members of the Scaphochlamys Baker. The finding is based on the results of the morphological and molecular studies of Scaphochlamys throughout its geographical range and its closely allied sister groups, Distichochlamys M.F.Newman and Myxochlamys A.Takano & Nagam. Borneocola is nested within the tribe Zingibereae and its monophyly is strongly supported by both ITS and matK sequence data. The genus is characterised by several thin, translucent and marcescent floral bracts, absence of coloured streaks on the labellum and capitate stigma with two dorsal knobs. The genus is distributed in northwest Borneo and all species are very rare and highly endemic.

The current study describes chemical compositions and antimicrobial activity of essential oils from the rhizome of two Vietnamese ginger plants Newmania orthostachys N.S. Lý & Škorničk. and Newmania serpens N.S. Lý & Škorničk. 49 compounds (98.4%) were identified in N. orthostachys rhizome oil, whereas 54 compounds (93.4%) were identified in N. serpens rhizome oil. N. orthostachys rhizome essential oil was dominated by monoterpene hydrocarbons (74.2%), in which β-pinene (35.7%), α-pinene (13.4%), sabinene (8.0%), camphene (6.7%), and limonene (5.1%) were characteristic compounds. Monoterpene hydrocarbons (33.5%) and sesquiterpene hydrocarbons (44.1%) represented N. serpens rhizome essential oil, as well as β-pinene (18.5%), bicyclogermacrene (12.4%), β-selinene (8.2%) were the principal compounds. In an antimicrobial assay against three tested Gram-positive bacteria Enterococcus faecalis ATCC 29212, Staphylococcus aureus ATCC 25923, and Bacillus cereus ATCC 14579, both two essential oils showed the minimum inhibitory concentration (MIC) values of 16-64 µg/mL lower than those of positive control Streptomycin (MIC 128-256 µg/ml). These two essential oils with the MIC values of 8-16 µg/mL are also better than the positive control cycloheximide (MIC 32 µg/mL) against the yeast Candida albicans ATCC 10231.

Lithocarpus cadamensis Ngoc & Son, a new species of Fagaceae, is described and illustrated from Mt. Ca Dam, Tra Bong District, Quang Ngai Province, central Vietnam. The new species is characterized by its large leaf blades with long petioles, solitary and subsessile cupules which almost completely cover the nut, and spiny cupule scales, in a combination that clearly differs from the previously known species of Lithocarpus including the most similar species in the region, L. campylolepis, L. eucalyptifolius, and L. gougerotae. A MIG-seq phylogeny based on genome-wide SNPs reveals a phylogenetic position close to L. eucalyptifolius, from which the new species is differentiated by multiple morphological characters. A morphological description and comparison with related species, photographs, line drawing, preliminary conservation status, and DNA barcode sequences are provided for the new species.

In 1909, Ridley published Adelmeria characterized by its congested terminal inflorescence with large persistent floral bracts. All five species at some point placed in Adelmeria were synonymized in Alpinia by Loesener and subsequent authors. Several phylogenetic studies revealed that Alpinia is highly polyphyletic, suggesting that it should be split into several genera. In the present study, we sampled all five species initially placed in Adelmeria plus additional ones with a similar morphology. The combined analysis of the ITS and trnK/matK regions showed that these species formed a strongly supported monophyletic group inside the Alpinia eubractea clade of the tribe Alpinieae. Although not completely diagnostic, the following morphological characters separate Adelmeria from most of the species currently inside the Alpinia eubractea clade: bilobed ligules; congested inflorescences; utricular bracteoles; sessile flowers; crestless anthers; obovoid fruits. Considering this molecular and morphological evidence, the recognition of Adelmeria is highly justified. In this present paper, we reinstate the genus which is endemic to the Philippines and provide a comprehensive taxonomic revision including a discussion of the application of the name Elmeria. A key to nine species of Adelmeria, four of which (A. dicranochila, A. isarogensis, A. leonardoi, A. undulata) are new to science, is provided as well as full descriptions and preliminary conservation assessments. Interestingly, monoecy was observed in A. oblonga and reported for the first time for Adelmeria. Four lectotypes and one epitype are designated in this study.

The genus Vanoverberghia currently includes three species namely V. sepulchrei and V. rubrobracteata from the Philippines and V. sasakiana from Taiwan. New material targeting the Alpinia eubractea clade of the tribe Alpinieae was used to test the monophyly of Vanoverberghia. A combined analysis of the ITS and trnK/matK regions reveals that these three species form a strongly supported monophyletic clade with Alpinia diversifolia and Alpinia vanoverberghii. The morphological descriptions of all species were updated after examining recent collections and comparing with types and protologues. The original description of A. diversifolia did not include information on the flowers which are described here. The morphology of A. diversifolia and A. vanoverberghii is for most parts in accordance with the previous perception of the genus but a few characters are added and a recircumscription of Vanoverberghia is subsequently provided here. Vanoverberghia diversifolia is reinstated and A. vanoverberghii is combined in Vanoverberghia. Furthermore, collections from northern Luzon documents the presence of V. sasakiana and all species of Vanoverberghia thus occur in the Philippines. A key to the five species is provided including a comprehensive taxonomic revision and designation of three lectotypes.

A new species of Begonia ( B. lecongkietii N.S.Lý & M.Hughes) is described from Mount Dầu in the South Central Coast Region, Vietnam, an area with an abundance of recently described endemic plant taxa. The new species is allied to Begonia lamxayana Souvann., which occurs 600 km away in Laos, differing chiefly in having larger villose tepals with an undulate margin and larger androecium with 86–116 (versus 20–30) stamens. Begonia lecongkietii is considered Critically Endangered, owing to its small area of occupancy and decline of habitat quality.

Phenotypic variation can be attributed to genetic heritability as well as biotic and abiotic factors. Across Zingiberales, there is a high variation in the number of species per clade and in phenotypic diversity. Factors contributing to this phenotypic variation have never been studied in a phylogenetic or ecological context. Seeds of 166 species from all eight families in Zingiberales were analyzed for 51 characters using synchrotron based 3D X-ray tomographic microscopy to determine phylogenetically informative characters and to understand the distribution of morphological disparity within the order. All families are distinguishable based on seed characters. Non-metric multidimensional scaling analyses show Zingiberaceae occupy the largest seed morphospace relative to the other families, and environmental analyses demonstrate that Zingiberaceae inhabit both temperate and tropical regions, while other Zingiberales are almost exclusively tropical. Temperate species do not cluster in morphospace nor do they share a common suite of character states. This suggests that the diversity seen is not driven by adaptation to temperate niches; rather, the morphological disparity seen likely reflects an underlying genetic plasticity that allowed Zingiberaceae to repeatedly colonize temperate environments. The notable morphoanatomical variety in Zingiberaceae seeds may account for their extraordinary ecological success and high species diversity as compared to other Zingiberales.

The history of Boesenbergia longiflora (Wall.) Kuntze (Zingiberaceae) is reviewed, its identity is discussed and a lectotype designated. Five new, related taxa are described and illustrated: B. collinsii Mood & L.M.Prince, B. hamiltonii Mood, S.Dey & L.M.Prince, B. kerrii Mood, L.M.Prince & Triboun, B. kingii Mood & L.M.Prince, and B. maxwellii Mood, L.M.Prince & Triboun. A phylogenetic analysis of plastid trnK intron (including matK) and nuclear ITS DNA sequence data indicate these Boesenbergia species form a clade within Boesenbergia. Results of the molecular data analyses in concert with several diagnostic characters, support the recognition of the new taxa. Historical illustrations, colour plates, a field key to the species, a comparative table, a listing of the botanical history of B. longiflora, and a geographical distribution map are provided.

Nucleotide sequences of the plastid encoded gene matK were examined for their potential utility in phylogenetic analyses within angiosperm families. Sequences 661 bases in length were obtained from twenty species of Polemoniaceae. Phylogenetic analyses resulted in four equally parsimonious trees with a consistency index of 0.70. Several well supported groups allowed us to test hypotheses of relationship within Polemoniaceae. The segregation of Ipomopsis and Allophyllum from Gilia was supported by the placement of each in distinct groups separate from a group of four species of Gilia. Several strongly supported groups include genera now placed in different tribes. There was no support for the current separation of temperate Polemoniaceae into two tribes. The tropical genera were resolved as basal and paraphyletic within the family. The family as a whole was monophyletic with no support for the segregate family Cobaeaceae. Sequences of matK, a gene that had not been used previously for phylogenetic analyses, provided a sufficient number of reliable characters for phylogenetic analysis within Polemoniaceae. Pairwise comparisons of matK and rbcL sequences of the same taxa were performed. Sequences of matK varied at an overall rate twice that of rbcL sequences. Substitutions at the third codon position predominated in rbcL sequences, while in matK substitutions were more evenly distributed across codon positions.

Larsenianthus W. J. Kress & Mood, gen. nov. is described with one new combination and three new species. Larsenianthus careyanus (Benth.) W. J. Kress & Mood, comb. nov., is widespread in India and present-day Bangladesh; Larsenianthus wardianus W. J. Kress, Thet Htun & Bordelon, sp. nov., is from upper Myanmar in Kachin State; Larsenianthus assamensis S. Dey, Mood, & S. Choudhury, sp. nov., is restricted to Assam, India; and Larsenianthus arunachalensis M. Sabu, Sanoj & T.Rajesh Kumar, sp. nov., has only been found in Arunachal Pradesh, India. A phylogenetic analysis using the plastid trnK intron and nuclear ITS DNA sequence data indicates that the four species of Larsenianthus form a monophyletic lineage that is sister to Hedychium, a geographically widespread genus of about 50 species in tribe Zingibereae of subfamily Zingiberoideae. A dichotomous key and three-locus DNA barcodes are provided as aids for the identification of the four species of Larsenianthus.

Phylogenetic relationships were examined within the "higher" Hamamelididae using 21 species representing eight families and related outgroups. Chloroplast DNA sequences encoding the matK gene (/1 kilobase) provided 258 informative nucleotide sites. Phylogenetic analysis of this variation produced one most parsimonious tree supporting three monophyletic groups. In this tree, Nothofagus was basal to a well supported clade of remaining "higher" hamamelids, in which Fagaceae, including Fagus, were sister to a clade of core "higher" hamamelids that share wind-pollination, bicarpellate flowers, granular pollen walls, and reduced pollen apertures. Within the core "higher" hamamelids three subclades were resolved, Myricaceae, (Casuarina-(Ticodendron-(Betulaceae))), and (Rhoiptelea-Juglandaceae). Each subclade was well supported but relationships among them were not. The basal position of Nothofagus within the matK tree is consistent with the fossil record of "higher" hamamelids in which Nothofagus pollen appears earlier than microfossils with affinities to other modern "higher" hamamelids. This placement supports the exclusion of Nothofagus from Fagaceae and suggests two hypotheses for the origin of the cupule. The cupule may be ancestral within "higher" hamamelids and subsequently lost in core members of the clade or there may have been two independent origins. It is suggested that the three clades (1) Nothofagaceae, (2) Fagaceae, and (3) Juglandaceae, Rhoiptelea, Myricaceae, Casuarina, Ticodendron, and Betulaceae be considered at the ordinal level and that traditional orders, such as Fagales sensu Cronquist (Fagaceae, Nothofagaceae, and Betulaceae) be abandoned. Comparative analyses of matK sequences with previously published rbcL sequences demonstrate that for the taxa considered here matK sequences produced trees with greater phylogenetic resolution and a higher consistency index.

The pantropical Zingiberaceae is the largest family in the order Zingiberales with 53 genera and over 1200 species. Classifications of the family first proposed in 1889 and refined by others since that time recognize four tribes (Globbeae, Hedychieae, Alpinieae, and Zingibereae) based on morphological features, such as number of locules and placentation in the ovary, development of staminodia, modifications of the fertile anther, and rhizome-shoot-leaf orientation. New phylogenetic analyses based on DNA sequences of the nuclear internal transcribed spacer (ITS) and plastid matK regions suggest that at least some of these morphological traits are homoplasious and three of the tribes are paraphyletic. The African genus Siphonochilus and Bornean genus Tamijia are basal clades. The former Alpinieae and Hedychieae for the most part are monophyletic taxa with the Globbeae and Zingibereae included within the latter. The results of these phylogenetic investigations are used to propose a new classification of the Zingiberaceae that recognizes four subfamilies and four tribes: Siphonochiloideae (Siphonochileae), Tamijioideae (Tamijieae), Alpinioideae (Alpinieae, Riedelieae), and Zingiberoideae (Zingibereae, Globbeae). Morphological features congruent with this classification and the taxonomic status of various monotypic genera are discussed.

Smithatris supraneanae W. J. Kress & K. Larsen, gen. et sp. nov. is described and illustrated. The new taxon was first collected in the limestone hills in the Saraburi Province north of Bangkok, Thailand, and probably ranges into adjacent Burma as well. Smithatris is most closely allied with several genera in the tribe Hedychieae including Curcuma, Stahlianthus, and Hitchenia. It most closely resembles the latter genus sharing the petiolate leaves and long pedunculate inflorescence with congested, pouched bracts, but differing in the deeply split labellum and hood-like structure formed by the lateral staminodes and dorsal corolla lobe that partially encloses the anther. In a separate analysis of the phylogenetic relationships of the genera of the Zingiberaceae based on molecular sequence data, Smithatris forms a nested assemblage with the above three genera thereby supporting recognition of this new taxon at the generic level. Smithatris is commonly used in ceremonies during the Buddhist lent, is sold as a cut flower in local markets in Saraburi, Thailand, and recently has become widespread in commercial nurseries. The fact that this ethnobotanically important plant has remained unknown to taxonomists until now suggests that our knowledge of the flora of tropical Asia is still rudimentary.

— We studied sequence variation in 16S rDNA in 204 individuals from 37 populations of the land snail Candidula unifasciata (Poiret 1801) across the core species range in France, Switzerland, and Germany. Phylogeographic, nested clade, and coalescence analyses were used to elucidate the species evolutionary history. The study revealed the presence of two major evolutionary lineages that evolved in separate refuges in southeast France as result of previous fragmentation during the Pleistocene. Applying a recent extension of the nested clade analysis (Templeton 2001), we inferred that range expansions along river valleys in independent corridors to the north led eventually to a secondary contact zone of the major clades around the Geneva Basin. There is evidence supporting the idea that the formation of the secondary contact zone and the colonization of Germany might be postglacial events. The phylogeographic history inferred for C. unifasciata differs from general biogeographic patterns of postglacial colonization previously identified for other taxa, and it might represent a common model for species with restricted dispersal.

The phylogenetic relationships of the genus Sorghum and related genera were studied by sequencing the nuclear ribosomal DNA (rDNA) internal transcribed spacer region (ITS). DNA was extracted from 15 Sorghum accessions, including one accession from each of the sections Chaetosorghum and Heterosorghum, four accessions from Parasorghum, two accessions from Stiposorghum, and seven representatives from three species of the section Sorghum (one accession from each of S. propinquum and S. halepense, and five races of S. bicolor). The maize (Zea mays) line, H95, and an accession from Cleistachne sorghoides were also included in the study. Variable nucleotides were used to construct a strict consensus phylogenetic tree. The analyses indicate that S. propinquum, S. halepense and S. bicolor subsp. arundinaceum race aethiopicum may be the closest wild relatives of cultivated sorghum; Sorghum nitidum may be the closest 2n=10 relative to S. bicolor, the sections Chaetosorghum and Heterosorghum appear closely related to each other and more closely related to the section Sorghum than Parasorghum; and the section Parasorghum is not monophyletic. The results also indicate that the genus Sorghum is a very ancient and diverse group.

The importance and abundance of cryptic species among invertebrate taxa is well documented. Nowadays, taxonomic, phylogenetic and conservation biological studies frequently use molecular markers to delineate cryptic taxa. Such studies, however, often face the problem of the differential resolution of the molecular markers and techniques involved. This issue is explored in the present study of cryptic taxa within the terrestrial slug complex Arion subfuscus/fuscus in continental north-west Europe. To this end, morphological, allozyme and mitochondrial 16S rDNA sequence data have been jointly evaluated. Using allozyme data and gonad type, two distinct groups were consistently delineated, even under sympatric conditions. The 16S rDNA data strongly supported both those groups and even suggested the presence of three distinct taxa within one of them. However, in view of: (1) the allopatric distribution of three OTUs, (2) the lack of allozyme or morphological differentiation, and (3) the extremely high degree of intraspecific mtDNA variation reported in pulmonate gastropods, they are, for the time being, not regarded as valid species under the biological species concept. By means of 16S rDNA and allozyme data, the position of type and topotype material of A. subfuscus s.s. and A. fuscus relative to the newly defined OTUs was determined, thus clarifying the nomenclature of this species complex. Additionally, gonad type proved to be a useful character for distinguishing the two species in north-west Europe. © 2004 The Linnean Society of London, Biological Journal of the Linnean Society, 2004, 83, 23–38.

Comparative studies of the relationship between 2 phenotypes, or between a phenotype and an environment, are frequently carried out by invalid statistical methods. Most regression, correlation, and contingency table methods, including nonparametric methods, assume that the points are drawn independently from a common distribution. When species are taken from a branching phylogeny, they are manifestly nonindependent. Use of a statistical method that assumes independence will cause overstatement of the significance in hypothesis tests. Some illustrative examples of these phenomena are given, and limitations of previous proposals of ways to correct for the nonindependence discussed. A method of correcting for the phylogeny is proposed. It requires that we know both the tree topology and the branch lengths, and that we be willing to allow the characters to be modeled by Brownian motion on a linear scale. Given these conditions, the phylogeny specifies a set of contrasts among species, contrasts that are statistically independent and can be used in regression or correlation studies. -from Author

We describe MUSCLE, a new computer program for creating multiple alignments of protein sequences. Elements of the algorithm include fast distance estimation using kmer counting, progressive alignment using a new profile function we call the log‐expectation score, and refinement using tree‐dependent restricted partitioning. The speed and accuracy of MUSCLE are compared with T‐Coffee, MAFFT and CLUSTALW on four test sets of reference alignments: BAliBASE, SABmark, SMART and a new benchmark, PREFAB. MUSCLE achieves the highest, or joint highest, rank in accuracy on each of these sets. Without refinement, MUSCLE achieves average accuracy statistically indistinguishable from T‐Coffee and MAFFT, and is the fastest of the tested methods for large numbers of sequences, aligning 5000 sequences of average length 350 in 7 min on a current desktop computer. The MUSCLE program, source code and PREFAB test data are freely available at http://www.drive5. com/muscle.
