Homologs of the CYC/TB1 gene family have been independently recruited many times across the eudicots to control aspects of floral symmetry The family Asteraceae exhibits the largest known diversification in this gene paralog family accompanied by a parallel morphological floral richness in its specialized head-like inflorescence. In Asteraceae, whe...

The epicalyx is a structure below the calyx that is often integrated in floral display. In Malvales, the epicalyx is interpreted to be formed by bracts derived from inflorescence reduction. In this study, we compare the epicalyx and flower development of Lavatera trimestris and Malva hispanica, which are close relatives but show contrasting morphol...

Hybridization can generate new species if some degree of isolation prevents gene flow between the hybrids and their progenitors. The recruitment of novel pollinators by hybrids has been hypothesized to be one way in which such reproductive isolation can be achieved. We tested whether pollinators contributed to isolation between two natural Narcissu...

Here we describe a new species from the Brazilian Amazon, Mollia trimera. This species is mainly distinguished from other species of the genus by flowers with trimerous external whorls (calyx, corolla, and outer androecium), a rare morphological characteristic in Malvaceae. Morphological description, taxonomic comments, illustrations, distribution,...

Transcription factors (TFs) regulate gene expression by binding to specific sequences on DNA through their DNA-binding domain (DBD), a universal process. This update conveys information about the diverse roles of TFs, focusing on the NACs (NAM-ATAF-CUC), in regulating target-gene expression and influencing various aspects of plant biology. NAC TFs...

Aim We explore the idea that most pre‐glacial non‐endemic Canarian flora became endemic to the archipelago by the extinction of its mainland populations during the late Pleistocene glaciations, implying that the extant non‐endemic flora is mostly post‐glacial: the ‘late Pleistocene endemicity increase hypothesis’. Taxon The native flora of the Can...

T...

Aim Differentiation of island lineages from mainland relatives and radiation after initial colonization are two important processes generating island diversity. Both of these processes are influenced by colonization dynamics and contemporary connections between island species and their source populations. The classic island progression rule model,...

Navaea phoenicea (Malvaceae) is a flagship shrub species endemic to Tenerife Island in the Canary archipelago and is included as Endangered on the Spanish Red List. We conducted a comprehensive census and monitored the structure of eight accessible populations over 10 years to develop a stage-based demographic matrix model and performed determinist...

A recent study of European annual taxa of Alyssum has revealed that A. simplex includes two cytotypes (diploid and tetraploid) which differ in genetic markers, evolutionary history, and monoploid relative genome size. In this paper we present a new taxonomic treatment of A. simplex in which we treat the two cytotypes as two separate species. We sel...

Canary Islands endemic species that have Mediterranean sister groups constitute suitable systems for addressing classical questions of island biogeography and speciation. This is the case of two polyploid (2n=44) species of plants: Lavatera acerifolia, endemic to the Canary Islands and its sister species Lavatera maritima, distributed along the Wes...

Habitats with alkaline edaphic substrates are often associated with plant speciation and diversification. The tribe Alysseae, in the family Brassicaceae, epitomizes this evolutionary trend.

Introgressive hybridization, as evidenced by topological incongruence between nuclear and mitochondrial phylogenies, has been broadly recorded in a range of organisms. However, mtDNA recombination following hybridization is rarely found in animals and was never until now reported in reef-building corals. Here we report unexpected topological incong...

Despite the importance of the North African region in the complex climatic and geological history of the western Mediterranean basin, the level of sampling of this region in biogeographical and phylogeographical studies is much lower than in the European region. Aiming to contribute to filling this gap, the evolutionary history of Lavatera maritima...

Premise of the study: A bird pollination syndrome exists in the Canary Islands archipelago across independent plant lineages despite the absence of specialist birds. The pollination efficiency of current floral visitors remains unknown for many plant species despite this being a fundamental factor in testing hypotheses about the origin of the synd...

The taxonomic status of Hormathophylla baetica and its phylogenetic relationships to other Hormatophylla species are the subject of controversy. As part of an ongoing study on the genus Hormathophylla, we find that molecular, morphological and biogeographical evidence supports the placement of H. baetica as a subspecies of H. cochleata. We also dis...

Pollinator shifts are considered to drive floral trait evolution, yet little is still known about the modifications of petal epidermal surface at a biogeographic region scale. Here we investigated how independent shifts from insects to passerine birds in the Macaronesian Islands consistently modified this floral trait (i.e. absence of papillate cel...

• Phylogenetic and morphological studies have helped clarify the systematics of large and complex groups such as the tribe Crotoneae (Euphorbiaceae). However, very little is known about the diversity, structure, and function of anatomical features in this tribe. Crotoneae comprises the species-rich pantropical genus Croton and six small neotropical...

Premise of the study: Mountain plants are among the species most vulnerable to global warming, because of their isolation, narrow geographic distribution, and limited geographic range shifts. Stochastic and selective processes can act on the genome, modulating genetic structure and diversity. Fragmentation and historical processes also have a grea...

Background and AimsMost of the diversity in the pseudanthia of Asteraceae is based on the differential symmetry and sexuality of its flowers. In Anacyclus, where there are (1) homogamous capitula, with bisexual, mainly actinomorphic and pentamerous flowers; and (2) heterogamous capitula, with peripheral zygomorphic, trimerous and long-/short-rayed...

Speciation requires the evolution of reproductive barriers to achieve isolation between species. In this paper, we examine the role of two major pre-zygotic barriers in reducing the chance of F1 hybrid formation between two pairs of Narcissus species. Field experiments were performed over 5 years in eight natural populations to determine whether fl...

The genus Alcea (Malvaceae) includes approximately 50 species of mainly Irano-Turanian distribution and is considered one of the most challenging genera of the Middle East, due to its uniformity and pronounced plasticity in morphological traits. Here, using three molecular markers (nrDNA ITS and the plastid spacers psbA-trnH and trnL-trnF), we pres...

1. The evolutionary fate of natural hybridization is determined by the fitness of hybrids. Specifically, the survival of newly formed hybrids is affected by intrinsic genetic incompatibilities and/or genotype–environment interactions. The influence of these factors on the evolutionary potential of two natural hybrids of Narcissus has been assessed....

Although there is evidence that both allopolyploid and homoploid hybridization lead to rapid genomic changes, much less is known about hybrids from parents with different basic numbers without further chromosome doubling. Two natural hybrids, Narcissus × alentejanus (2n = 19) and N. × perezlarae (2n = 29), originated by one progenitor (N. cavanille...

The coastal shrub Armeria pungens has a disjunct Atlantic-Mediterranean distribution. The historic range expansion underlying this distribution was investigated using the nuclear internal transcribed spacer region, three plastid regions (namely trnL-F, trnS-fM and matK) and morphometric data. A highly diverse ancestral lineage was identified in sou...

Insularity in Macaronesia has motivated the existence of a large number of singularities in the evolution of its flora. One the most outstanding phenomena is the occurrence of plants from independent lineages pollinated by generalist passerines, like chiffchaffs or blue tits. The set of plant endemic species –known as the “Macaronesian bird-flower...

Evolutionary consequences of natural hybridization between species may vary so drastically depending on spatial, genetic, and ecological factors that multiple approaches are required to uncover them. To unravel the evolutionary history of a controversial hybrid (Narcissus x perezlarae), here we use four approaches: DNA sequences from five regions (...

The genetic diversity and possible geographic structure of the Madeiran endemic Armeria maderensis have been assessed with AFLP. Its scarce distribution (less than 3km between the two most distant localities) and restricted habitat (vertical pastures on the highest elevations of Madeira), at least in part due to grazing by goats, suggest an assessm...

Low-copy nuclear genes have been suggested as a promising source of independent phylogeographic markers in plants. However, the available studies at the intraspecific level have revealed that extracting information from them is frequently hampered by paralogy and lack of coalescence of alleles. It is thus relevant to test their utility with plants...

The Malva alliance is a well-defined group with extensive morphological homoplasy. As a result, the relationships among the taxa as well as the evolution of morphological traits have remained elusive and the traditional classifications are highly artificial. Using five molecular markers (nuclear ITS, plastid matK plus trnK, ndhF, trnL-trnF, psbA-tr...

Aim The aim of this study was to test hypotheses regarding some of the main phylogeographical patterns proposed for European plants, in particular the locations of glacial refugia, the post‐glacial colonization routes, and genetic affinities between southern (alpine) and northern (boreal) populations. Location The mountains of Europe (Alps, Balkans...

Inferring the evolutionary history of Mediterranean plant lineages from current genetic, distributional and taxonomic patterns is complex because of a number of palaeoclimatic and geological interconnected factors together with landscape heterogeneity and human influence. Therefore, choosing spatially simplified systems as study groups is a suitabl...
