Cistanche deserticola Ma is illustrated and described. This species is native to China where it has long been valued and used in Traditional Chinese Medicine and is now cultivated extensively for trade. The species is confused easily with closely related species such as Cistanche salsa (C.A. Mey.) Beck. Bract and vascular bundle morphology, and hab...

‘Desert hyacinths’ (Cistanche) are a remarkable genus of parasitic plants, some of which are traded widely for herbal medicine or have historical local importance as food. Despite their importance, little or nothing is known about the biology of most species and their taxonomy remains confused, hindering identification. A growing body of research i...
Article
Understanding how species diversify and evolve in species-rich areas like the lowland rain forest in the Neotropics is critical for conservation in times of unprecedented threats. To determine how the Andean uplift, the formation of the Panama land bridge, and Pleistocene climatic fluctuations affected dispersal and diversification in the Sapotacea...

Leguminosae, Polygalaceae, Quillajaceae and Surianaceae together comprise the order Fabales. Phylogenetic relationships within Fabales remain an unsolved problem even though interfamilial relationships have been examined in a number of studies using different sampling approaches and both molecular and morphological data. In this study, we gather in...

Fabales is a cosmopolitan angiosperm order which consists of four families, Leguminosae (Fabaceae), Polygalaceae, Surianaceae and Quillajaceae. Despite the great interest in this group, a convincing phylogeny of the order is still not available. Therefore, the aim of the current study is to explicitly test for possible LBA problems within Fabales f...

Ethnobotanical databases serve as repositories of traditional knowledge (TK), either at international or local scales. By documenting plant species with traditional use, and most importantly, the applications and modes of use of such species, ethnobotanical databases play a role in the conservation of TK and also provide access to information that...

DNA barcoding of herbal medicines has been mainly concerned with authentication of products in trade and has raised awareness of species substitution and adulteration. More recently DNA barcodes have been included in pharmacopoeias, providing tools for regulatory purposes. The commonly used DNA barcoding regions in plants often fail to resolve iden...
Article
Human life depends on plant biodiversity and the ways in which plants are used are culturally determined. Whilst anthropologists have used phylogenetic comparative methods (PCMs) to gain an increasingly sophisticated understanding of the evolution of political, religious, social and material culture, plant use has been almost entirely neglected. Me...
Article
Objective The Chinese Pharmacopoeia (2015) includes 584 plant medicines, of which 284 also contain high quality subsets, so called “Daodi” components, where Daodi denotes superior clinical properties compared to non-Daodi counterparts despite being sourced from the same species. Commercial and clinical drivers of selection for Daodi have been descr...

Plants are important resources in healthcare and for producing pharmaceutical drugs. Pharmacological and phytochemical characterization contributes to both the safe use of herbal medicines and the identification of leads for drug development. However, there is no recent assessment of the proportion of plants used in ethnomedicine that are character...

... The data presented in this paper is supporting the research article "Reconstructing an historical pollination syndrome: keel flowers" (Aygören Uluer et al., 2022). We present a dataset containing information on number of species, geographic distribution, floral type (keeled or not), presence or absence of fused petals, floral symmetry, presence or absence of a pentamerous corolla (petals + petaloid sepals in Polygalaceae), androecium type, presence or absence of enclosed reproductive organs, presence or absence of three distinct petal types (petals + petaloid sepals in Polygalaceae), flower size, corolla size (i.e., in open flower) and/or filament size (i.e., entire filament size particularly in subfamily Caesalpinioideae), flower colour, UV reflectance, habit, height, inflorescence type and inflorescence size for 758 Fabales genera. ...
... Some evidence suggests traditionally important crops such as fruits and berries may be more resilient to effects of increased CO 2 exposure, still, salinity and drought exposure were still found to be important factors reducing yield (Alae-Carew et al., 2020). A recent study suggests that these underutilized species may be a reservoir for micronutrients in a changing world (Cantwell-Jones et al., 2022). Ma'afala is the first widely available commercial variety of breadfruit with estimates now being that about 100,000 trees have been distributed globally. ...
... Previous studies suggested that the plant mitochondrial electron-transport chain could improve plant performance under stressful environmental conditions [29]. Unlike C. deserticola and C. salsa, C. tubulosa experience salt stress and cold stress rather than drought stress [30][31][32]. This might lead to the duplication of genes in C. tubulosa. ...
... The closure of the portal could have seeded both, the process of isolation between Western and Eastern T. guianensis, and the vicariance within the Azteca clade AE (Fig. 3). The same locations of low height are also associated with ongoing trans-cordilleran gene flow in Gasteracantha spiders (Salgado-Roa et al., 2018) and several plant lineages, including Neotropical orchids (Pérez-Escobar et al., 2017), Ficus insipida populations (Honorio Coronado et al., 2014), Theobroma and Herrania (Richardson et al., 2015) and Sapotaceae (Serrano et al., 2021). It is possible that the Andean uplift was not the only event contributing to isolate populations across the cordillera. ...
... Over the past decade, growth in the availability of genetic data for plants coupled with development of software for comparative phylogenetic analysis has facilitated a more comprehensive and detailed understanding of how medicinal plant species are distributed across the plant Tree of Life (Reviewed in [369]). Numerous studies confirm the earlier inferences of ethnobotanists that, far from being randomly distributed, plants used for medicine are strongly clustered on the Tree of Life [9]. ...
... To determine whether the first-evolving Polygalaceae keel flowers were functionally similar to existing Papilionoideae keel flowers, and might have evolved in an environment where functionally similar Papilionoideae keel flowers were present, we carried out temporal, spatial and trait analyses. The divergence-time analysis was congruent with previous studies (e.g., [12,39]), with short internal branches of Fabales reflecting the rapid radiation already highlighted for this clade [12,48,49]. The divergence-time analysis also showed that keel flowers in crown Papilionoideae Our ancestral area reconstructions show that at the time keel flowers appeared in the Polygaleae, the Papilionoideae was distributed almost globally. ...

... Furthermore, in the plastome tree (Fig. 7A), the relationships among most clades are well resolved (PP = 1.00) implying the great power of using complete plastomes to address intractable phylogenetic relationships. Plastid phylogenomics of the family Berberidaceae [16] and of its different subordinate taxa have been studied in depth, including Podophylloideae [35], Epimedium [6], Berberis and Mahonia [2,50]. Given the phylogeny topologies with strong support values, these results demonstrated the power of plastid phylogenomics for improving plastome-based phylogeny, investigating early-divergent events, and conducting taxonomic and plastome evolution analyses. ...
... GWAS studies on adaptive genotypic and phenotypic variation provide a framework to assess the diversity of medicinal plant application across different cultures and infer modifications in plant use over time. 70,71 Other genomic approaches such as genomic selection, nested association mapping, genetic diversity, and allele mining have been integrated into crop improvement programs to address the genetic issues associated with maize productivity and nutritional contents. 72 Plant omics studies have greatly helped our understanding and interpretation of plant responses to ecological influences and their contribution to key developmental processes important for crop yield and food quality. ...
