Hedysarum alamutense (Fabaceae-Hedysareae), a new species from Iran, and its phylogenetic position based on molecular data

Abstract

Hedysarum alamutense, a new species in the tribe Hedysareae DC. (Fabaceae), is described and illustrated. It belongs to the traditionally recognized Hedysarum L. section Multicaulia (Boiss.) B.Fedtsch., which extends over the West Alborz Mountains in northern Iran. This species is characterized by greenish stems and corolla persisting in fruiting stage and has mostly 1-2-jointed, unarmed, biconvex pods with short hairs becoming bald early, and flattened margins. Phylogenetic analyses of molecular data clearly unite this species with H. formosum Fisch. & C.A.Mey. ex Basin. The new species is characterized by 4 singleton nucleotide substitutions, suggesting it as a distinct taxon. Phylogenetic inferences are consistent with the interpretations of morphological features. Moreover, the lack of nucleotide variation among individual samples of H. formosum indicated that the species has not been diversified at the population level and reinforced our findings.

New scientific discoveries: Plants and fungi

“…Numerous new species of plant groups used as food for farm animals were published in 2019, predominantly grasses and legumes. Among the legumes were a new species of vetch Vicia brulloi from Sicily (Sciandrello, Del Galdo, Salmeri, & Minissale, 2019), a new grasspea Lathyrus cirpicii from Turkey (Güneş, 2019), and a new sainfoin, Onobrychis garinensis and a new sweetvetch Hedysarum alamutense (Nafisi, Kazempour‐osaloo, Mozaffarian, & Amini‐rad, 2019), both from Iran. New grasses include three new fescues ( Festuca ) from Spain.…”

Chromosome number and meiotic behavior in several plant taxa from iran

“…Fifteen species among them are endemic to Iran. According to recent findings (Ranjbar 2010;Dehshiri & Goodarzi 2016;Nafisi et al 2019), the number of Hedysaum species in Iran has increased to 38, of which 23 are endemic.…”

Use of Sequencing Methods for Species Identification Exemplified by Phylogenetic Relationships Within Genus Hedysarum L.

“…При анализе полученных данных хотелось бы отметить, что наблюдаемая корреляция на примере представителей рода Hedysarum позволяет не только установить степень филогенетического родства различных таксонов [8,9,[40][41][42][43][44][45], но и представить совокупность хемотаксономических признаков, характерных для определенных видов на примере семейства Fabaceae, что в дальнейшем может быть использовано при проведении фармакогностических исследований и разработке нормативной документации на лекарственное растительное сырье.…”
