“…This was previously noted by us in the case of H. sunhangii Juram. & Tojibaev and H. nuratense Popov (Juramurodov & al., 2021a), suggesting explosive speciation as a possible explanation. When many speciation events occur in a short period of time, species may not differ sufficiently in their DNA sequences.…”

“…The botanical exploration of Hedysarum in Central Asia has a history of more than 150 years (Juramurodov & al., 2021a). The first significant studies of the genus in the region were carried out by Baitenov (1964), who investigated the evolution of the genus based on morphology and also described more than 10 new species (Baitenov, 1956(Baitenov, , 1961(Baitenov, , 1964.…”

Central Asia, especially the Tian‐Shan and Pamir‐Alay, is a biodiversity hotspot for Hedysarum (Fabaceae) with a high number of endemic species. However, to date, studies of the genus Hedysarum based on molecular data have included only a few species distributed in this region. To fill this gap, we analysed 110 Hedysarum species, 36 of which were from the Tian‐Shan and Pamir‐Alay Mountains of Central Asia. We performed phylogenetic analyses, divergence time estimates, and biogeographic analyses using both the internal transcribed spacers of nuclear ribosomal DNA (nrDNA ITS) and three plastid DNA (cpDNA) sequences (trnL‐trnF, matK, psbA‐trnH). Our phylogenetic analysis grouped the species of Hedysarum into three sections: H. sect. Hedysarum, sect. Multicaulia, and sect. Stracheya, which are largely consistent with previous phylogenetic classifications. Accordingly, most of the Central Asian species we studied (28 spp.) were placed in H. subsect. Crinifera within H. sect. Multicaulia. Our divergence time and biogeographic analyses indicate that Hedysarum likely originated in West Asia and/or East Asia during the Early Miocene or Middle Miocene and subsequently dispersed to adjacent areas of Eurasia, as well as North America via the Bering Land Bridge. The likely area of origin for H. sect. Multicaulia is West Asia, while East Asia appears to be the center of origin for H. sect. Hedysarum and sect. Stracheya. In addition, we suggest that the rapid radiation of the species of H. subsect. Crinifera occurred in the Tian‐Shan and Pamir‐Alay Mountains, as well as the Turkish‐Iranian Plateau, and that geological and climatic changes were the main causes of speciation in Hedysarum.

“…Lots of new Hedysarum species were described from the European part of Russia, Iran and China (Pjak & Ebel 2000, Sa 2007, Ranjbar et al 2008, Knyasev 2011, Dehshiri & Good ar zi 2016. In addition to ecomorphological features and geographic area, some authors provide molecular data supporting the status of newly described species (Liu et al 2017a, Nafisi et al 2019, Juramurodov et al 2021.…”

Over 2000 specimens of the genus Hedysarum L., belonging to 48 species and 4 subspecies, were digitised and placed into CSBG SB RAS Digital herbarium whilst making a digital inventory of the herbarium collections of the Central Siberian Botanical Garden (NS, NSK). Totally, 466 nucleotide sequences were determined for 136 voucher specimens using the Sanger sequencing method. DNA sequences were obtained for 25 Hedysarum taxa for the first time.

The flora of Uzbekistan is characterized by a high diversity of Lamiaceae and has about 240 species belonging to 40 genera. 30 species of the family Lamiaceae are listed in the Red Book. Rare species require regular monitoring and comprehensive study, both by classical methods and by methods of molecular genetic analysis. This study is aimed at assessment the species diversity of the flora of Uzbekistan using DNA markers. The material for the research was the species of the family Lamiaceae growing on the territory of Uzbekistan. Species identification was performed using two-four-locus combinations of DNA markers (ITS, rbcL, trnL-trnF, matK, psbA-trnH). 76 consensus nucleotide sequences of the ITS region are used for molecular phylogenetic analysis of the family. The phylogenetic relationships of 26 genera grouped into four subfamilies: Nepetoideae, Lamioideae, Scutellarioideae, Ajugoideae are presented based on nucleotide variability.
