“…Caryophyllaceae are a large herbaceous family with most of the species distributed in northern temperate regions, and the tribe Alsineae also represents a large herbaceous lineage mainly distributed in the same regions. In previous dating analyses, however, taxon sampling of Caryophyllaceae mostly focused on several tribes ( Gizaw et al., 2016 ; Jia et al., 2016 ; Xu et al., 2019 ) or genera ( Frajman et al., 2009 ; Petri et al., 2013 ; Mahmoudi-Shamsabad et al., 2021 ), and the temporal evolutionary history of Caryophyllaceae with a comprehensive tribal level sampling or Alsineae with a comprehensive generic sampling has not been investigated. Exploring the temporal origination and diversification of major clades within these two groups may provide a new case study in understanding the relationship between global climate change and biological evolution, and also would be important to better understand the evolutionary history of herbaceous flora.…”

Alsineae are one of the most taxonomically difficult tribes in Caryophyllaceae and consist of over 500 species distributed in the northern temperate zone. Recent phylogenetic results have improved our understanding on the evolutionary relationships among Alsineae members. Nevertheless, there are still some unresolved taxonomic and phylogenetic problems at the generic level, and the evolutionary history of major clades within the tribe was unexplored to date. In this study, we carried out phylogenetic analyses and divergence time estimation of Alsineae using the nuclear ribosomal internal transcribed spacer (nrITS) and four plastid regions (matK, rbcL, rps16, trnL-F). The present analyses yielded a robustly supported phylogenetic hypothesis of the tribe. Our results showed that the monophyletic Alsineae are strongly supported to be the sister of Arenarieae, and the inter-generic relationships within Alsineae were mostly resolved with strong support. Both molecular phylogenetic and morphological evidence supported the Asian species Stellaria bistylata and the two North American species Pseudostellaria jamesiana and Stellaria americana all should be recognized as new monotypic genera respectively, and three new genera Reniostellaria, Torreyostellaria, and Hesperostellaria were thereby proposed here. Additionally, molecular and morphological evidence also supported the proposal of the new combination Schizotechium delavayi. Nineteen genera were accepted within Alsineae and a key to these genera was provided. Molecular dating analysis suggested that Alsineae splitted from its sister tribe at ca. 50.2 million-years ago (Ma) during the early Eocene and began to diverge at ca. 37.9 Ma during the late Eocene, and divergent events within Alsineae occurred mainly since the late Oligocene. Results from the present study provide insights into the historical assembly of herbaceous flora in northern temperate regions.

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.

Salicornia (Chenopodiaceae) with ca. 25-30 annual, hyperhalophytic succulent species is a taxonomically difficult subcosmopolitan genus. The taxonomic complexity arose from succulent shoots causing a lack of taxonomically useful characters, scarcity and variability of characters, and poor genetic differentiation. The Irano-Turanian region, a major center for several lineages of chenopod diversification, is also an important diversity center and more likely the center of origin of annual Salicornia. This paper presents long-term comprehensive morpho-molecular and cytological studies of the genus in Iran, as the most species-rich country in the Irano-Turanian region. We originally generated 250 sequences of one nuclear (ETS) and two plastid markers (atpB-rbcL spacer, intron rpl16). We analyzed a global ETS dataset including 257 sequences of putative 28 taxa using Bayesian inference and maximum likelihood analysis. In order to evaluate the application of plastid data in species taxonomy in annual Salicornia, we performed numerical morphological analysis (principal component analysis and agglomerative hierarchical clustering) of 186 Iranian accessions using 18 characters. Our results (1) confirm the efficiency of plastid sequences comparing to ETS sequences for clarifying species-level phylogeny of Salicornia; (2) identify the S. persica clade as a monophyletic Irano-Turanian endemic lineage; (3) recognize nine origins of the Irano-Turanian Salicornia based on nuclear ETS sequences; (4) approve the monophyly of tetraploid species using plastid sequences; (5) provide a synopsis and diagnostic key for 10 Iranian taxa of Salicornia; (6) describe S. turanica sp. nov.; (7) classify S. iranica at infraspecific level (S. iranica subsp. iranica, S. iranica subsp. rudshurensis comb. nov., S. iranica subsp. sinus-persica comb. & stat. nov.); (8) suggest three informal taxa to be studied in the future; and (9) discuss the threatened status of Salicorniadominated ecosystems in Iran.
