“…Lineages A and b1 were characterized by the synapomorphic substitutions in the trnL-trnF and trnStrnG spacers. The genetic divergence revealed between three lineages (Table 4) was high and comparable to the divergence among the Oxytropis species within different sections (Artyukova and Kozyrenko, 2012;Kholina at al., 2016) and between closely related species of other genera, for instance Megadenia (Artyukova et al, 2014) and Iris series Psammiris (Kozyrenko et al, 2009).…”

Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA-trnH, trnL-trnF, and trnS-trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range. The levels of haplotype and nucleotide diversity varied in the range of 0.133-0.911 and 0.0002-0.0059, respectively. The highest values of these parameters are characteristic of populations located in the Barguzin depression. Variable sites detected within the intergenic spacers allowed the identification of eleven haplotypes; nine of them were found in the populations from the Barguzin depression and only two haplotypes were found in the populations from the Yeravna depression. No common haplotypes for all four populations were found. A high level of population differentiation (Φ ST = 0.758, P < 0.0001) and the absence of evidence for isolation by distance were also found in O. glandulosa. Genealogical and phylogenetic analyses and Bayesian analysis of the genetic structure showed a clear division of the studied populations of O. glandulosa into three major lineages.

PremiseAstragalus (Fabaceae), with more than 3000 species, represents a globally successful radiation of morphologically highly similar species predominant across the northern hemisphere. It has attracted attention from systematists and biogeographers, who have asked what factors might be behind the extraordinary diversity of this important arid‐adapted clade and what sets it apart from close relatives with far less species richness.MethodsHere, for the first time using extensive phylogenetic sampling, we asked whether (1) Astragalus is uniquely characterized by bursts of radiation or whether diversification instead is uniform and no different from closely related taxa. Then we tested whether the species diversity of Astragalus is attributable specifically to its predilection for (2) cold and arid habitats, (3) particular soils, or to (4) chromosome evolution. Finally, we tested (5) whether Astragalus originated in central Asia as proposed and (6) whether niche evolutionary shifts were subsequently associated with the colonization of other continents.ResultsOur results point to the importance of heterogeneity in the diversification of Astragalus, with upshifts associated with the earliest divergences but not strongly tied to any abiotic factor or biogeographic regionalization tested here. The only potential correlate with diversification we identified was chromosome number. Biogeographic shifts have a strong association with the abiotic environment and highlight the importance of central Asia as a biogeographic gateway.ConclusionsOur investigation shows the importance of phylogenetic and evolutionary studies of logistically challenging “mega‐radiations.” Our findings reject any simple key innovation behind high diversity and underline the often nuanced, multifactorial processes leading to species‐rich clades.

Tension zone trapped by exogenous cline: Analysis of a narrow hybrid zone between two parapatricOxytropisspecies (Fabaceae)

Hybrid zones have been widely highlighted for their interest in understanding evolutionary processes. It is generally accepted that hybrid zones can be maintained in a balance between dispersal and selection. However, the selective forces can either be endogenous (i.e., genetic incompatibilities between parental taxa) or exogenous (i.e., parental taxa are adapted to different environments). In this study, we evaluated these alternatives and determined the maintenance of a narrow hybrid zone between parapatric distributed Oxytropis diversifolia and O. leptophylla in Nei Mongol, China. For 507 individuals sampled from two populations in the hybrid zone, 12 O. diversifolia populations and five O. leptophylla populations, we measured leaf‐morphological characteristics, quantified genetic structure using 11 nuclear microsatellite loci and five chloroplast DNA intergenic regions, collected micro‐ and macrohabitat data, and conducted geographical cline analysis. We found that the two species differed in leaf morphology, and putative hybrids showed either intermediacy or a bias to O. diversifolia. Parental taxa formed two genetically distinct clusters, while populations in the hybrid zone consisted of both parental forms and various admixed individuals, exhibiting a bimodal pattern. The hybrid zone was coupled to ecological transitions of both microhabitat (i.e., the slope) and macroclimatic conditions. However, the genetic clines were significantly narrower than the environmental cline. Our results indicate that endogenous selection can be primarily responsible for maintaining the hybrid zone, while local adaptation accounts for the position of the zone. We further suggest the probable outcome of hybridization could be introgression.
