Evolutionary history of an Irano-Turanian cushion-forming legume (Onobrychis cornuta).

ABSTRACT: The Irano-Turanian region is one of the largest floristic regions in the world and harbors a high percentage of endemics, including cushion-like and dwarf-shrubby taxa. Onobrychis cornuta is an important cushion-forming element of the subalpine/alpine flora of the Irano-Turanian floristic region. To specify the genetic diversity among the populations of this species (including individuals of O. elymaitica), we employed nrDNA ITS and two noncoding regions of plastid DNA (rpl32-trnL_(UAG) and trnT_(UGU)-trnL_(UAA)). The most striking feature of O. cornuta assemblages was the unexpectedly high nucleotide diversity in both the nDNA and cpDNA dataset. In the analyses of nuclear and plastid regions, 25 ribotypes and 42 haplotypes were found among 77 and 59 accession
