Genetic structure of the Anthyllis vulneraria L. s. l. species complex in Estonia based on AFLPs

Abstract

Anthyllis vulneraria L. (Fabaceae) s. lato includes many cryptic taxa, ranging from 25 to 60 subspecies according to different authors. The delimitation of intraspecific taxa of A. vulneraria s. lato has always been complicated and inconsistent. Different data sets (multivariate analyses of morphological variation, allozymes, chloroplast SSRs and ITS) have not resolved the existing problem with distinguishing some subspecies. We used the amplified fragment length polymorphism (AFLP) analysis to describe the differentiation in this species complex and to characterize variation on a geographic scale. Some correlation was found between genetic variability and geographic distribution (western-eastern directional variation), but AFLP data analysis did not reveal clear intraspecific structure of the seven analysed taxa. The analysed specimens did not comprise groups correlated with the subspecies. © 2008 Versita Warsaw and Springer-Verlag Berlin Heidelberg.
