Opis (eng)

Abstract: With many subordinate or presumably closely related local endemic or subendemic taxa, Stachys recta forms a polymorphic group. To explore the variation in relative genome size and to identify patterns that may unravel the evolutionary history of the taxonomically complex S. recta group, relative genome size (RGS) was assessed for a total of 155 accessions from 55 populations of 18 taxa in southeastern Europe (S. albanica, S. angustifolia, S. anisochila, S. atherocalyx, S. beckeana, S. goulimyi, S. graeca, S. leucoglossa, S. parolinii, S. patula, S. recta subsp. baldaccii, S. r. subsp. doerfleri, S. r. subsp. olympica, S. r. subsp. recta, S. r. subsp. rhodopaea, S. r. subsp. subcrenata, S. tetragona and S. zepcensis). Flow cytometry was used to estimate the relative genome size, expressed here as a ratio of fluorescences between the individual and the standard (Bellis perennis), and varying from 0.43 to 0.71. Although several studies of other taxonomically complex taxa have shown correlations between intraspecific GS variation and morphology or environmental factors, and geographic segregation, we found no patterns in the RGS variation of the analysed samples with respect to taxonomy, geography or ecology.
