The species of the genus Centaurium Hill are characterized by a pronounced phenotypic
plasticity, while interspecific hybridization readily occurs. Previous studies reported hybridization events between C. erythraea and C. tenuiflorum in the Mediterranean region,
but the status of a potentially hybrid taxon (termed "Centaurium ×tenuiflorum") remains
unclear. Therefore, molecular markers (EST-SSR, ITS, and chloroplast DNA markers) were
combined and their usefulness in estimating overall genetic variability and in identifying
phylogenetic relations between Centaurium taxa was scrutinized. Both EST-SSR and ITS
markers proved to be well suited to distinguish the parental taxa C. erythraea and C.
tenuiflorum, and a putative hybridogenic taxon "C. ×tenuiflorum", the last one being more
related to C. erythraea. Conversely, maternally inherited chloroplast markers (trnL-F, rbcL
and psbA-trnH) nominated C. tenuiflorum as a donor of plastid.
