Isozyme evidence on the specific distinctness and phylogenetic position of Vicia incisa (Fabaceae)

Abstract: Vicia incisa is a taxonomically controversial species that has been also treated as a subspecies of V. sativa because of a great morphological similarity. The phylogenetic position of V. incisa is uncertain because various DNA markers have provided contradictory results. Isozymes of V. incisa encoded by 15 loci and resolved with the use of polyacrylamide gel electrophoresis (PAGE) are described and compared with those of seven related species belonging to sections Vicia, Sepium, Lathyroides and Pseudolathyrus in order to get new evidence about its taxonomic rank and phylogenetic position. Phylogenetic relationships are analyzed with maximum parsimony and neighbour joining methods. Vicia incisa is shown to differ from all three subspecies of V. sativa including, sativa, cordata and nigra, by alternate variants of ten isozymes out of 15 analysed. Instead, V. incisa has much more similarity to V. grandiflora and V. sepium by sharing eight isozyme variants which differ from the subspecies of V. sativa. The most parsimony and neighbour joining analyses of the isozyme variation placed V. incisa as basally linked to the V. grandiflora and V. sepium species couple in the clade of section Sepium (= sect. Atossa), while the subspecies of V. sativa together with V. lathyroides formed a separate clade of section Vicia. The isozyme data provide further support to the species status of V. incisa.
