Tracing the evolutionary history of the little-known Mediterranean-Macaronesian genus Andryala (Asteraceae) by multigene sequencing

Popis výsledku v původním jazyce

Andryala (Asteraceae: Cichorieae) is a little-known Mediterranean-Macaronesian genus whose taxonomy is much in need of revision. In order to elucidate species relationships in the genus, we performed phylogenetic analyses of nucleotide sequences of the internal transcribed spacers (ITS) and the external transcribed spacer (ETS) of nuclear ribosomal DNA (nrDNA), two chloroplast (cpDNA) markers (trnT-trnL and trnV-ndhC intergenic spacers), and one single-copy nuclear gene (sqs) using Bayesian and maximumparsimony methods of inference. While cpDNA analysis confirmed a previously inferred chloroplast capture event with the sister genus Pilosella, all nuclear markers supported the monophyletic origin of Andryala. However, determining accurate phylogeneticrelationships within the genus was quite challenging due to very low levels of nucleotide divergence of all nrDNA and cpDNA markers and a high degree of homoplasy and incomplete lineage sorting in the variable sqs marker. Although none of
