Reconstruction of phylogenetic relationships in a highly reticulate group with deep coalescence and recent speciation (Hieracium, Asteraceae)

Original language description

Phylogeny reconstruction based on multiple unlinked markers is often hampered by incongruent gene trees, especially in closely related species complexes with high degrees of hybridization and polyploidy. To investigate the particular strengths and limitations of chloroplast DNA (cpDNA), low-copy nuclear and multicopy nuclear markers for elucidating the evolutionary history of such groups, we focus on Hieracium s.str., a predominantly apomictic genus combining the above-mentioned features. Sequences of the trnV-ndhC and trnT-trnL intergenic spacers were combined for phylogenetic analyses of cpDNA. Part of the highly variable gene for squalene synthase (sqs) was applied as a low-copy nuclear marker. Both gene trees were compared with previous results based on the multicopy external transcribed spacer (ETS) of the nuclear ribosomal DNA. The power of the different markers to detect hybridization varied, but they largely agreed on particular hybrid and allopolyploid origins. The same crown
