dc.description.abstract | Although Crepis was the first model plant group in which chromosomal changes were
considered to play an important role in speciation, their chromosome structure and evolution have
been barely investigated using molecular cytogenetic methods. The aim of the study was to provide a
better understanding of the patterns and directions of Crepis chromosome evolution, using comparative
analyses of rDNA loci number and localisation. The chromosome base number and chromosomal
organisation of 5S and 35S rDNA loci were analysed in the phylogenetic background for 39 species of
Crepis, which represent the evolutionary lineages of Crepis sensu stricto and Lagoseris, including
Lapsana communis. The phylogenetic relationships among all the species were inferred from nrITS
and newly obtained 5S rDNA NTS sequences. Despite high variations in rDNA loci chromosomal
organisation, most species had a chromosome with both rDNA loci within the same (usually short)
chromosomal arm. The comparative analyses revealed several independent rDNA loci number gains
and loci repositioning that accompanied diversification and speciation in Crepis. Some of the changes
in rDNA loci patterns were reconstructed for the same evolutionary lineages as descending dysploidy. | pl_PL |
