Molecular phylogeny of genus Guizotia (Asteraceae) using DNA sequences derived from ITSBekele E, Geleta M, Dagne K, Jones AL, Barnes I, Bradman N, Thomas MG
AbstractComplete sequences for the internal transcribed spacers of the 18s-26s nuclear ribosomal DNA were generated to establish phylogenetic relationships among five species of the genus Guizotia. Parsimony analysis and pairwise distance data produced a single tree with four clearly distinguished clades that accord with previously reported chromosomal data. The clades produced here have been discussed with reference to existing taxonomic treatments. It appears that Guizotia scabra ssp. scabra, G. scabra ssp. schimperi and Guizotia villosa have contributed to the origin of Guizotia abyssinica, the cultivated species of the genus. The present composition of the species of genus Guizotia and the subtribe the genus presently placed in are suggested to be redefined
