Název v původním jazyce

Whole-genome triplication and species radiation in the southern African tribe Heliophileae (Brassicaceae)

Popis výsledku v původním jazyce

The unigeneric tribe Heliophileae includes ca. 90 Heliophila species, all endemic to southern Africa. The tribe is morphologically the most diverse Brassicaceae lineage in every aspect of habit, foliage, flower and fruit morphology. Despite this diversity, virtually nothing is known about its origin and genome evolution. Here we present the first in-depth information on chromosome numbers, rDNA in situ localization, genome structure, and phylogenetic relationship within Heliophileae. Chromosome numbersdetermined in 27 Heliophila species range from 2n = 16 to 2n = ca. 88, but 2n = 20 and 22 prevail in 77% of the examined species. Chromosome-number variation largely follows three major lineages (A, B, and C) resolved in the ITS phylogeny. Clade A species mostly have a chromosome number of 2n = 20, whereas 2n = 22 is the dominant number in clade C (2n = 16 and 22 were counted in two diploid species of clade B).
