Do chromosome numbers reflect phylogeny? New counts for Bombacoideae and a review of Malvaceae s.l.

Unlabelled: •

Premise Of The Study: Whole genome duplication (WGD) and specific polyploidy events marked turning points for angiosperm genome structure and evolution. Therefore, cytogenetic studies of polyploidy-prone groups such as the tropical Malvaceae and plant formations such as as the Brazilian Cerrado have gained further importance. We present new chromosome counts for Cerrado Bombacoideae and revised chromosome numbers for the Malvaceae s.
