• Description: GC base pair content is an important character in the description of new taxa of prokaryotes, but its role in plant systematics and evolution is still poorly understood. Using flow cytometry methods (FCM) with PI and DAPI, we estimated base composition in Apiaceae (16 spp.), Brassicaceae (30 spp.), Cyperaceae (135 spp.), Onagraceae (15 spp.), Poaceae (132 spp.) and Salicaceae (20 spp.), and found a significant positive correlation between GC content and genome size.
