The plant genus Bidens (Asteraceae or Compositae; Coreopsidae) is a species-rich and circumglobally distributed taxon. The 19 hexaploid species endemic to the Hawaiian Islands are considered an iconic example of adaptive radiation, of which many are imperiled and of high conservation concern. Until now, no genomic resources were available for this genus, which may serve as a model system for understanding the evolutionary genomics of explosive plant diversification.

Hawaiian plant radiations often result in lineages with exceptionally high species richness and extreme morphological and ecological differentiation. However, they typically display low levels of genetic variation, hindering the use of classic DNA markers to resolve their evolutionary histories. Here we utilize a phylogenomic approach to generate the first generally well-resolved phylogenetic hypothesis for the evolution of the Hawaiian Bidens (Asteraceae) adaptive radiation, including refined initial colonization and divergence time estimates.

Throughout the world DNA banks are used as storage repositories for genetic diversity of organisms ranging from plants to insects to mammals. Designed to preserve the genetic information for organisms of interest, these banks also indirectly preserve organisms' associated microbiomes, including fungi associated with plant tissues. Studies of fungal biodiversity lag far behind those of macroorganisms, such as plants, and estimates of global fungal richness are still widely debated.
