Description
Cultivated Bidens (Coreopsideae) is a common ornamental flower bedding plant from the Asteraceae. Currently, our lab is utilizing a cultivar of Bidens called “Compact Yellow” as a new model system to study flower development and genetics in the Asteraceae. Ornamental bidens have been historically classified as the species Bidens ferulifolia; however, it is unclear if this name has precedent as many herbarium collections use the name Bidens aurea interchangeably. Recent phylogenetic studies found B. ferulifolia specimen to be more closely related to the species B. andicola than B. aurea. To better determine the true parentage of B. ferulifolia we are utilizing our recently assembled genome of Bidens cv. “Compact Yellow” to compare to whole genome sequence data of B. aurea, B. ferulifolia, and B. andicola herbarium specimens. While collecting tissue we noted that the specimen looked very different under the same species classification. In this same study we are also comparing outwards toward this entire Bidens genus by analyzing whole chloroplast genome data via comparative genomics.
