Abstract

The Coreopsideae is an ecophysiologically diverse tribe of plants in the sunflower family (Asteraceae) whose species inhabit a broad range of habitats, from tropical islands and aquatic ecosystems to grasslands and deserts. To resolve the evolutionary history of the tribe, two regions of the chloroplast genome and one from the nuclear genome were sequenced for approximately 75 species in Coreopsideae. The resulting phylogeny will be used to infer the evolution of ecological characteristics, such as a higher tolerance for arid climates or for gypsum substrates.
