Abstract Detail

Phylogenomics and evolution of Superrosids

Phylogenomics and evolution of Superrosids.

Rosids represent a highly diverse lineage of eudicots, with over 70,000 species in 17 orders and ~140 families. Rosids include many economically important species, such as legumes (Fabaceae: e.g., soybean, peanut, common beans), gourds (Cucurbitaceae: cucumber, squash, watermelon), Rosaceae (peach, apple, strawberry, rose, and related fruits and flowers), Brassicaceae (cabbage, cauliflower and related vegetables, and the model plant Arabidopsis thaliana), Malvaceae (cotton, cacao). Rosids also include most of the deciduous trees that make up hardwood forests, such as oak, beech, birch, poplar, cherry, hickory, elm and honey locust. Four orders of rosids, Fabales, Cucurbitales, Fagales, and Rosales form a highly supported clade and contain numerous nitrogen-fixing species. In addition, many groups exhibit other important characteristics, such as the specialized defense compounds glucosinolates in Brassicales. Closely related to rosids are the orders Vitales (grape) and Saxifragales (currant, peony), which, together with rosids, are referred as superrosids. In recent years, much progress has been achieved in the understanding of phylogeny and evolution of rosids/superrosids and the orders/families therein, benefiting from rapid advances in sequencing technologies and phylogenetic methods. This colloquium aims to report the recent progress in this area.
