Abstract

Angiosperm evolution involves a major transition from spiral to whorled arrangements of floral organs. Examination of the genetic programs specifying floral organ identity in Nigella damascene, a species of Ranunculaceae with spiral flowers, illuminates the molecular basis of how spiral flowers can have flexible numbers of floral organs.

(a) Geographical distribution of the sampled populations and six clades; (b) the median-joining network of the 18 chloroplast haplotypes of Cyclocarya paliurus. Circle sizes are proportional to the haplotype frequencies. Black dots indicate hypothetical haplotypes. Solid bars indicate the number of mutational steps. See Kou et al. 2016 for details.

Lauren Gonzalez awarded SSB Grant!

October 29th, 2015
By Gitzendanner, Matt

TropaeolumCongratulations to Lauren Gonzalez who was recently awarded a Graduate Student Research Award from the Society of Systematic Biologists for her proposal titled “Elucidating the Evolutionary History of Tropaeolum (Tropaeolaceae): Implications for Historical Biogeography, Trait Evolution, and Conservation”

 

Tropaeolum (Tropaeolaceae) comprises ~ 90 species native to Central and South America that are distributed throughout the Andes, within a variety of different habitat types, including several biodiversity hotspots. They also show great variation in floral morphology (e.g. color, shape, size) and some species have been important cultivars around the world.  Because of its distribution and diversity, this genus represents an ideal system to study how geological and environmental processes have affected plant evolution in South America. The goals of this study are to resolve the phylogeny of Tropaeolum using a next-generation sequencing approach and subsequently explore biogeography, trait evolution, and conservation status.
