Reconstructing the ancestral flower

Kristel Schoonderwoerd

The early evolution of flowers remains something of a mystery. As part of her Master’s research, Kristel Schoonderwoerd, PhD Candidate in the Friedman Lab, joined a large international team to reconstruct the ancestral flower based on DNA and floral characteristics of known flowers. The results are published in Nature Communications. more» abstract»

Family reunion of tulip trees

Imagine not seeing your closest living relative for ten or fifteen million (yes million) years. And on top of that, you and your closest living relative end up on different continents. So much time, so much opportunity for evolutionary divergence. The two extant species of tulip trees, Liriodendron tulipifera (eastern North America) and Liriodendron chinense (eastern and central […]

Asymmetric gene flow in Phlox

Phlox growing in the Weld Hill Greenhouses

Federico Roda,  Robin Hopkins and colleagues used genomic analyses to examine the role of gene flow in flower color divergence in Phlox drummondii. Comparing transcriptomes between four Phlox species, they found asymmetric gene flow consistent with the asymmetric morphological divergence in flower color. The results are published in Molecular Ecology. abstract »
