Zygomorphy evolved from disymmetry in Fumarioideae
Floral bilateral symmetry (zygomorphy) has evolved at least 70 times during the history of angiosperms, whilst radial symmetry (actinomorphy) is the ancestral and most common state for angiosperms as a whole. Sauquet et...

Pollination, flower size variation and floral symmetry
The pollinator-mediated stabilizing selection hypothesis suggests that the specialized pollination system of zygomorphic flowers might cause stabilizing selection, reducing their flower size variation compared to...
Virus-induced gene silencing and evo-devo studies in Cysticapnos
Gene silencing studies are increasingly being used to unravel the role of developmental genes. Hidalgo et al. report the establishment of virus-induced gene silencing (VIGS) in Cysticapnos vesicaria, a member of the...
