Organ symmetry establishment during gynoecium development

open access: yesCurrent Opinion in Plant Biology
Symmetry is a key factor in the morphological diversity and reproductive success of angiosperms (flowering plants). The gynoecium, the female reproductive organ of the flower, displays remarkable variation in symmetry types, ranging from bilateral to radial, from its base (ovary) to its apex (style). Proper tissue growth and differentiation occur along

A conserved role for the NAM/miR164 developmental module reveals a common mechanism underlying carpel margin fusion in monocarpous and syncarpous eurosids.

open access: yesFrontiers in Plant Science, 2016
The majority of angiosperms are syncarpous- their gynoecium is composed of two or more fused carpels. In Arabidopsis thaliana, this fusion is regulated through the balance of expression between CUP SHAPED COTYLEDON (CUC) genes, which are orthologues of ...
