Sex phenotypes of the WT and cuc2b mutant. (A) Schematic representation of the distribution of males and females in the monoecious squash plant. Blue=male flower; green=female flower. The red arrow indicates the female flowering transition (FFT), the node at which the first female flower is developed. (B) Distribution of male and female flowers in the first 60 nodes of the wt/wt, wt/cuc2b, and cuc2b/cuc2b mutant plants (total plants=636). In each node, blue and green bars represent the percentage of male and female flowers of the total plants analyzed, respectively.
