Gene Regulatory Network, in Reproductive Organs, During Sex Determination (GENDER)

Coordinator: Abdelhafid Bendahmane

Post-doc project selected in 2012 – Person recruited: Maria Victoria Gomez Choserot / Céline Camps

In melon, sex determination is governed by the a gene and the g gene, and the interplay of alleles of these two genes results in a range of sexual types. Cloning of the a gene revealed that andromonoecy results from a mutation in the active site of CmACS-7. The cloning of the g gene revealed that the transition from male to female flowers results from an epimutation of CmWIP1. We also showed that CmWIP1 represses CmACS-7 expression to allow stamen development. The goal of this project is to use the cloning of CmACS-7 and CmWIP1 as a starting point to understand how these two genes determine the sex of the plant. The proposed strategy relied on integrative analyses of datasets that we obtained from the combination of different omics tools and the validation of the concepts, using the TILLING approach.
