Identifying sex-determining genes in the dioecious plant Silene latifolia – PlantGenomYX

Submission summary

About 15000 flowering plants are dioecious (= sex is carried by different individuals). These plants are over-represented among crops (~17%). Understanding sex determination in dioecious plants is thus important for both fundamental and applied research. However, despite recent advances on this question, very little data is available. The objective of this proposal is to identify the sex-determining genes in Silene latifolia, one the best studied dioecious plants. We will produce a high-quality XY male genome (thanks to long-read data), combine different approaches (mutant collection, transcriptomic data) to identify candidate genes, and validate and characterize those candidates (thanks to Crispr-cas9). Here are joined two partners (LBBE Lyon et IPS2 Saclay) with a strong expertise in genomics, bioinformatics, functional and evolutionary studies, which is needed for this proposal.
