Understanding the genetic and molecular bases underlying natural variation in seed longevity
A key factor that contributes to seed vigor during germination is the capacity of seeds to remain alive for extended periods of time in the dry state (i.e. longevity). Seeds with elevated longevity will deteriorate only slowly during conservation, and will retain high germination vigor. Both the seed industry and gene bank curators express the need for tools to better understand, improve and predict longevity. The objective of this project is to elucidate the principal actors involved in seed longevity in Medicago truncatula using an innovative approach integrating natural genetic variation, functional genomics and predictive models of longevity. The candidate will rely on already existing longevity data obtained for 340 Medicago accessions, data from genome-wide association studies (GWAS), QTL data and data from gene co-expression networks of seed maturation (Verdier et al., Plant Physiol., 2013; Righetti et al., Plant Cell, 2015). Research will be performed in the group of Dr. Julia Buitink at the Institut de Recherche en Horticulture et Semences and in collaboration with other Inra laboratories working on GWAS.
The ideal candidate should have a Ph.D. in plant sciences with a demonstrated record of scientific productivity. We seek an individual with experience in molecular biology and/or molecular genetics. Experience with gene network analysis tools will be appreciated. Knowledge of plant or seed biology is an asset.
