A 2 years post-doctoral position supported by Bordeaux Plant Sciences research program is available in UMR Ecophysiology and Grape Functional Genomics (EGFV) and UMR Biology of Fruit and Pathology (BFP) in Bordeaux, France. This post-doc position is one of 19 offered positions as part of Bordeaux University excellence BPS program, which will provide access to many scientific events and resources.
Job description: The objective of this post-doc is to characterize the relationships between vascular and bud phenology in grapevine, with a focus on the mechanisms involved. The main objective is to determine whether grafting scions with rootstocks with contrasting dormancy behaviors could be leveraged to adapt grapevine to climate change. This integrative project aims to combine complementary approaches to understand the timing of vascular and bud development, from genomics to imaging techniques. The aims of the project are:
- Explore the best markers to characterize rootstock/scion/bud transport
- Characterize rootstock/scion/bud transport occurring during bud burst in grafted grapevines
- Identify the rootstock/scion/bud signals that could regulate the progression of dormancy and bud burst in grafted grapevines.
The progression of dormancy will be evaluated by well-established forcing protocols in different genotypes of grapevine. Genotypes with the most contrasting dormancy behaviors will be identified and grafted together. Graft union formation and the longer-term consequences of grafting together genotypes with different dormancy behaviors will be characterized. The postdoc will establish methods to characterize the trafficking between the scion and rootstock, and wood and bud of grapevine during the onset of bud break. The postdoc will also attempt to identify which molecules potentially being trafficked by using mass spectrometry imaging in addition to transcriptomics, metabolite and hormone quantification.
Environment: The postdoc will be based at the EGFV, recognised world-wide for its expertise in viticulture. We are located on the plant science campus of the INRAE (French National Research Institute for Agriculture, Food and Environment).
Bordeaux is an easy-going and enjoyable UNESCO world heritage city with many cultural, social, sportive events, famous for its vineyards and only one hour away from marvellous sand beaches.
We are looking for highly motivated candidates with a good publication track-record and a strong commitment to research. English communication skills are expected.
Skills in microscopy, metabolomics and plant physiology are required
