Dr. Silvere Vialet-Chabrand

TIGR2ESS:
 
Transforming India's Green Revolution by Research and Empowerment for Sustainable Food Supplies

Silvere is interested in high throughput phenotyping of traits related to photosynthesis and stomatal conductance under a dynamic environment. He has developed tools to identify cultivars with improved photosynthetic performance, which is key to improve yield and global food security in the future. Outcomes from these works have attracted the interest of agritech companies and will improve our understandings of leaf gas exchange and energy balance under fluctuating light conditions. Research is funded by the TIGR2ESS project to support cutting-edge research and innovation addressing key challenges in global food security.

Previous projects:
Wider and faster: high-throughout phenotypic exploration of novel genetic variation for breeding high biomass and yield in wheat
  • Develop novel high throughput screening techniques of stomatal conductance.
  • Identify progeny with less limited photosynthetic capacity and enhanced efficiency, which increase wheat biomass production and yield.

Stomatal-based systems analysis of water use efficiency:
  • Scaling up the OnGuard model (http://www.psrg.org.uk/guard-cell.html) simulating the stomatal behaviour to the canopy level.
  • Improving a dual imaging technic using thermal and chlorophyll fluorescence to assess Water Use Efficiency​

Research interests:
  • Cellular and leaf level dynamic of the stomata.
  • Leaf energy balance and thermography under a dynamic environment.
  • Impact of stomatal conductance limitation on growth and yield. stomatal behaviour from leaf to canopy.
