Services offered

M3P gathers multidisciplinary experts including plant scientists, software / hardware engineers and technicians. All hosted experiments will be jointly operated by dedicated technicians and engineers and the hosted team. The recording, storing, handling, and first analysis of raw data (images, meso- and micro- climate, output from growth sensors) will be automatically or semi-automatically performed thanks to dedicated workflows connected with our databases. Data will be accessible via web services with customized right accesses.

Specific services involving the three installations are :

  •  PhenoArch is the largest and also the most recent platform within M3P. It embarks 1680 plants for multi trait association studies under contrasting soil water status and climatic scenarios. Traits measured are biomass (through biovolumes), transpiration and architecture. We also develop algorithms to infer radiation use efficiency and water use efficiency. The platform is best suited for diversity panel and quantitative genetics studies. In the last 4 years, it has been successfully used with maize, wheat, grapevine, apple tree and cotton.
  •   Phenodyn is based on the dynamic recording of organ growth using displacement transducers while pots are individually placed on balances allowing automatic recording and manipulation (through peristaltic pumps) of soil water in the greenhouse. The same set-up is installed with a limited number of balances in three growth hambers allowing the imposition of step changes or extremes climatic conditions. It allows characterization of growth and transpiration of 500 plants in fluctuating environmental conditions. Typical tested populations were multi-parental population, introgression libraries and collection of mutants and specific GM.
  • Phenopsis is an automatic watering and imaging robot installed in three growth chambers, each holding 500 plants.Initially developed for the model plant Arabidopsis thaliana, it has been recently upgraded to host other species with different aerial architecture such as canola, tomato or Brachypodium. It can take RGB (top and/or side view), infra-red and fluorescence images. It has served for multi-trait QTL analyses involving leaf expansion, cell division and leaf formation with contrasting soil water status. It has also been used to test large series of accessions from contrasted origin and targeted transgenic plants and associate phenotypes with transcriptomics, proteomics and metabolomics.
