Phenotyping

Pictures of the plants are taken automatically once a day (once the light is on). In addition, plants are harvested each 2 to 3 days for different destructive measurements to measure a set of leaf growth variables from the cells to whole rosette:

- total rosette area
- number of leaves
- individual leaf area
- epidermal cell number in leaf 6
- epidermal cell area in leaf 6
- extent of endoreduplication in leaf 6
- thickness of leaf 6
- contribution of internal tissues to leaf thickness

PHENOPSIS, an automated platform for reproducible phenotyping of plant responses to soil water deficit in Arabidopsis thaliana permitted the identification of an accession with low sensitivity to soil water deficit.
