Context - History

Since 2004, PHENOPSIS has been used in the GABI-GENOPLANTE project to analyse the variability of leaf growth and transpiration in a natural collection of 24 Arabidopsis thaliana accessions and their response to a range of soil water deficits.

Through this work, an accession with very low sensitivity to water stress was identified (Granier et al., 2006). By decomposing leaf growth into underlying variables such as expansion rate and duration, number and size of epidermal cells in the leaves, compensations between these variables were revealed (Aguirrezabal et al., 2006). PHENOPSIS was also used to analyse the effect of water stress on the cell cycle and endoreduplication process in leaves of transgenic lines under- or over-expressing genes controlling these processes in the DAGOLIGN Research Training Network project (Cookson et al., 2006).
