Affy_popsec_nancy_pophydro_roots_poplar -Molecular bases of acclimation and adaptation to water deficit in poplar

ABSTRACT: affy_popsec_nancy_pophydro_roots_poplar - This project aims to identify genes of interest for control of root growth in response to water deficit in a tree species: poplar. We look for genes and gene expression networks related to drought stress. We intend to analyse the transcriptome in root apices of cuttings grown in hydroponics and osmotically stressed with PEG. Root apex is the location of root elongation and these analyses intend to identify genes involved in the control of cell expansion and thus of root elongation. Indeed, root growth maintenance in response to water shortage contributes to plant tolerance to water deficit.-Poplar cuttings (cv Soligo) were grown in hydroponics. A moderate water deficit was applied by adding PEG to the nutrient solution (200g/l). After 3 days, the
