Molecular bases of acclimation to water deficit in poplar mature leaves Inra
Cohen, D.; Hummel, I.; Balzergue, S.; Magniette, M.L.; Tisserant, E.; Le Thiec, D.; Dreyer, E.; Renou, J.P.; Bogeat, M.B..
In temperate zones the global change will include a decrease of summer precipitations inducing longer and more severe drought episodes. Transcriptional regulation plays a major role in regulating many biological processes, we looked for gene expression networks related to drought stress. The final aim is to identify candidate genes for water deficit acclimation and/or adaptation in poplar, a model tree species. The transcriptome of two Populus deltoides x nigra genotypes of contrasted tolerance to water deficit (Carpaccio and Soligo) were analysed in young mature leaves, at various stages and intensities of stress. Four watering treatments were applied: control (CTL) watered to field capacity six-times a day; early response to water deficit (EAR): watering...

Monitoring the regulation of gene expression in a growing organ using a fluid mechanics formalism Inra
Merret, R.; Moulia, B.; Hummel, I.; Cohen, D.; Dreyer, E.; Bogeat, M.B..
Background: Technological advances have enabled the accurate quantification of gene expression, even within single cell types. While transcriptome analyses are routinely performed, most experimental designs only provide snapshots of gene expression. Molecular mechanisms underlying cell fate or positional signalling have been revealed through these discontinuous datasets. However, in developing multicellular structures, temporal and spatial cues, known to directly influence transcriptional networks, get entangled as the cells are displaced and expand. Access to an unbiased view of the spatiotemporal regulation of gene expression occurring duringdevelopment requires a specific framework that properly quantifies the rate of change of a property in a moving...

Physiological and transcriptional responses of poplar to water deficit Inra
Kohler, A.; Bogeat, M.B.; Delaruelle, C.; Dreyer, E.; Guehl, J.M.; Martin, F..
The response of Populus trichocarpa x deltoides transcriptome to water-deficit stress wasassessed using experimental conditions that closely approximate stress development in the field.For dehydration treatment, 2-month-old cutting plantlets were grown for 19 days under restrictedirrigation to reach 35% of the transpiration rate of fully watered plants. At this stage, leaf waterpotential and shoot growth were not affected. In contrast, stomatal conductance andphotosynthesis of the fast growing leaf F3 were reduced by 90 and 60%, respectively. Osmoticadjustment was detected in this leaf – full turgor osmotic pressure was 20% higher than in controlplant –. Root growth was stimulated although relative water content was decreased. No osmoticadjustment was...

Physiological and transcriptional responses of Populus euphratica to an increasing drought and a recovery Inra
Bogeat, M.B.; Brosché, M.; Le Thiec, D.; Hukin, D.; Polle, A.; Kangasjarvi, J.; Dreyer, E..
Populus euphratica is a poplar species famous for its ability to cope with high salinity. Moreover, its distribution area comprises deserts with very hot and dry summers. All species of genus Populus are known to be rather drought sensitive and P. euphratica may grow in such dry areas due to its phreatophytic habit. In this experiment, we studied the ecophysiological and transcriptomal responses of P. euphratica to an increasing drought stress. The drought stress was applied for 6 weeks. Growth and physiological parameters were recorded at different stress intensities and root and leaf tissues were harvested for transcriptome analysis. To identify the molecular mechanisms of stress tolerance in P. euphratica we have sequenced ESTs from several normalized...
