Compte tenu des changements climatiques annoncés, les végétaux risquent d'être confrontés, dans un proche avenir, à des épisodes de sécheresse sévères de plus en plus fréquents. Afin de prédire l'impact de telles contraintes sur la productivité et le rendement des plantes cultivées, il convient d'étudier l'effet du manque d'eau sur l'activité photosynthétique, le transport et l'accumulation des sucres. Dans un premier temps, la croissance, le développement, la biomasse et la photosynthèse de huit écotypes d'Arabidopsis thaliana ont été caractérisés. Trois de ces écotypes (Col-0, Mt-0 et Shahdara) ont ensuite été soumis à une période de déficit hydrique. Une chute du contenu relatif en eau des rosettes (RWC), de la conductance stomatique (gs...
