Objectifs
Our long-term objective is to enhance the tolerance of different plants and crops to a combination of drought stress and heat shock. Our specific objectives are : 1. Study the regulation of sucrose and proline biosynthesis during a combination of drought stress and heat shock in Arabidopsis. 2. Develop a screen to test the resistance of Arabidopsis plants to a combination of drought stress and heat shock and use the screen to test mutants altered in sucrose and proline biosynthesis. 3. Attempt to enhance the tolerance of Arabidopsis plants to a combination of drought stress and heat shock by expressing specific regulatory genes in transgenic plants

Descriptif
We will perform biochemical, physiological and molecular measurements, as well as use different mutants and transgenic lines to test our hypothesis. In addition, we will attempt to enhance the tolerance of transgenic Arabidopsis plants to a combination of drought stress and heat shock using different regulatory genes previously identified by our gene-expression studies as specifically expressed in cells during the stress combination.
