The goal of the proposed project is to enhance grapevine drought and heat tolerance through genetic improvement and better management practices to enable greater adaptation to changing climatic conditions. The project would complement ongoing Vitis gene discovery and functional genomics projects that aim to improve disease resistance in grapevine cultivars

Descriptif
Improve drought and heat tolerance of grapevine cultivars (Vitis vinifera L. and hybrids), thus overcoming major limiting factors in grapevine production.
The objectives are : 1) analyze differential gene expression patterns of drought- and heat-stressed grapevines to identify genes involved in drought and heat tolerance ; 2) incorporate drought and heat tolerance in target cultivars using a technique in molecular biology termed “cisgenic engineering” ; and 3) tudy the drought and heat tolerance of V. vinifera scions grafted on various Vitis rootstocks. The project utilizes newly available grape genetic engineering techniques to incorporate drought and heat tolerance into elite germplasm. Cisgenic engineering, which involves using genetic elements from the Vitis genome to incorporate desirable traits, promises to be consumer- and eco-friendly, ensuring no possible release of transgenes into the environment. Further, knowledge obtained from scion-stock interaction of Vitis cultivars and rootstocks will enable the adoption of improved technology by growers for successful grapevine cultivation.
