Root Transcriptome of Tunisian Vitis vinifera subsp. sylvestris treated by Salt stress. Vitis vinifera subsp. sylvestris isolate:Tebaba

Salinity is a major constraint for agricultural production in general and for viticulture in particular. Most of the elite cultivated grapevine varieties (Vitis vinifera L.) are grafted on conventional rootstocks but they are becoming more and more affected by climate changes, particularly the increase of salinity. Tunisia has important wild grapevine (V.vinifera ssp. sylvestris) populations among which certain genotypes displayed enhanced tolerance to salinity when compared with conventional rootstocks. Thus, the present project will focus on the search for key regulators involved in salt tolerance from Tunisian wild grapevine accession (Tebaba) using RNAseq technology. This is not only crucial to understand their resistance mechanisms to salt stress, but also the identified molecular markers could be used for an innovative molecular breeding strategy. Consequently, expected findings will be useful to develop new generation of grapevine rootstocks more resilient to global climate change and therefore to promote sustainable viticulture.
