Mobility project

This project focused on the genetic control of the response to soil water stress in fruit trees implying the functional genomics applied to adaptation to soil water stress in apple tree. I will study the expression of genes involved in the response of apple seedlings grown under controlled conditions and subjected to soil water stress. Two complementary approaches will be performed. In the first one, transcriptomic analyses will be performed on previously acquired data. In the second approach, gene expression studies will be carried out on as set of candidate genes resulting from the confrontation between QTL zones and transcriptomic data.

Our final goal is to highlight candidate mechanisms involved in the differential response of different apple tree cultivars to soil water restriction.

Biography & research interests

The team AFEF (Architecture et Fonctionnement des Espèces Fruitières) from the l’UMR AGAP (Amélioration Génétique et Adaptation des Plantes méditerranéennes et tropicales) is very serious and works on research topics highly relevant. Indeed, I am very interested in fruit species because they are not as well studied as annual and herbaceous species on the one hand and because they have the potential to climate, environment and soil adaptation on the other hand. Furthermore, and as I worked on the morphological, agronomic and genetic aspects of fruit species, I believe that the line of research that deals with tolerance to water stress of apple in the genetic control of soil-tolerance to stress is a topic that interested me particularly, especially when the transfer of such knowledge can be beneficial to Tunisia, in addition to the eventuality to initiate such research thematic in the future within the laboratory of Molecular genetics, immunology and Biotechnology to which I belong.
