Genetic and molecular control of apple tree tolerance to soil water stress.


I defended my PhD in 2007, untitled “Study of the genetic resources of apricot (Prunus armeniaca L.) in Tunisia and their relationship with the Mediterranean variability”, which was conducted in cotutelle between the Laboratory of Molecular Genetics Immunology and Biotechnology of the Faculty of Sciences of Tunis and SIBAGHE doctoral school of SupAgro Montpellier in collaboration with INRA Avignon. I was hired as a university teacher in September 2007at the rank of assistant master in Faculty of sciences of Gafsa, Tunisia. In 2011, I had my transfer to the High Institute of applied biological sciences of Tunis (ISSBAT), university of Tunis-El Manar, Tunisia. My main activities are to set up and ensure courses, practical work and directed work. I ensure courses and practical work on plant biology, reproductive biology in plants, and Improvement and conservation of plant resources. In order to progress in my career, to enhance my research background, and to develop my skills, I chose to get involved in new areas of research and to ask for a postdoctoral stay in INRA-CIRAD Montpellier for which I have applied for the AgreenSkills fellowship. In 2016, I got the opportunity to participate to the recruitment competition of the transition to master conference grade and I succeeded.


Genetic and molecular control of apple tree tolerance to soil water stress.

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.
