The team of our Laboratory of “Biotechnologies and Genetic Valorization of Plants” includes teacher-researchers specialized in microbial biotechnology, plant genetics and ecology whose work focuses on: microbial biotechnology and analysis of plant genomes for the development of local biodiversity and sustainable exploitation of cultivated and spontaneous plants. This work aims to contribute to the resolution of agronomic and environmental problems using biotechnological tools. The research themes developed by our laboratory are :
– Biofertilizers based on Actinomycetes : The excessive use of chemical fertilizers/pesticides has become a problem. The search for inexpensive, ecologically viable and efficient alternatives has become a requirement. Our objective is to develop a new Actinomycete-based fertilizer product capable of both solubilizing phosphate and potassium rocks by ensuring the mobilization of these nutrients towards the plant rhizosphere (Sugar beet, Cereals, others…). In addition, we aim at developing bio-fertilizers that also express additional activities: protection against phytopathogens (“Biopesticide” and “bio-immune” plant defense). This line of research is an important way to design crop itineraries that respect the rules of low-input agriculture.
– Fodder genetic resources: Thanks to their fodder quality, their capacity to fix the soil and improve its fertility through root nodules, fodder species are a plant material of choice and of great agronomic interest. Among these species, our interest focused on species of both genera: Medicago and Hedysarum. The traced objectives are the evaluation, conservation and improvement of these species.
– Fruit genetic resources: Fruit species play an important socio-economic role and contribute to the stability of ecosystems. Our interest has focused on carob, pomegranate, vine, walnut, plum and apple. The objectives of our research work are the evaluation of genetic diversity and its structuring, the valorization of germplasm and the agronomic and agro-industrial valorization of local cultivars characterized by considerable adaptive potentialities.
