Among the genes characterized and discovered in his laboratory are the genes of radish reserve proteins since 1985, the genes of LEA (Late Embryogenesis Abundant) proteins and their regulation, proteins omnipresent in seeds, whose function is undoubtedly to facilitate the survival of the seed during its dehydration, the first gene of a lipid transfer protein in 1988 with Jean-Claude Kader and Père Puigdomenech, then other members of this family involved in the defense against pathogenic fungi, several genes essential for the proper development of embryogenesis, the ABI 5 regulatory gene involved in regulating maturation and seed germination in 2001, several genes involved in controlling ribosomal RNA formation (fibrillarine, nucleolin, snoRNA) and ribosomes that synthesize proteins, several genes involved in lipid biosynthesis in rapeseed, and, recently, one of the genes responsible for the aroma of Basmati rice, as well as the first gene regulating cell death in plants...
