BioGAP

Biotechnology and Management of Pathogens in Agriculture, A Unit of Charles Viollette Research Institute

BioGAP is ISA Lille’s biotechnology research unit, specializing in pathogen management in agriculture, most notably septoria diseases, important foliar diseases of winter wheat worldwide.

ISA Lille’s BioGAP laboratory has studied septoria diseases for many years and was the first laboratory to reproduce the full cycle of Phaeosphaeria nodorum under in vitro conditions. Today, Mycosphaerella graminicola is the most frequently occurring and the most damaging pathogen on wheat crops. We study the importance of sexual reproduction, the variations of pathogenicity and the plant/pathogens interactions for the wheat/M.graminicola pathosystem.

Another research thematic of the laboratory includes the study of new crop protection methods (elicitors, biocide natural compounds). Cryptosporidium is a genus of protozoan parasite causing gastroenteritis in humans and livestock. As cattle are considered as primary parasite reservoirs, the first goal of our research is to study the parasite population structure in calves by a biomolecular approach. The second purpose is to develop a Lab-on-a Chip system enabling to detect oocysts viability.
