Biology of phytopathogenic bacteria, fungi, nematodes and viruses
[BRPP2101]
[37.5h + 15h] 5 credits
This course is taught in the 2d semester.
Teacher(s): Claude Bragard(coord.), Jean Colin, Anne Legrève
Language: French
Level: Second
Aims
This course must be considered in a broader context with the target to offer an complete knowledge about the main phytopathogenic organisms responsible of plants diseases : viruses, bacteria, fungi and nematodes.
It aims to develop advanced skills in the analysis of these agents, in the understanding of their functions, and in their interaction capacities with plants.
The anatomical and morphological characteristics of the phytopathogenic nematodes will be studied, and illustrated with different models. Control methods and related technologies will be more particularly explored (identification and population density evaluation methods, damages, epidemiology data, host-parasite relationships, nematodes reproduction and survival, control strategy ).
