In this course, to be held for three weeks in the summer of each year, plant biologists will be provided hands-on experience in techniques of molecular analysis of plants, with a strong emphasis, but not exclusively, on working with Arabidopsis as a model. Concepts are transmitted through intensive lectures and discussion periods by invited speakers which deal with their specialty area. The value of the course lies in the training of young scientists who often continue to collaborate for years after they attended this course and in its function in the dissemination of new techniques and conceptual approaches to study plants.
