We study the ability of plants to defend themselves against pathogens. In many cases, this disease resistance is conferred by specific disease resistance (R) genes, many of which have been cloned from solanaceous crop plants (potato, tomato, pepper). However, the molecular analysis of these genes is much easier in model plants such as tobacco. The generation of such model systems necessitates the ability to generate transgenic plants, which requires specialized sterile environments, including plant tissue culture chambers. The latter allow for precise control of temperature, light and humidity and are used for the regeneration of transgenic material. This material is in turn used either to establish experimental systems or to validate candidate genes and proteins for their involvement in plant defences. The information gleaned from these experimental systems can then be applied to the better use of R genes in their native context in crop plants.
