Biologists have found a rare gene that is responsible for the immune system of plants

mechanisms of the immune system of a small bloominga plant known as Arabidopsis thaliana. PRoTECT is an International Research Teaching Group (IRTG) founded in 2016 with the University of Göttingen and the University of British Columbia in Vancouver. The aim of the study is to identify and describe a specific gene of a plant that is particularly resistant to diseases. Scientists have noticed that plants that do not possess the previously little-known glycosyltransferase UGT76B1 gene accumulate active acids. In addition, they show significantly increased resistance to pathogens. However, this resistance is accompanied by extremely slow growth.

“We managed to decipher the molecular connectionbetween gene product and acid inactivation during normal plant growth, ”explains Prof. Ivo Feussner of the Göttingen Center for Molecular Biological Sciences (GZMB). Understanding this interaction provides scientists with a promising approach to increasing the natural resilience of crops. Research results, for example, can be used to help breeders isolate less susceptible plants. This will improve food security and reduce the use of pesticides.
