Scientists have discovered how a small protein in plants that acts like a molecular form of velcro helps stick to other target proteins, creating new connections that enable plants to respond better to environmental stresses like drought, salt and pathogens.
Researchers from the 糖心原创’s School of Biosciences co-led the study in collaboration with the Universities of Durham , Liverpool and Cambridge. In a world first, the UK team has analysed the entire molecular machinery that adds and takes away the SUMO velcro strip. The results have been published today in .
The team were able to detect where all 32 parts of the SUMO machinery are located by tagging each with a fluorescent tag, then studying which change after exposure to an environmental stress.
This new study shows that different parts of the SUMO machinery are regulated by distinct environmental stresses. This new knowledge will help researchers to design more resilient crops for future climate conditions.
Understanding how plants rapidly respond to stress using SUMO will be of great importance to provide breeders novel targets for improving crop resilience in the face of climate change.
