Notícies: Recycle or dispose of defective chloroplast proteins: a question of stress

A team of CRAG scientists has discovered a mechanism that relies on chaperones to 'decide' when to destroy or recycle proteins that become defective in chloroplasts. Chloroplast proteins are necessary for photosynthesis and for the production of many compounds of nutritional and economic interest in plants.

The research, published in the journal "PLoS Genetics", reveals how plants recognize proteins that stop working and how they decide to destroy or repair them depending on the level of stress. This discovery is important for improve plant response to environmental changes and to increase the nutritional quality of plant-derived products.
