Researchers at King Abdullah University of Science and Technology (KAUST) have uncovered how plants protect photosynthesis under high temperatures, revealing a pathway that could help guide the development of more resilient crops for desert climates, such as those in Saudi Arabia.  

In a study led by Professor Monika Chodasiewicz, the team identified a previously underappreciated protective mechanism inside chloroplasts, where photosynthesis occurs. When temperatures rise, a chlorophyll-producing protein called protochlorophyllide oxidoreductase reorganizes into small, reversible droplets known as chloroplast stress granules. These structures help protect and restore the plant’s ability to convert sunlight into chemical energy.
