Resumen

Feeding 9 billion people by 2050 is one of the greatest challenges facing our society. Crops are the main

source of food; however, atmospheric events associated with ongoing climate change are severely affecting agricultural

productivity. If this trend continues in the coming years, society will face a serious supply crisis for an exponentially

growing global population. Rising global temperatures, extreme droughts, and increased soil salinity are the main causes

of yield loss in crops. Therefore, developing crop varieties resilient to environmental stress is a top priority to maintain

optimal productivity and ensure future food security. To achieve this, it is essential to understand how plants cope with

extreme stress conditions. One of the earliest cellular responses to stress perception is the formation of cytoplasmic

structures known as stress granules (SGs). SGs are biomolecular condensates composed mainly of RNA and proteins,

assembled through a process called liquid–liquid phase separation (LLPS). Although most current knowledge about their

composition, assembly, and function comes from model organisms such as yeast and animals, recent studies in plants

suggest that SGs could play a central role in plant resilience. This opens the possibility of developing SG-targeted

biotechnological strategies to create more stress-tolerant crops.
