Late embryogenesis abundant proteins

Late embryogenesis abundant proteins (LEA proteins) are proteins in plants, some bacteria, and invertebrates that protect against protein aggregation due to desiccation or osmotic stresses associated with low temperature. LEA proteins were initially discovered accumulating late in embryogenesis of cotton seeds. Originally noticed due to its abundance in seeds and pollens, LEA proteins have been found to protect against desiccation, cold, or high salinity in a variety of organisms, including the bacterium Deinococcus radiodurans, nematode Caenorhabditis elegans, Artemia (brine shrimp), and rotifers.
