摘要

Plant encounters several abiotic and biotic stresses during their life cycle which effect their growth and development. Some plants can withstand stresses because of the presence of well-equipped defense mechanisms that include proteins and metabolites. One such important protein is Late Embryogenesis Abundant (LEA) that helps plants to withstand against various abiotic stress, including cold, heat, salt, drought and osmotic stresses as well as biotic stress. This review comprehensively compiles the classification, structure and functional roles of various LEA protein families, emphasizing their protective mechanisms for retention of water, stabilization of protein, protection of membrane and reduction of oxidative stress. Moreover, LEA protein was found to be essential part of growth and development such as for seed development and dormancy. Recent findings also showed that the role of LEA proteins in developing climate-resilient crops, prolong the self-life of seeds for seed bank conservation and expand into medicinal as well as pharmaceutical applications due to their special ability to stabilize other biomolecules. This review offers insights into the biotechnological and agricultural uses of LEA proteins, making them viable targets for enhancing environmental adaptation of crops and global food security. This article aligns with SDG 15 (Life on Land) of the UN Agenda for Sustainable Development.
