Abstract

Plants, throughout their life cycle, are exposed to vagaries of biotic and abiotic stresses. To alleviate the stresses, plants have developed different molecular response systems. One such response is the high-level accumulation of Late Embryogenesis Abundant (LEA) proteins, a group of hydrophilic proteins encoded by a set of genes during seed dehydration, at the late stage of embryogenesis. These proteins are reported not just in plants, but also in algae, bacteria, and nematodes. LEA proteins are reported to play a versatile role in stress tolerance. This chapter discusses the classification, distribution, characterization, and functions of LEA proteins and their implications for plant stress tolerance.
