LEA Proteins and the Evolution of the WHy Domain.

ABSTRACT: The late embryogenesis abundant (LEA) family is composed of a diverse collection of multidomain and multifunctional proteins found in all three domains of the tree of life, but they are particularly common in plants. Most members of the family are known to play an important role in abiotic stress response and stress tolerance in plants but are also part of the plant hypersensitive response to pathogen infection. The mechanistic basis for LEA protein functionality is still poorly understood. The group of LEA 2 proteins harbor one or more copies of a unique domain, the water stress and hypersensitive response (WHy) domain. This domain sequence has recently been identified as a unique open reading frame (ORF) in some bacterial genomes (mostly in the phylum Firmicutes), an
