Abstract:

LEA (late embryogenesis abundant) proteins will be induced in plants under stress conditions. The overexpression of LEA proteins can reduced plant injure by stress. In current paper, the types, features and functions, gene structure, expression and regulation of LEA proteins, and the relationship among LEA gene expression, LEA protein accumulation and plant stress tolerance were summarized.

Key words: LEA proteins; gene expression; stress conditions; stress tolerance
