| Abstract: | Late embryogenesis abundant proteins （LEA proteins） are a group of stress-responsive proteins in higher plants that are induced by environmental stress. These proteins can enhance plant tolerance against environmental stress via stabilizing cell membrane and binding ions. The category and structure of LEA proteins are summarized herein. The researches conducted in recent years are reviewed about the roles of LEA proteins in plant response to drought, low temperature and other environmental stresses. |

| Keywords: | plant resistance late embryogenesis abundant protein |
