摘　要：

质膜内在蛋白(PIPs)能促进水分及不带电分子的跨膜转运。当植物处于干旱、盐碱、低温和低氧等胁迫条件下, 由于脱水等原因造成植物体内水分平衡被打破, PIPs在维持植物体内水平衡以及促进水分运输过程中起重要作用。本文综述最新关于PIPs在各种逆境条件下作用的研究进展, 以期为PIPs研究提供参考。

Abstract:

Plasma membrane intrinsic proteins (PIPs) can facilitate the transmembrane transportation of water and neutral molecule. When the plant suffers from the drought, salt and/or low temperature stress, the water balance is usually broken by the dehydration. PIPs play an important role in maintaining water balance and facilitating water transport. This paper reviews the latest progress on PIPs under various stress conditions and the provision of references for PIPs study is expected.

Key words: aquaporin; drought; low temperature; salt; water transport
