Most crop plants are sensitive to high salinity and the growth is repressed in saline soil, which is increasing these years. To elucidate the mechanism of salt tolerance of plants, we have isolated PMP3 gene family, which is involved in membrane depolarization in yeast cells, from rice and analyzed the expression and function of rice PMP3 (OsPMP3) genes. We have found that OsPMP3 is also involved in salt tolerance via repressing salt uptake into the cells in rice. We suggest that OsPMP3 genes are good candidates for improving salt tolerance of rice plants using a gene transformation technique.

大多数作物对高盐敏感，在盐碱地上生长受到抑制，近年来盐碱地的数量呈上升趋势。为了阐明植物的耐盐机制，本研究从水稻中分离了与酵母细胞膜去极化相关的PMP3基因家族，并分析了水稻PMP3（OsPMP3）基因的表达和功能。我们发现OsPMP 3还通过抑制水稻细胞对盐的吸收而参与水稻的耐盐性。我们认为OsPMP3基因是利用基因转化技术提高水稻耐盐性的良好候选基因。
