摘要:
水稻是全球最重要的粮食作物之一,而土地盐碱化严重制约着全球水稻的生产发展。水稻对盐胁迫表现出中度敏感,目前大部分学者都将研究重点集中于水稻苗期耐盐性,而缺乏对水稻生殖生长期耐盐表型的鉴定,因而选育全生育期耐盐水稻品种是改良盐碱地的重要途径之一。近年来,利用分子生物学手段已定位大量的水稻耐盐QTL,同时在耐盐水稻新品种选育方面也取得了显著进展。本文综述了水稻耐盐基因组学、表观遗传学、蛋白质组学和代谢组学等方面的最新研究进展,为进一步探索水稻耐盐性的分子机理及培育耐盐水稻品种提供参考依据。

Abstract:
Rice is one of the most important food crops in the world. Since this crop is moderately sensitive to salt stress, land salinization is therefore a factor that restricts the increase of global rice production. At present, most studies focus on the salt tolerance of rice at the seedling stage, whereas identification of salt-tolerant phenotypes during the reproductive growth period of rice is rarely conducted. Breeding for new varieties showing salt-tolerant in lifecycle and its application is one of the optimal ways to improve saline soil. In recent years, a large number of salt-tolerant QTLs in rice have been molecularly identified, and significant progress has been made in breeding of new varieties showing salt tolerant. This article reviews the latest research progress in genomics, epigenetics, proteomics and metabolomics on salt tolerance, and provides a reference for exploring the molecular mechanism of salt tolerance and breeding for salt-tolerant varieties in rice.
