耐非生物胁迫转基因水稻的培育——现在和未来

Transgenic Rice Breeding for Abiotic Stress Tolerance—Present and Future

摘要:

环境胁迫严重降低了作物产量，日益减少的耕地和膨胀的人口对世界粮食安全造成了威胁。长期以来，改善作物的抗逆性一直是农业生产的主要目标。水稻是重要的粮食作物之一，培育具有抗逆性的水稻品种对全球的粮食生产将产生重要影响。在改善水稻的抗逆性方面，转基因比传统方法更有发展潜力。近年来，已有许多抗逆相关基因转入水稻并获得了一些提高抗逆性的转基因植株，文章重点讨论了耐非生物胁迫转基因水稻的研究进展。

Abstract:

Environmental stresses and the continuing deterioration of arable land，along with an explosive increase in world population, pose serious threats to global agricultural production and food security. Improving the tolerance of the major crop plants to abiotic stresses has been a main goal in agriculture for a long time. As rice is considered one of the major crops, the development of new cultivars with enhanced abiotic stress-tolerance will undoubtedly have an important effect on global food production. The transgenic approach offers an attractive alternative to conventional techniques for the genetic improvement of rice cultivars. In recent years, an array of stress-related genes has already been transferred to rice to improve its resistance against abiotic stresses. Many transgenic rice plants with enhanced abiotic stress-tolerance have been obtained. This article focuses on the progress in the study of abiotic stress tolerance in transgenic rice breeding.
