摘要
甘薯(Ipomoea batatas)不仅是重要的粮食作物,也是重要的经济作物和能源作物。近年来,随着分子生物学技术的发展,甘薯中越来越多的抗逆相关基因被挖掘。根据基因作用方式的不同,主要分为两大类:调节基因和功能基因。综述了逆境胁迫下甘薯抗逆相关基因的克隆、功能验证以及外源基因转入甘薯应用等方面的一些最新进展,并对今后的甘薯的抗逆研究提出了展望。
Sweet potato（Ipomoea batatas） is not only an important food crop, but also an important economic crop and energy crop. In recent years, as the develop- ment of molecular biology techniques, more and more abiotic and biotic stress-related genes were discovered in sweet potato. These genes can be divided into two categories： the regulatory genes and the functional genes, according to their different roles in stress pathways. This paper reviews the abiotic and biotic stress-related genes cloning, functional analysis and exogenous genes application in sweet potato, and makes expectation for stress resistance research of sweet potato in the future.
