| 摘 要： | 草坪草的转基因技术已经有了很大的发展，目前已经在多种草坪草上转入了抗除草剂、抗病虫、抗旱抗盐、抗寒抗热和延长绿期以及抗重金属等外源的功能基因，获得了抗逆性提高的转基因植株。综合分析认为，在抗逆机理研究的基础上选择更关键的抗逆基因进行遗传转化、转化草坪草矮化和养分高效吸收的基因、转基因技术与传统育种方法相结合以及转基因草坪草的安全性评价是将来需要重点展开的研究工作。

| Abstract: | Genetic transformation technology in turfgrasses has greatly developed.Some extrinsic functional genes,including herbicide,disease,insect,drought,salinity,low temperature,high temperature,and/or heavy metal-tolerant genes,had been transformed into various turfgrasses and transgenic plants with enhanced tolerance had also been obtained.Selecting more key genes based on tolerance mechanisms,transformation of the genes about dwarfing turfgrasses and efficiently absorbing nutrients,combining transgenic technology with conventional breeding technology,and assessing security of transgenic turfgrasses are important directions in the future. |
