高羊茅遗传转化研究进展

高羊茅Festuca arundinacea是一种在世界温带地区广泛种植的很重要的多年生冷季型牧草和草坪草,长期以来其品种改良主要依靠常规育种方法。植物基因工程技术的发展为高羊茅新品种选育提供了一种很有潜力的手段,目前国內外的许多公司和实验室都在利用转基因技术改良谊草种的耐逆性、病虫害和除草剂抗性以及品质等性状。本文从受体材料、转化方法、目标基因、影响因素、转基因遗传等多个方面综述了迄今为止高羊茅遗传转化研究所取得的进展。

Advances in studies on genetic transformation of tall fescue

Tall fescue (Festuca arundinacea) is an important perennial cool-season grass species widely planted for forage and turf purposes in temperate regions throughout the world. For a long time, tall fescue has been improved by traditional breeding. Advances in transgenic technology have provided an effective way for development of new cultivars of tall fescue. At present, studies to improve tolerances to adverse environments, resistances to diseases, pests and herbicides as well as quality traits of this grass species by genetic engineering are being carried out in a lot of companies and laboratories at home and abroad. In this paper, progresses in genetic transformation of tall fescue were reviewed in terms of recipient materials, transformation methods, target genes, influencing factors and transgene inheritance.
