植物毛状根的诱导及应用

The induction and application of plant hairy roots

发根农杆菌(Agrobacterium rhizogenes)诱导植物细胞的快速生长并分化形成毛状根,具有增长速度快、遗传稳定的特点。植物毛状根作为转基因工具被广泛地应用于次生代谢物的生产,环境污染的治理,以及作物品种改良等方面。本文主要从植物毛状根的诱导以及植物毛状根的应用两方面简要综述。同时对其潜在问题与未来发展前景做以展望,以期为毛状根在牧草方面的研究提供一些借鉴,并为草业科学研究领域提供一种新的技术手段。

Agrobacterium rhizogenes induces the neoplastic growth of plant cells that differentiate to form hairy roots.Hairy roots are characterized with a high growth rate and genetic stability which are widely used as a transgenic tool for the production of secondary metabolites,detoxification of environmental pollutants and breeding of crop species.In the present paper,the induction of hairy roots by A.rhizogenes and the recent development of the plant hairy roots application were reviewed.Meanwhile,the associated potential problems and future development prospects were also discussed.These reviews will provide references for the application of hairy roots in the field of pratacultural science.
