毛状根的研究进展及应用

Research Progress on Hairy Root and its Application

作为一种天然遗传工程菌株,发根农杆菌可侵染160多种植物,使植物产生特殊的形态学变化并诱导植物产生大量的毛状根。由于毛状根可稳产高产的生成大量有重要价值的植物次生代谢物质,近几十年来毛状根系统的研究受到越来越多的关注。简要阐述了发根农杆菌诱导毛状根生成的机理,着重介绍了毛状根培育的研究进展及在生产植物次级代谢产物方面的应用。

As a natural genetically engineered strain, Agrobacterium rhizogenes can infect more than 160 plant spe- cies, which can lead to special morphological changes of plant and induce a lot of hairy roots production. During the past several decades, people pay more and more attention to research work on hairy roots system, because hairy roots can produce a lot of important secondary metaholites. Mechanization of hairy roots production induced by Agrobacteri- um rhizogenes was briefly described in this paper. And the recent progress of hairy roots cultivation and application of secondary metabolites were also emphatically introduced.
