Abstract: The gene rolB from Agrobacterium rhizogenes Ri T-DNA plays an important role in hairy root induction in transformed plants, characterized by an abundant proliferation of adventitious roots from the site of infection. The sites of rolB gene, the regulation of rolB gene expression in transgenic plants, and the structure and function of Rol B protein were reviewed in this paper.

Key words: Agrobacterium rhizogenes, Ri plasmid, rolB gene

摘要： Ri T-DNA rolB基因是发根农杆菌转化植物的决定因子,rolB基因表达引起转基因植物形成大量毛状根(hairy root)。本文介绍近年来rolB基因的位点、表达与调控及Rol B蛋白结构与功能方面的研究进展。
