要旨:
Arabidopsis can be stably transformed using Agrobacterium tumefaciens-mediated transfer of T-DNA. A. tumefaciens is a soil-dwelling bacterium that transforms normal plant cells into tumor-forming cells by inserting a piece of bacterial DNA (the transfer, or "T," DNA) into the plant cell genome. The T-DNA, which is flanked by left- and right-border (LB and RB) sequences, resides on a tumor-inducing (Ti) plasmid. The Ti plasmid also carries many of the transfer functions for mobilizing the T-DNA. This article provides a brief discussion of the principles of T-DNA transformation, including consideration of T-DNA vectors and their hosts.
