摘要

Agrobacterium genetically transforms plant cells by transferring a single-stranded DNA (ssDNA) copy of the transferred DNA (T-DNA) element, the T-strand, in a complex with Agrobacterium proteins VirD2, bound to the 5' end, and VirE2. VirE2 binds single-stranded nucleic acid cooperatively, fully coating the T-strand, and the protein localizes to the plant cell nucleus when transiently expressed.
