Question

By which path way the t-DNA transfers to the plant cell from Agrobacterium? ​

Answer 1

Generally, bacterial proteins interacting with the T-DNA are presumed to mediate its nuclear uptake via the importin alpha-mediated import pathway. First, VirD2, attached to the 5′ end of the T-DNA, interacts directly with importin alpha via its NLS sequences and is targeted to the host cell nucleus (10).

Answer 2

Explanation:

The genus Agrobacterium is unique in its ability to conduct interkingdom genetic exchange. Virulent Agrobacterium strains transfer single-strand forms of T-DNA (T-strands) and several Virulence effector proteins through a bacterial type IV secretion system into plant host cells.
