What is the function of Vir C gene of Agrobacterium tumefaciens?

Solution(By Examveda Team)

Transfer of T-DNA is the function of the Vir C gene of Agrobacterium tumefaciens.
Agrobacterium tumefaciens induces tumors in plants by transferring a piece of single-stranded DNA, T-DNA, from its tumor-inducing (Ti) plasmid into plant cells.
The subsequent integration and expression of T-DNA in the plant genome leads to the formation of crown gall tumors.
Vir genes are directly involved in T-DNA cleavage from the Ti plasmid, T-DNA processing, transferring and integration into plant nuclei.
