Question

With reference to {Agrobacterium tumefaciens mediated plant transformation, match the virulence factors in Group 1 with their protein types in Group 2.} 
 

• A. ( {P - i, Q - ii, R - iv, S - iii} )
• B. ( {P - iii, Q - i, R - ii, S - iv} )
• C. ( {P - ii, Q - iv, R - i, S - iii} )
• D. ( {P - iii, Q - i, R - iv, S - ii} )

Hint:

{Agrobacterium tumefaciens} uses virulence factors to mediate T-DNA transfer into plant cells, a critical process in genetic engineering and plant transformation.

Answer 1

The Correct Option is D

The correct matching of virulence factors in Group 1 with their respective protein types in Group 2 is as follows: 
- P - VirG (iii): VirG is a transcriptional activator involved in regulating the expression of other virulence genes. 
- Q - VirA (i): VirA is a kinase that senses plant-derived signals and activates VirG through phosphorylation. 
- R - VirE (iv): VirE is a single-strand binding protein that stabilizes the transferred DNA (T-DNA) during transformation. 
- S - VirC (ii): VirC is a helicase involved in unwinding the T-DNA strand for transfer to the plant genome. Thus, the correct answer is ( {P - iii, Q - i, R - iv, S - ii} ), corresponding to option (D).
