The use of wild type pTi as a vector presents the following three problems.

1. Presence of oncogenes (iaaM, iaaH and ipt) in T-DNA, which causes a disorganised growth and a loss of regeneration potentiaLof the cells having T-DNA in their genomes.

2. Their large size makes the handling procedures during cloning tedious and cumbersome.

3. A general lack of unique cloning sites within the T-DNA, which are needed for the insertion of DNA segments to be cloned

In the above mention’s problems, 1 and 3 can removed by disarming and creating MCS, to overcome from 2nd problem need to develop
