1. Presence of oncogenes (iaaM, iaaH and ipt) in T-DNA,

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.

These three problems have been resolved by deleting
