Answer 1

Agrobacterium tumefaciens - Tumour

Explanation:

Crown gall disease (tumor formation) is caused by Agrobacterium tumefactions (updated scientific name-Rhizobiumradiobactor) in over 140 dicot species. It's a gram-negative soil bacteria with a rod form. The insertion of a small piece of DNA into the plant cell, known as T-DNA (transfer DNA), which is inserted at a semi-random site into the plant genome, causes symptoms.
