Solution and Explanation
Crown gall is a neoplastic disease characterized by tumor-like galls at the crown (base) of stems and roots. Agrobacterium tumefaciens transfers T-DNA from its Ti plasmid into plant cells, incorporating genes for auxin/cytokinin overproduction and opine synthesis, leading to uncontrolled gall growth.
