Quizplus · Accepted Answer

Agrobacterium, a member of the alphaproteobacteria, is a plant pathogen that transfers a segment of its DNA (called T-DNA) into the genome of host plant cells, causing them to produce compounds to nourish the pathogen. This process is called horizontal gene transfer and allows the pathogen to manipulate plant cell growth and division for its own benefit.
