Agrobacterium genus characteristics
Gram-negative bacteria, plant DNA transfer capability, includes A. tumefaciens and A. rhizogenes.
01
Crown gall disease causative agent
Caused by Agrobacterium tumefaciens, results in tumor-like growths at plant crown.
02
Hairy root disease induction
Induced by Agrobacterium rhizogenes, leads to abnormal root hair proliferation.
