Agrobacterium tumefaciens is a soil bacterium responsible for crown gall disease in plants, causing tumour-like swellings through uncontrolled cell division. It transfers part of its genetic material into plant cells. Scientists later used this natural ability in genetic engineering and plant tissue culture to develop improved crops, disease-resistant varieties and useful phytochemical-producing plants successfully.
