1. Agrobacterium tumefaciens is responsible for causing crown galls , tumorlike growths on plants. 2. Erwin Frink Smith, the crown galls , citrus cankers, and corn and chestnut blight. 3. Ti plasmid DNA in the nuclear DNA of crown gall tissue. 4. Bacteria cause plant diseases including leaf spot and crown galls . 5. Steps can be taken to control crown gall disease and reduce the risk of infection. 6. C58, the first fully sequenced pathovar, was first isolated from a cherry tree crown gall . 7. His most significant work was his study of crown gall -a plant cancer induced by Agrobacterium tumerfaciens. 8. It is also produced by " Agrobacterium " and causes crown gall tumor growth in plants. 9. It showed inhibitory activity against cells of crown gall tumor and human lung, breast and colon carcinomas. 10. The Ribamar team carried out further research on the Agrobacterium tumefaciens pathogen, which causes Crown gall disease.
