By Glick, Bernard R Todorovic, Biljana; Czarny, Jennifer; Cheng, Zhenyu; Duan, Jin; McConkey, Brendan To date, there has been only limited commercial use of plant growth-promoting bacteria in agriculture, horticulture, and silviculture.
Researchers have uncovered the link between two biochemical pathways that plants use to defend themselves against pathogens â€“ pathways that scientists have long believed worked independently of each other.
Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. It is rod shaped. Symptoms are caused by the insertion of a small segment of DNA into the plant cell. It is an alphaproteobacterium of the family Rhizobiaceae which includes the nitrogen fixing legume symbionts. They are pathogenic and provide no benefit to the plant. It also affects a wide variety of plants. In an economical sense it affects walnuts, grape vines,...
