Latest Agrobacterium Stories
Scientists have identified a new mutant plant that accumulates excessive amounts of starch, which could help to boost crop yields and increase the productivity of plants grown for biofuels.
A project to use glowing plants to create sustainable light sources has generated a flurry of interest and financial support on the crowdfunding site Kickstarter.
Those who love gardening, or just enjoy the beauty of plant life, but are unable to do so as a result of hay fever or similar allergic reactions will undoubtedly welcome new research out of Spain that could result in long-lasting, pollen-free plants.
Next week's Journal of Biological Chemistry "Paper of the Week" by Wai Mun Huang and colleagues at the University of Utah Health Sciences Center and the University of Minnesota reveals new insights into the molecular properties of the rod-shaped soil bacterium Agrobacterium tumefaciens, the pathogen responsible for crown gall disease, a tumor-forming infection in plants, such as tomatoes, walnuts, grapes and beets.
Studying self-replicating genetic units, called plasmids, found in one of the world's widest-ranging pathogenic soil bacteria -- the crown-gall-disease-causing microorganism Agrobacterium tumefaciens -- Indiana University biologists are showing how freeloading, mutant derivatives of these plasmids benefit while the virulent, disease-causing plasmids do the heavy-lifting of initiating infection in plant hosts.
SAINT PAUL, Minn., Nov.
Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium.
By Choi, Hyong Woo Lee, Byung Gil; Kim, Nak Hyun; Park, Yong; Lim, Chae Woo; Song, Hyun Kyu; Hwang, Byung Kook Plants elaborate a vast array of enzymes that synthesize defensive secondary metabolites in response to pathogen attack.
By Tuttle, John R Idris, A M; Brown, Judith K; Haigler, Candace H; Robertson, Dominique A silencing vector for cotton (Gossypium hirsutum) was developed from the geminivirus Cotton leaf crumple virus (CLCrV).
By Dan, Yinghui Abstract Browning and necrosis of transformed cells/ tissues, and difficulty to regenerate transgenic plants from the transformed cells/tissues (recalcitrance) are common in Agrobacterium-mediated transformation process in many plant species.
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,...
