Society for Experimental Biology 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. Researchers from the Max Planck Institute of Molecular Plant Physiology looked for excessive starch accumulators in the model plant Arabidopsis thaliana that had been mutated using Agrobacterium tumefaciens. In one of the mutant plants, the starch granules were...

Kickstarter Support For Sustainable Lighting Using Glowing Plants
2013-05-08 04:44:56

redOrbit Staff & Wire Reports - Your Universe Online 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. With 30 days yet to go, the Glowing Plant initiative has already raised more than a quarter million dollars — far surpassing its initial goal of $65,000 — from more than 4,500 backers, each of which are promised seeds for glowing plants in exchange for their...

Allergy Free Plants On The Horizon?
2012-09-01 07:44:57

redOrbit Staff & Wire Reports - Your Universe Online 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. According to an August 30 statement, researchers from the Instituto de Biología Molecular y Celular de Plantas (IBMCP) and BIOMIVA S.L. were able to alter an ornamental...

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. The bacterium is parasitic: It infects its plant host by entering through...

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. The research confirms that the ability of bacteria to cause disease comes at a...

Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium. A comprehensive comparison of the Agrobacterium sequence information with the genome sequences of other bacteria suggests a general model for how second chromosomes are formed in bacteria.* Agrobacteria are members of the Rhizobiaceae family, which also includes the benign, nitrogen-fixing organisms Rhizobium and Sinorhizobium. Agrobacterium tumefaciens C58 is...

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. Here, we isolated the pathogen-responsive CaMNR1 [menthone: (1)- (3S)-neomenthol reductase] gene, a member of the short-chain dehydrogenase/reductase (SDR) superfamily, from pepper (Capsicum annuum) plants. Gas chromatography-mass spectrometry analysis revealed...

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). The CLCrV coat protein gene was replaced by up to 500 bp of DNA homologous to one of two endogenous genes, the magnesium chelatase subunit I gene (ChlI) or the phytoene desaturase gene (PDS). Cotyledons of cotton cultivar 'Deltapine 5415' bombarded with the modified viral vectors...

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. In addition, most crop transformation methods that use NPTII selection produce a significant number of nontransgenic shoots, called "shoot escapes" even under stringent selection conditions. These common problems of plant...

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,...
