genetic transformation studies were carried out to standardize a protocol for agrobacterium -mediated genetic transformation of three economically important strawberry (fragaria x ananassa duch) cultivars kurdistan’, camarosa’, and ‘paros’. shoot regeneration frequency 72, 65 and 30% was obtained on ms (1) basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa, kurdistan and paro...

Genetic engineering methods have been used successfully to modify the fatty acid profile of elite Australian germplasm of Brassica napus and B. juncea. Co-suppression plasmids carrying oleate desaturase genes from each species have been constructed and transferred into Australian elite breeding lines of B. napus and B. juncea using Agrobacterium tumifaciens plant-transformation techniques. Modi...

An efficient system was established for high frequency embryogenesis and regeneration of indica rice, Oryza sativa L. cv. MDU 5. Basic media, carbohydrate sources and concentrations, agar concentrations, amino acids, cytokinins and auxins were evaluated in callus induction and regeneration media to establish the most efficient regeneration protocol for MDU 5 indica rice. The optimized callus in...

BACKGROUND & OBJECTIVES Catheter associated urinary tract infections are the second most common nosocomial infections and Pseudomonas aeruginosa is the third most common organism responsible for these infections. In this study P. aeruginosa isolates from catheterized urinary tract infection patients were screened and profiled for the presence of different type of quorum sensing (QS) signal mole...

Rhizobium, Agrobacterium and Allorhizobium are genera within the bacterial family Rhizobiaceae, together with Sinorhizobium. The species of Agrobacterium, Agrobacterium tumefaciens (syn. Agrobacterium radiobacter), Agrobacterium rhizogenes, Agrobacterium rubi and Agrobacterium vitis, together with Allorhizobium undicola, form a monophyletic group with all Rhizobium species, based on comparative...

Agrobacterium: Microbe Wiki http://microbewiki.kenyon.edu/index.php/Agrobacterium This website provides an excellent overview of the genus Agrobacterium. It contains photos and links to additional information. Genome of Agrobacterium tumefaciens http://www.genomenewsnetwork.org/articles/12_01/ A_tumefaciens_genome.shtml A. tumefaciens has been the most widely studied and used Agrobacterium spec...

Non-nodulating Agrobacterium-like strains identified among root nodule isolates of common bean were labeled with gusA, a reporter gene encoding beta-glucuronidase (GUS). Bean plants were then co-inoculated with an infective Rhizobium strain and labeled transconjugants of Agrobacterium-like strains. Blue staining of nodules showed that Agrobacterium-like strains were able to colonize these symbi...

As a special phytopathogen, Agrobacterium tumefaciens infects a wide range of plant hosts and causes plant tumors also known as crown galls. The complexity of Agrobacterium-plant interaction has been studied for several decades. Agrobacterium pathogenicity is largely attributed to its evolved capabilities of precise recognition and response to plant-derived chemical signals. Agrobacterium perce...
