Agrobacterium tumefaciens responses to plant-derived signaling molecules
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...
متن کاملPlant responses to Agrobacterium tumefaciens and crown gall development
Agrobacterium tumefaciens causes crown gall disease on various plant species by introducing its T-DNA into the genome. Therefore, Agrobacterium has been extensively studied both as a pathogen and an important biotechnological tool. The infection process involves the transfer of T-DNA and virulence proteins into the plant cell. At that time the gene expression patterns of host plants differ depe...
متن کاملImproving plant transformation using Agrobacterium tumefaciens.
Here, we report a quick and low-cost method to improve plant transformation using Agrobacterium tumefaciens. This method involves the use of physical wounding, ultrasound, and an increase in exposure time to the bacteria. We show how the transformation rate increased from 0 to 14% when an ultrasound pulse of 10 s was used in conjunction with 96 h of bacterial exposure in Eclipta alba explants.
متن کاملAgrobacterium tumefaciens- mediated Transformation of Plant Cells
Agrobacterium tumefaciens is a Gram-negative soil bacterium that causes plant tumours by transferring a portion of DNA from a resident ‘tumour inducing’ (Ti) plasmid into plant cells where it is integrated into a plant chromosome and expressed. This bacteria’s capacity for DNA transfer is the basis of most current plant genetic engineering and make it a model system for the study of pathogenic ...
متن کاملProteomics of a plant pathogen: Agrobacterium tumefaciens.
Agrobacterium tumefaciens is an important plant pathogen which belongs to the α-proteobacteria. In addition, it has served as the main tool for plant molecular genetics. Here we focus on three major aspects: (i) proteomic mapping, (ii) the use of proteomics for the understanding of the response of A. tumefaciens to changes in environmental conditions and (iii) the analysis of the changes in gen...
