Improving 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 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 کاملAgrobacterium tumefaciens mutants affected in attachment to plant cells.
An analysis of Agrobacterium tumefaciens mutants with Tn5 insertions in chromosomal DNA showed that the chromosome of A. tumefaciens codes for a specific ability of this bacterium to attach to plant cells. This ability is associated with tumorigenesis by A. tumefaciens, the ability of avirulent A. tumefaciens to inhibit tumorigenesis, and the ability to adsorb certain phages. A second class of ...
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...
