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 کاملReview of Factors Affecting Organogenesis, Somatic Embryogenesis and Agrobacterium tumefaciens- Mediated Transformation of Strawberry
Standardization of an efficient regeneration system for each strawberry genotype is generally an indispensible pre-requisite for the successful development of transgenic plants. In this paper, we review some key factors affecting the regeneration of strawberry plants via adventitious organogenesis or somatic embryogenesis, such as type of explant, growth regulators or dark/light treatments. Sin...
متن کاملAgrobacterium tumefaciens-mediated transformation of yeast.
Agrobacterium tumefaciens transfers a piece of its Ti plasmid DNA (transferred DNA or T-DNA) into plant cells during crown gall tumorigenesis. A. tumefaciens can transfer its T-DNA to a wide variety of hosts, including both dicotyledonous and monocotyledonous plants. We show that the host range of A. tumefaciens can be extended to include Saccharomyces cerevisiae. Additionally, we demonstrate t...
متن کاملTransformation of Arabidopsis thaliana with Agrobacterium tumefaciens.
Transformed Arabidopsis thaliana plants have been produced by a modified leaf disk transformation-regeneration method. Leaf pieces from sterilely grown plants were precultured for 2 days and inoculated with an Agrobacterium tumefaciens strain containing an avirulent Ti (tumor-inducing) plasmid with a chimeric gene encoding hygromycin resistance. After cocultivation for 2 days, the leaf pieces w...
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 ...
