Genetic Transformation of Wheat Mediated by Agrobacterium tumefaciens.
A rapid Agrobacterium tumefaciens-mediated transformation system for wheat was developed using freshly isolated immature embryos, precultured immature embryos, and embryogenic calli as explants. The explants were inoculated with a disarmed A. tumefaciens strain C58 (ABI) harboring the binary vector pMON18365 containing the [beta]-glucuronidase gene with an intron, and a selectable marker, the n...
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 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 کاملAgrobacterium tumefaciens mediated transformation of Agaricus bisporus
Agrobacterium tumefaciens is known to transfer parts of its tumor-inducing plasmid to filamentous fungi including Agaricus bisporus. We have used this transformation system to transform germinating basidiospores of A. bisporus. Analysis of hygromycin B-resistant clones showed that the T-DNA integrated at random sites and in multiple copies into the host genome. Furthermore we have been able to ...
متن کاملProgress of cereal transformation technology mediated by Agrobacterium tumefaciens
Monocotyledonous plants were believed to be not transformable by the soil bacterium Agrobacterium tumefaciens until two decades ago, although convenient protocols for infection of leaf disks and subsequent regeneration of transgenic plants had been well established in a number of dicotyledonous species by then. This belief was reinforced by the fact that monocotyledons are mostly outside the ho...
