Plant Genetic Modification

• Agrobacterium-mediated transformation is a common method for plant genetic modification.
• Tumorigenic genes are removed from the bacterium during transformation.
• The binary vector system is a two-plasmid system that is effective for transforming plant cells.
• Leaf pieces, cotyledons, stem segments, callus suspension cultures, and germinating seeds can be used as explants for transformation.
• Viruses have been investigated as vectors for gene transfer in plants, but are not routinely used.
• Biolistics is the most effective and widely used method for generating commercial transgenic crops.
• Physico-chemical uptake of DNA by protoplasts and cells can be used to produce transgenic plants.
• Electroporation can induce pores in the protoplast membrane to allow for DNA uptake.
• T-DNA, Agrobacterium chromosomal virulence genes, and Ti plasmid virulence genes are the genetic elements that constitute the T-DNA transfer machinery.
• An efficient tissue culture system is required for the regeneration of transformant cells.
