Plant DNA Infectious Agents

There has been recent rapid progress in the transformation of plants with foreign DNA, making use either of the natural routes of genetic invasion that viruses and bacteria have developed, or of chemical, mechanical and electrical tricks to make plant protoplast membranes permeable to nucleic acids. Genes integrated into plant virus genomes can be carried systemi­ cally from the initial site of infection into the rest of the plant. Genes placed between the borders of Agrobacterium tumefacie...
