Genetic transformation in plants Agriculture and plant breeding relied solely on the accumulated experience of generations of farmers and breeders that is, on sexual transfer of genes between plant species. However, recent developments in plant molecular biology and genomics now give us access to knowledge and understanding of plant genomes and the possibility of modifying them for the production of a variety of valuable plant species and their products. This article presents an overview of the various powerful technologies for transferring genetic material (DNA) into plants
