"In a more general sense, all the quarter-million plant species— in fact, all species of organisms—are potential donors of genes that can be transferred by genetic engineering into crop species in order to improve their performance. With the insertion of the right snippets of DNA, new strains can be created that are variously cold-hardy, pest-proofed, perennial, fast-growing, highly nutritious, multipurpose, water-conservative, and more easily sowed and harvested. And compared with traditional breeding techniques, genetic engineering is all but instantaneous."
