4 Lecture 33 of human insulin by bacteria, the f rst commercial achievement of gene cloning, stimulated a new industry for producing gene products for therapeutic uses such as blood clotting factors and growth hormones. The technology to describe cloned genes in terms of nucleotide sequence is available and thus manufactured genes are theoretically feasible. Finally, DNA can be inserted into the DNA of higher plants by various techniques including the gene gun. The most promising vector for dicotyledonous plants has been the tumor-inducing plasmid of Agrobacterium turnefaciens , a bacterium that normally incorporates its DNA in the host as part of the infection process. Even genetic engineering is not new! The story beyond this point is still speculative because agriculturally-useful genes are not in surplus and their expression with foreign genomes is still completely unresolved, although positive results have been achieved. The ability to move new genes into old plants has led to imaginative F ights of fancy: a new range of disease and stress-resistant plants, nitrogen
