The review continues with examples of the application of several of these transformation strategies in the manipulation of secondary metabolism. These are outlined under four subheadings which include developmentally regulated genes, addition of novel genes, down-regulation of specific genes and insertion of regulatory genes. Finally, under concluding remarks, reference is made to the advances achieved in the manipulation ofplant secondary metabolism and how these approaches may impact on this new.enIn Copyrightddc:570
