2.3.1.146 agriculture even though pinosylvin, due to its high antifungal activity, could offer new possibilities in engineering disease resistance, its synthesis in heterologous plants may be restricted by factors related to 4-coumarate:CoA ligase-substrate specificity, or metabolic channelling. Cotransformation of pinosylvin-forming stilbene synthase and cinnamate-specific 4-coumarate:CoA ligase could offer a feasible tool to avoid these restrictions 660155 2.3.1.146 agriculture the promoter-stilbene synthase construct may be useful for the ablation of pollen formation in coniferous gymnosperms and male sterility may potentially be viewed as a prerequisite for the commercial use of transgenic conifers 676406
