Figure 1From: Improving yeast strains using recyclable integration cassettes, for the production of plant terpenoidsThe Mevalonate pathway of GPP and FPP biosynthesis in yeast. The non-boxed rectangles show the points of integration of the introduce plant enzymes producing monoterpenes and sesquiterpenes. The encircled enzymatic steps represent targets of modification. Solid lines represent introduction of extra gene copies (HMG2, IDI1), broken lines show the introduction of a strong inducible promoter in one of two alleles, and in dotted line is the deletion of one allele to generate a haploinsufficient strain.Back to article page
