Figure 7.
The MVA (left) and MEP (right) pathway for rubber biosynthesis. Red indicates up-regulation of gene expression and green indicates down-regulation of gene expression. The dashed line indicates that the exact process is still unclear. HMGCR, hydroxymethylglutaryl-CoA reductase; MVD, diphosphomevalonate decarboxylase; DXS, 1-deoxy-D-xylulose-5-phosphate synthase; IDI, isopentenyl-diphosphate delta-isomerase; FPPS, farnesyl diphosphate synthase; GGPPS, geranylgeranyl diphosphate synthase; ISPH, 4-hydroxy-3-methylbut-2-en-1-yl diphosphate reductase; SRPP, small rubber particle protein; REF, rubber elongation factor.
