Figure 6

The expression profile of genes encoding enzymes involved in trehalose metabolism associated with SR initiation. (a) Trehalose metabolism covers the conversion of uridine diphosphate-glucose (UDPG) and glucose-6-phosphate (G6P) to glucose molecules, catalyzed by trehalose-6-phosphate synthase (TPS), trehalose-6-phosphatase (TPP) and trehalase (TRE). (b) The expression profile of trehalose related genes. X-axis denotes the stage of SR initiation. FR4 denotes fibrous roots of four-weeks-old plants. FR8, IR8 and SR8 denote fibrous, intermediate, and early storage roots of 8-weeks-old plants. Y-axis denotes gene expression by microarray probe intensity. (c) The hypothetical metabolite concentration based on gene expression profiles during the transition from FR8 to IR8. The color for each enzymatic gene represents the fold change in the expression of IR8 relative to FR8. Blue arrows denote a hypothetical tendency of enzymatic activity in the pathway. Red arrows represent a hypothetical tendency of metabolites level in the pathway.
