Comparison of Biochemical Pathways Active Under Low and High Sugar

Caption

When a plant is low on sugar (left), a cascade of molecular interactions degrades (DEG) a protein (W) that turns on fatty acid synthesis (FAS). However, when sugar levels are high (right), key steps in this process are blocked, leaving the W protein intact to start fatty acid (oil) production. KEY: K = KIN10, G = GRIK1, P = phosphoryl group, W = WRINKLED1, FAS = fatty acid synthesis, DEG = degradation, T6P = trehalose 6-phosphate. Faded molecules and pathways are less active than those shown in bold colors.
