Expression levels of genes involved in sucrose metabolism. a Sucrose synthesis. b Sucrose degradation. One arrowhead indicates an irreversible reaction, and double arrowheads indicate a reversible reaction. Colors of arrows and of gene names represent relative gene expression levels: significantly higher in intact plants (red); significantly higher in lodged plants (blue); no significant difference (black). Graphs indicate average numbers of FPKM (fragments per kilobase of exon per million mapped sequence reads) of intact (black) or lodged (gray) plants and standard errors from three individual plants. Green arrow represents the link from other metabolic pathways
