From: Root lodging is a physical stress that changes gene expression from sucrose accumulation to degradation in sorghum

Fig. 7

Representative genes involved in sugar accumulation or release. a Model of intact sorghum. Sucrose (Suc) is accumulated in the vacuoles or is degraded to glucose (Glc) and fructose (Frc) in the cytosol. These hexoses are stored or used for starch synthesis. Genes for sucrose accumulation were highly expressed in intact stems. b Model of lodged sorghum. Sucrose stored in vacuoles is translocated to other tissues. Sucrose is synthesized from stored starch or hexoses. Genes for release of stored sucrose to other tissues were expressed in the lodged stem. Illustrations on the left show schematically the enzymatic reactions or transport steps involved in sugar accumulation or release. Yellow numbers correspond to the numbers in the tables at right. In these tables, genes within each family with expression levels that changed with lodging (red: significantly higher in intact plants; blue: significantly higher in lodged plants) and genes that were expressed at high levels but not differentially between intact and lodged plants (black) are listed
