physiological function |
hexokinase-7 enhances the glucose-dependent repression of rice alpha-amylase gene RAmy3D in the mesophyll protoplasts of maize, but its catalytically inactive mutant alleles do not. The expression of hexokinase-7, but not its catalytically inactive alleles, complements the Arabidopsis thaliana glucose insensitive gin2-1 mutant, thereby resulting in wild type characteristics of glucose-dependent repression, seedling development, and plant growth. Hexokinase-7-mediated glucose-dependent repression is abolished in the O2-deficient mesophyll protoplasts of maize. Hexokinase-7 functions in sugar signaling via a glycolysis-dependent manner under normal conditions, but its signaling role is suppressed when O2 is deficient. The germination of two hexokinase-7 null OsHXK7 mutants is affected by O2 deficiency, but overexpression enhances germination in rice |
