The rice Os05g0187100 was reported as OsHXK7 in 2015 [1] by researchers from Korea.
Contents
Annotated Information
Gene Symbol
- Os05g0187100 <=> OsHXK7,HXK7
Function
- OsHXK7 plays in sugar metabolism and efficient germination by enforcing glycolysis-mediated fermentation in O2-deficient rice.
Phenotypic analysis
- The germination of two null OsHXK7 mutants, oshxk7-1 and oshxk7-2, was affected by O2 deficiency, but overexpression enhanced germination in rice.
Expression
- According to transient expression assays that used the promoter:luciferase fusion construct, OsHXK7 enhanced the glucose (Glc)-dependent repression of a rice a-amylase gene (RAmy3D) in the mesophyll protoplasts of maize.
- the expression of OsHXK7, but not its catalytically inactive alleles, complemented the Arabidopsis glucose insensitive2-1 (gin2-1) mutant, thereby resulting in the wild type characteristics of Glc-dependent repression,seedling development, and plant growth.
- OsHXK7-mediated Glc-dependent repression was abolished in the O2-deficient mesophyll protoplasts of maize.
Evolution
