The rice Os05g0187100 was reported as OsHXK7 in 2015 [1] by researchers from Korea.

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

You can also add sub-section(s) at will.
