Annotated Information

Gene Symbol

  • Os02g0664000 <=> OsGPX3,GPX3

Function

  • The OsGPX gene family is induced in response to exogenous H2O2 and cold stress.
  • Silencing the mitochondrial OsGPX3 gene impairs normal plant development and leads to a stress-induced morphogenic response via H2O2 accumulation
  • Post-transcriptional knockdown of OsGPX3 affects root and shoot growth

Expression

  • GPX gene expression is mainly regulated by exogenous H2O2

Subcellular localization

  • Subcellular localization analysis showed that GPX proteins are mainly localized in plant cell organelles

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