Abstract Background Early seed germination in crops can confer a competitive advantage against weeds and reduce the time to maturation harvest. WRKY transcription factors regulate many aspects of plant development including dormancy germination. Both positive negative regulators have been reported plants such as rice Arabidopsis. Using transient expression system, we previously demonstrated that OsWRKY71 is regulator gibberellin (GA) signaling aleurone cells likely forms “repressosome” complex with other transcriptional repressors. Hence, it has potential impact properties. Results In this study, demonstrate , Group IIa gene, appeared at same seed-bearing plants. Rice mutants lacking seeds embryos germinate earlier than wildtype controls. oswrky71 layers, α-amylase activity was hypersensitive stimulation by GA 3 hyposensitive inhibition abscisic acid (ABA). intact also ABA.
