activatedCaM/CBP60/SARD1 complex upregulate the transcription of isochorismate synthase
CBP60a bound to activated CaM negatively regulates ICS transcription
Several WRKY transcription factors are known to positively regulate ICS transcription, the Oryza WRKY genes here are orthologs of A. thaliana WRKYs that regulate ICS trancription and the Os orthologs putatively may have the same function.
