Transcription profiling of calcium/calmodulin-binding transcription factors in Arabidopsis

ABSTRACT: Screening of cDNA expression libraries with labelled calmodulin (CaM) as a probe resulted in the isolation of cDNA encoding proteins designated CAMTA (for calmodulin-binding transcription activators). The Arabidopsis genome contains 6 members of this protein family (AtCAMTA1-6) all containing in addition to a defined CaM-binding domain a DNA-binding domain and ankyrin-repeat motifs. RT-PCR analysis revealed that all 6 genes are expressed in all organ throughout plant development. Therefore functional regulation of AtCAMTA proteins is likely mediated by second messengers (e.g. calcium/calmodulin signalling) and protein levels rather than by or in addition to gene expression levels. Based on domain organisation and sequence homologies we identified putative members of this protein family in
