Arabidopsis thaliana Transcriptome or Gene expression
We identified the role of Arabidopsis thaliana CAMTA5 in root development. The relative expression of CAMTA5 was greater in the root tissue as compared to other tissues of Arabidopsis thaliana. Two independent T-DNA insertion CAMTA5 mutants showed abrupt primary and lateral root development indicating a probable role of CAMTA5 in root architecture. The transcriptome analyses of AtCAMTA5 further strengthened the hypothesis since expression of several genes critical for root development was perturbed in the mutant. Our results indicate that CAMTA5 positively regulate calcium uptake while it negatively regulates nitrate transport in the roots. CAMTA5 also regulates ROS response in the roots as revealed by biochemical analysis and supported by our transcriptome date.
