Downstream components of the calmodulin signaling pathway in the rice salt stress response revealed by transcriptome profiling and target identification.

ABSTRACT:

Background

Calmodulin (CaM) is an important calcium sensor protein that transduces Ca²⁺ signals in plant stress signaling pathways. A previous study has revealed that transgenic rice over-expressing the calmodulin gene OsCam1-1 (LOC_Os03g20370) is more tolerant to salt stress than wild type. To elucidate the role of OsCam1-1 in the salt stress response mechanism, downstream components of the OsCam1-1-mediated response were identified and investigated by transcriptome profiling and target identification.

Results

Transcriptome profiling of transgenic 'Khao Dawk Mali 105' rice over-expressing OsCam1-1 and wild type rice showed that overexpression of OsCam1-1 widely affected the expression of genes involved in several cellular processes under salt stress, including si
