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. | Downstream components of the calmodulin signaling pathway in the rice salt stress response revealed by transcriptome profiling and target identification .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Yuenyong et al.

A previous study has revealed that transgenic rice over-expressing the calmodulin gene OsCam1 1 lt br gt LOC_Os03g20370 is more tolerant to salt stress than wild type. To elucidate the role of OsCam1 1 in the salt stress lt br gt response mechanism downstream components of the OsCam1 1-mediated response were identified and investigated lt br gt by transcriptome profiling and target identification. lt br gt Results Transcriptome profiling of transgenic Khao Dawk Mali 105 rice over-expressing OsCam1 1 and wild type rice lt br gt showed that overexpression of OsCam1 1 widely affected the expression of genes involved in several cellular lt br gt processes under salt stress including signaling hormone-mediated regulation transcription lipid metabolism lt br gt carbohydrate metabolism secondary metabolism photosynthesis glycolysis tricarboxylic acid TCA cycle and lt br gt glyoxylate cycle. Under salt stress the photosynthesis rate in
