The main aim of this work was to better understand how the low temperature signal from leaves may affect stress responses in roots, and light conditions modify certain acclimation processes rice plants. Rice plants grown at 27°C were exposed temperatures (12°C) with different intensities, case some groups plants, only received cold, while roots remained control temperature. RNA sequencing focusing on under normal growth found 525 differentially expressed genes comparisons. Exposure led more down-regulated than up-regulated genes. Comparison between leaf-stressed whole cold-treated or revealed that nitrogen metabolism nitric oxide-related signalling, as well phenylpropanoid-related processes, specifically affected. Real-time PCR results COLD1 polyamine oxidase genes, metabolomics targeting hormonal changes phenolic compounds also showed not cold exposure leaves, either alone together but influence
