Expression of OsDof genes from different tissues in two rice cultivars, LD5 and LJ11, under cold treatment. Expression profiling was performed using qRT-PCR assay with rice OsActin1 as an internal standard. Three biological replicates were performed for each sample, each with three technical replicates (Supplemental Table 3). UN: untreated plants grown under natural conditions; CO: cold-treated plants. Treatment was performed under both light and dark conditions. E: seeds; R: roots; S: stems; L: leaves. Color scale indicates relative levels of expression
