3.4 DEGs involved in red and blue light signaling
The unigenes corresponding to phytochrome B (PhyB ) were found to be highly up-regulated in red light treatment. Whereas, cryptochrome (Cry2) transcripts were found in high levels under blue light (Figure 5). COP1 expression level was found to be higher in red light treatment with blue light down-regulating its expression. Both the light treatments showed similar trends of COP1 and HY5expression. CK2α and PRR5, which are key regulators in plant circadian rhythms, did not vary markedly in their expression levels between the red and blue light treatments. Flowering locus gene-T (FT ) involved in photoperiodism was highly up-regulated (2,8 log2FC) upon blue light treatment (Figure 5).
