Light intensity of 150 vs 38 μmol m ^− 2 s ^− 1 affects the expression profile of genes involved in light, hormone and clock-regulated pathways. Variation in expression of (1a) COL9, (1b) EPR1 and (1c) PIF4 candidate genes; (2a) CIP1, (2b) ARF18, (8.2c) ARR6, (2d) SAUR9 and (2e) LAX2 genes showed variable expression; (3) Regulation in TOC1 gene expression in WT root; (4a) ARR6 expression varied in all genotypes but (4b) CIP1 expression varied only in case of Ler and phyB-5 under 150 vs 38 μmol m ^− 2 s ^− 1 light intensity. qRT-PCR was performed with root samples of 5-days old seedlings. Analysis has been described in the method section
