(a) hy5/35S:BBX31 exhibit constitutive elongated hypocotyl length over increasing fluence of white light. Line graph depicting hypocotyl lengths of Col-0, hy5, 35S:BBX31 and hy5/35S:BBX31 under different fluence of white light (b) Representative images of the seedlings grown in low white light (10 μmolm⁻²s⁻¹) and high white light (90 μmolm⁻²s⁻¹) for 7 days. (c) Quantification of primary root length of 7-day old seedlings of the indicated genotypes in low fluence white light (10 μmolm⁻²s⁻¹) and high fluence white light (90 μmolm⁻²s⁻¹). (d) Principal Component Analysis of metabolite profiles of Col-0 and 35S:BBX31 clustered separately depicting significant variations triggered by an early response of UV-B radiation. (e) Relative levels of key metabolites in Col-0 and 35S:BBX31 Arabidopsis seedlings on 24hr exposure to UV-B radiation exhibit significant variations due to metabolic readjustment. Error bars represent SD of atleast 3 replicates. Asterisks represent statistically significant differences (****p value < 0.0001; *** p value < 0.001, * p value < 0.01) as determined by Student’s t test.
