UV-B exposure modulates the level of free phenolics in Arabidopsis (A) The 14 days old Arabidopsis rosette showed distinct phenotypic changes under UV-B as depicted in pictures. (B) UV-B showed morpho-physiological adaptation, but we focused to investigate the phenolics of plants because of their photoprotective role. (C) GC-MS captured phenolics in Col-0 and Col-0 UV-B. The relative peak abundances of phenolics reveal that the level of phenolic was significantly enhanced under UV-B. Error bars represent the SD of 4 replicates. An unpaired t-test was performed for checking the significance. Asterisks represent statistically significant differences (***P < 0.001, **P < 0.01, *P < 0.05) as determined by t-test
