Chlorophyll degradation in leaves of gene-silenced pepper plants. a Phenotypes and b Total chlorophyll contents of leaf discs of the gene-silenced plants in response to high salt stress. Leaf discs from the gene-silenced pepper leaves were floated in different concentrations of NaCl solutions (0, 300, 400, and 500 mM)with continuous fluorescent lighting at 25 °C for 3 days. Error bars represent SD for three biological replicates. Asterisks indicate a significant difference (p < 0.05) compared to TRV2:00 leaves
