Suppression of CaNAC46 leads to salt and drought sensitivity in pepper. The role of CaNAC46 for salt and drought sensitivity was assessed by VIGS. A The TRV2-CaNAC46 and WT plants were subjected to drought stress by dehydration and salinity stress by watering with a 200 mM NaCl solution for 3 weeks. B DAB staining was in TRV2-CaNAC46 and WT leaves than in WT leaves after for 3 weeks of the salt and drought treatments. C The MDA content of TRV2-CaNAC46 and WT plants was measured under drought and salinity stresses. D The expression levels of stress-responsive genes were in examined by qRT-PCR analyses the WT and TRV2-CaNAC46 plants before and after the abiotic stress treatments. Three independent biological experiments were performed. Superscript letters indicate significant differences (P < 0.05)
