CaNAC2-silenced pepper plants. (A) The expression of CaNAC2 in gene-silenced pepper (TRV2: CaNAC2) cv P70 and control plants (TRV2:00) were tested at 45 days after inoculation; (B) Effect of ABA application and chilling stress on lipid peroxidation (MDA) content in CaNAC2-silenced pepper seedlings. (C) Phenotypes analysis of the CaNAC2-silenced and non-silenced pepper seedlings under 6°C cold stress for 6 h. (D) Chlorophyll contents of leaf disks. (E) Leaf disks phenotypes. Leaf disks from the gene-silenced plants were floated in 300 mM NaCl solutions for 72 h at 25°C. Bars with different lower case letters indicate significant differences compared to empty vector control leaves (Student’s t-test, p ≤ 0.05).
