Figure.7 Simultaneous silencing of CaNAC2c andCaNAC2ddid not produce additive decrease in thermotolerance but significantly decreased the resistance of pepper plants to RSI. A. Simultaneous silencing of CaNAC2c and CaNAC2d did not produced additive decrease in thermotolerance of pepper plants. B. Simultaneous silencing of CaNAC2c and CaNAC2d did not produced additive decrease in resistance of pepper plants to RSI at 96 and 192 hpi. C. Simultaneous silencing of CaNAC2c andCaNAC2d did not produced additive decrease in Fv/Fm in pepper plants. D. Simultaneous silencing of CaNAC2c andCaNAC2d did not produced additive decrease in △F/Fm of pepper leaves upon HTS in pepper plants. E. Simultaneous silencing ofCaNAC2c and CaNAC2d did not produced additive increase in disease index of pepper plants upon RSI from 2 to 12 dpi. F. Silencing of CaNAC2d did not significantly downregulated thermotolerance related gene upon HTS and immunity related marker genes upon RSI, but its simultaneously silencing with CaNAC2c significantly decreased the transcription of immunity related marker genes upon RSI, but did not affect the expression of thermotolerance related genes comparing to that by CaNAC2c silencing alone. In D, E and F, data presented are means ± standard error (SE) of four replicates, in D and F, different letters above the bars indicate significant differences among means (P < 0.01), as calculated with Fisher’s protected LSD test.
