AT1G72910, AT1G72940, and ADR1-LIKE 2 are important for plant immunity. (a) Expression of group 1 NLR genes in WT plants in response to flg22 treatment, (b) bacterial inoculation, and (c) exogenous SA treatment. (d) Decrease in AT1G72910, AT1G72940, and ADR1-LIKE 2 transcript levels in upf1/3 mutants by darkness at 16 °C. L: light, D: dark. Increased susceptibility to bacterial pathogen Pst DC3000 (e) and decreased PR1 mRNA levels (f) seen in at1g72910, at1g72940, and adr1-like 2 mutants at 16 °C. eds1 and sid2 mutants were used as positive controls. dpi: days post-inoculation. Letters indicate significant difference from one-way ANOVA followed by Tukey’s range tests (p < 0.05) *: p < 0.05; **: p < 0.01, ***: p ≤ 0.001; ns: not significant.
