Transient overexpression of CaLRR-RLK1triggered HR mimic cell death in pepper leaves. a The transcript levels ofCaLRR-RLK1 in pepper leaves detected by qRT-PCR. b Trypan blue and DAB staining in leaves transiently expressing CaLRR-RLK1 at 48 h post infiltration. c Electrolyte leakage from leaf discs of CaLRR-RLK1 transiently overexpressed pepper leaves. d Transcript levels of immunity associated genes were detected in CaLRR-RLK1 transient overexpression pepper leaves by qRT-PCR. In a, c and d, values were the mean ± standard error (n = 6). Asterisks (P < 0.05) indicate significant differences as analyzed by the Student’s t-test
