The pepper‐specific NLR pair CaNRC8/CaRpi‐blb2a‐mediated HR and resistance and were more tolerant to suppression by the PITG_15 278 effector. (a) Microsynteny of Rpi‐blb2 loci in potato (St), tomato (Sl), and pepper (Ca). Rpi‐blb2 locus and its corresponding orthologs of pepper (CaRpi‐blb2b loci) and tomato (Mi‐1.2 loci) are linked as dotted grey lines. NB‐ARC coding genes are presented as grey arrows, and Rpi‐blb2 orthologs are marked as black arrows. (b) CaRpi‐blb2a‐mediated HR cell death against Avrblb2 was more tolerant to PITG‐15278‐mediated suppression compared to CaNRC8/Rpi‐blb2. Photographs were taken at 4 dpi. (c) Average HR intensities of the presented combinations. Statistical significance of variance was analysed using the F‐test (****P < 0.0001; *P < 0.05). (d) CaNRC8/CaRpi‐blb2a‐mediated resistance was more tolerant to suppression by PITG‐15278‐expression compared to CaNRC8/Rpi‐blb2. (e) Average lesion sizes are presented in a box plot. Statistical significance was analysed using the unpaired t‐test (ns, nonsignificant; ****P < 0.0001).
