Cucumber mosaic virus (CMV) poses a significant threat to pepper production worldwide, underscoring the need for resistant cultivars. Although disease resistance genes can expedite breeding, no CMV resistance gene had been cloned from pepper, leaving its molecular mechanism unknown. Here, we cloned a novel resistance gene, designated qCmr2.1, from the resistant accession C. frutescens cv. PBC688. It encodes a 1244‑amino‑acid TIR‑NB‑LRR protein and shares high sequence homology with the N gene from Nicotiana tabacum and its orthologs.
