Broad-spectrum polerovirus resistance conferred by a potato TIR-NLR immune receptor

2026-07-01

Abstract excerpt

Potato leafroll virus (PLRV) is an economically important viral disease of potato ( S. tuberosum ). Genetic resistance to this phloem-limited virus is rare, and no cloned resistance ( R ) genes have been reported. Rl adg confers resistance to PLRV in an Andean potato landrace, LOP-868 (Velásquez et al. 2007). We identified the functional Rl adg gene as a homolog of the tomato TIR-NLR-encoding Bs4 . Rl adg...
