Arabidopsis RPP4 is a member of the RPP5 multigene family of TIR‐NB‐LRR genes and confers downy mildew resistance through multiple signalling components

Abstract
In Arabidopsis, RPP4 confers resistance to Peronospora parasitica (P.p.) races Emoy2 and Emwa1 (downy mildew). We identified RPP4 in Col‐0 as a member of the clustered RPP5 multigene family encoding ...
