Abstract

Dominant resistance (R) genes are used extensively by plant breeders to protect their crops against (viral) diseases. The most common class of R genes, containing a nucleotide-binding domain (NB) followed by a leucine-rich repeat (LRR) domain, confers resistance through a gene-for-gene mechanism. Recent developments in the research area of antiviral NB-LRR R genes are discussed. Additionally, a section is dedicated towards the antiviral non-NB-LRR R genes, often underrepresented in reviewing literature. Since these generally do not function according to the gene-for-gene mechanism, they represent a valuable resource for breeders to alleviate some of the disadvantages associated with NB-LRR genes in crops.
