WebFeb 9, 2009 · Rice blast severely reduces production in both irrigated and water-stressed upland ecosystems of tropical and temperate countries. Nearly 50 blast resistance genes have been identified and some of those are incorporated into several rice cultivars. WebRice resistance against blast, a devastating fungal disease, is typically mediated by nucleotide-binding site leucine-rich repeat (NLR) proteins. Most previous studies focused on individual NLR genes, but single R genes typically confer no durable resistance owing to their narrow resistance spectrum.
