WebFeb 2, 2024 · Durable resistance to rice blast By Guo-Liang Wang, Barbara Valent Crop diseases threaten global food security and sustainable agriculture. The most efficient strategy to prevent disease is to develop crop varieties with durable and broad-spectrum resistance ( 1, 2 ). 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.
