WebAug 28, 2010 · Rice blast is one of the most widespread and destructive plant diseases worldwide. Breeders have used disease resistance (R) genes that mediate fungal race-specific ‘gene-for-gene’ resistance to manage rice blast, but the resistance is prone to breakdown due to high pathogenic variability of blast fungus.Panicle blast 1 (Pb1) is a … WebApr 12, 2024 · The Cas9 system for DNA modification has recently been used to enhance disease resistance in rice against rice blast disease caused by M. oryzae [ 6 ], suggesting similar potential for wheat, too. More recently, the RNA editing Cas13 system also provides an avenue to explore to generate Wheat Blast–resistant wheat varieties [ 7 ].
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.
