Durable resistance to rice blast
WebAfter the successful colonization of rice roots by S. indica, both the rice blast disease and bakanae disease were significantly reduced. Interestingly, the purified SiChi could promptly induce rice disease resistance towards M. oryzae and F. moniliforme pathogens when sprayed on rice leaves. 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.
