WebBy using these two approaches, we learned about the virulence spectra of the blast pathogen collections and also how the known blast R genes could be used in subsequent breeding efforts. From these findings, we initiated a marker assisted gene pyramiding effort to bring promising blast resistance genes into backgrounds of adapted 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. foil christmas tree garlandWebJul 22, 2024 · After combining the other studies using different isolates from different years and at least three different rice growing ecological regions (Tian et al., 2016; Dai et al., … foil chubangaWebOct 14, 2024 · In our previous study, we identified multiple major and minor resistance loci in Ziyu44 and suggested that the combination of major and minor resistance on multiple loci is one of the mechanisms underlying the durable resistance of Ziyu44 to rice blast disease ( Zhang et al., 2009; Zhou et al., 2015; Hu et al., 2024; Zhuo et al., 2024 ). foil christmas trees for saleWebMar 25, 2012 · Quantitative trait loci (QTLs) for resistance to rice blast offer a potential source of durable disease resistance in rice.
