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 ]. WebMay 6, 2024 · Marker-assisted selection (MAS) is a highly efficient breeding approach that could offer an opportunity to select the targeted gene rapidly and precisely (Tanksley et al. 1989).It is a promising method to provide broad-spectrum and durable rice blast resistance through gene or QTL pyramiding (Tabien et al. 2002).Recently, the …
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.
WebThe improvement of resistance to blast, a devastating fungal disease of rice, would support the sustainable production of one of the world's staple foods, yet the identification of genes for durable resistance in rice is a challenge owing to their complicated genetic control. Here we show that map-based cloning ofidentifies multiple functional ...
