Abstract Background Sheath blight (ShB) disease caused by Rhizoctonia solani Kühn, is one of the most economically damaging rice ( Oryza sativa L.) diseases worldwide. There are no known major resistance genes, leaving only partial from small-effect QTL to deploy for cultivar improvement. Many ShB-QTL associated with plant architectural traits detrimental yield, including tall plants, late maturity, or open canopy few procumbent tillers, which confound detection physiological resistance. Results To identify ShB resistance, 417 accessions Rice Diversity Panel 1 (RDP1), developed association mapping studies, were evaluated height and days heading in inoculated field plots Arkansas, USA (AR) Nanning, China (NC). Inoculated greenhouse-grown plants used evaluate using a seedling-stage method eliminate effects tiller (TN) panicle number (PN) per plant. Potted RDP1 TN PN. Genome-wide (GWA) over 3.4 million SNPs identified 21 targeted SNP markers tagged 18 not undesirable architecture traits. Ten among Indica subspecies, ten Japonica subspecies accessions, all accessions. Across QTL, qShB4-1 was previously reported biparental studies qShB9 GWA studies. All 14 PN overlapped 15 total identified. Allele at five co-located indicated that increased does inevitably increase development; fact, four alleles increasing PN, suggesting desirable coupling linked genes. Conclusions Nineteen as containing each subpopulation resistant both AR NC trials. breeders can utilize these develop cultivars enhanced along improved yield potential.

Rice sheath blight (ShB) disease poses a major threat to rice yield throughout the world. However, defense mechanisms against ShB in remain largely unknown. resistance is typical quantitative trait controlled by multiple genes. With rapid development of molecular methods, many loci (QTLs) related agronomic traits, biotic and abiotic stresses, have been identified genome-wide association studies. The interactions between plants pathogens are various plant hormone signaling pathways, pathways synergistically or antagonistically interact with each other, regulating growth as well response.

Abstract Rhizoctonia solani is a devastating soil-borne pathogen that seriously threatens the cultivation of economically important crops. Multiple strains with very broad host range have been identified, but only 1 (AG1-IA, which causes rice sheath blight disease) has examined in detail. Here, we analyzed AG4-HGI 3 originally isolated from Tartary buckwheat (Fagopyrum tataricum), comparable to AG1-IA. Genome comparison reveals abundant pathogenicity genes this strain. We used multiomic approaches improve efficiency screening for disease resistance genes. Transcriptomes plant–fungi interaction identified differentially expressed associated virulence and buckwheat. Integration jasmonate-mediated transcriptome metabolome changes revealed negative regulator jasmonate signaling, cytochrome P450 (FtCYP94C1), as increasing probably via accumulation resistance-related flavonoids. The integration data 320 accessions gene homolog aspartic proteinase (FtASP), peak expression following R. inoculation. FtASP exhibits no activity functions an antibacterial peptide slows fungal growth. This work potential mechanism behind resistance, should accelerate molecular breeding resistant varieties essential

Leaf sheath blight disease (SB) of rice caused by the soil-borne fungus Rhizoctonia solani results in 10-30% global yield loss annually and can reach 50% under severe outbreaks. Many resistance genes receptor-like kinases (RLKs) are recruited early on host plant to respond pathogens. Wall-associated receptor (WAKs), a subfamily kinases, have been shown play role fungal defense. The gene WAK91 (OsWAK91), co-located major SB QTL region chromosome 9, was identified us as candidate defense against blight.

Rice sheath blight (ShB) is a devastating disease that severely threatens rice production worldwide. Induction of cell death represents key step during infection by the ShB pathogen Rhizoctonia solani. Nonetheless, underlying mechanisms remain largely unclear. In present study, we identified transcription factor, OsERF65, negatively regulates resistance to suppressing death. OsERF65 was significantly upregulated R. solani in susceptible cultivar Lemont and highly expressed leaf sheath. Overexpression (OsERF65OE) decreased resistance, while knockout mutant (oserf65) exhibited increased against ShB. The transcriptome assay revealed repressed expression peroxidase genes after infection. antioxidative enzyme activity oserf65 plants but reduced OsERF65OE plants.
