文摘Fusarium head blight(FHB),mainly caused by Fusarium graminearum,is one of the most devastating diseases of wheat worldwide.Identification and validation of major quantitative trait loci(QTLs)for FHB resistance without negative effects on agronomic traits is critical to success in breeding FHB-resistant cultivars.In this study,a stable major QTL on chromosome arm 2DL was identified by evaluating a recombinant inbred line(RIL)population derived from Shi4185×Shijiazhuang 8 in both field and greenhouse experiments.QTL mapping and pedigree analyses indicated that the 2DL QTL is the same as QFhb-2DL previously identified in Ji5265;therefore,it was designated Fhb9.Four kompetitive amplicon sequence polymorphism(KASP)markers were developed based on exome capture sequencing data to enhance marker density in the Fhb9 region,and it was delimited to an interval between single nucleotide polymorphism(SNP)markers KASP-12056(533.8 Mb)and KASP-525(525.9 Mb)explained 26.0-30.1%of the phenotypic variation.Analysis of the geographic distribution of the Fhb9 resistance allele suggests that it originated from the Huang-Huai winter wheat region in China.The very low frequency of Fhb9 in modern Chinese cultivars reveals that it has not been widely deployed in breeding programs.Field and greenhouse evaluations of yield-related traits in near-isogenic lines(NILs)contrasting in Fhb9 alleles reveal that the Fhb9 resistance allele have no adverse effects on these traits.Fhb9 showed an additive effect on enhancing FHB resistance with Fhb1.Therefore,Fhb9 is a valuable major QTL for improving FHB resistance in wheat,and the near-diagnostic markers developed in this study will facilitate its deployment in wheat breeding programs.

文摘OBJECTIVE:To explore the potential molecular mechanism of Qigu capsule(芪骨胶囊,QGC) in the treatment of sarcopenia through network pharmacology and to verify it experimentally.METHODS:The active compounds of QGC and common targets between QGC and sarcopenia were screened from databases.Then the herbs-compounds-targets network,and protein-protein interaction(PPI) network was constructed.Gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed by R software.Next,we used a dexamethasone-induced sarcopenia mouse model to evaluate the anti-sarcopenic mechanism of QGC.RESULTS:A total of 57 common targets of QGC and sarcopenia were obtained.Based on the enrichment analysis of GO and KEGG,we took the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway as a key target to explore the mechanism of QGC on sarcopenia.Animal experiments showed that QGC could increase muscle strength and inhibit muscle fiber atrophy.In the model group,the expression of muscle ring finger-1 and Atrogin-1 were increased,while myosin heavy chain was decreased,QGC treatment reversed these changes.Moreover,compared with the model group,the expressions of pPI3K,p-Akt,p-mammalian target of rapamycin and pForkhead box O3 in the QGC group were all upregulated.CONCLUSION:QGC exerts an anti-sarcopenic effect by activating PI3K/Akt signaling pathway to regulate skeletal muscle protein metabolism.

文摘Arsenic speciation in freshwater fish is crucial for providing meaningful consumption guidelines that allow the public to make informed decisions regarding its consumption.While marine fish have attractedmuch research interest due to their higher arsenic content,research on freshwater fish is limited due to the challenges in quantifying and identifying arsenic species present at trace levels.We describe here a sensitivemethod and its application to the quantification of arsenic species in freshwater fish.Arsenic species from fish tissues were extracted using a methanol/water mixture(1:1 vol.ratio)and ultrasound sonication.Anion-exchange high-performance liquid chromatography(HPLC)enabled separation of arsenobetaine(AsB),inorganic arsenite(iAs^(Ⅲ)),dimethylarsinic acid(DMA),monomethylarsonic acid(MMA),inorganic arsenate(iAs^(Ⅴ)),and three new arsenic species.Inductively coupled plasma mass spectrometry(ICPMS)provided highly sensitive and specific detection of arsenic.A limit of detection of 0.25μg/kg(wet weight fish tissue)was achieved for the five target arsenic species:AsB,iAs^(Ⅲ),DMA,MMA,and iAs^(Ⅴ).A series of experimentswere conducted to ensure the accuracy and validity of the analytical method.The method was successfully applied to the determination of arsenic species in lakewhitefish,northern pike,and walleye,with AsB,DMA,and iAs^(Ⅴ) being frequently detected.Three new arsenic species were detected,but their chromatographic retention times did not match with those of any available arsenic standards.Future research is necessary to elucidate the identity of these new arsenic species detected in freshwater fish.
