| 1 | Quantitative trait loci for Fusarium head blight resistance in wheat cultivars Yangmai 158 and Zhengmai 9023显示文摘Fusarium head blight(FHB)is one of the prevalent fungal diseases of wheat worldwide.Exploring new FHB resistance quantitative trait loci(QTL)in adapted wheat cultivars is a critical step for breeding new FHB-resistant cultivars.In this study,we developed a population of 236 F5:7 recombinant inbred lines(RILs)using two popular Chinese wheat cultivars,Yangmai 158 and Zhengmai 9023,with moderate FHB resistance to identify the QTL for FHB type II resistance.This population was evaluated for percentage of symptomatic spikelets per spike(PSS)using single floret injection in repeated greenhouse experiments.Mean PSSs were 33.2%for Yangmai 158 and 30.3%for Zhengmai 9023.A genetic linkage map of 1002 single nucleotide polymorphisms(SNPs)generated by genotyping-by-sequencing(GBS)was constructed for the RIL population.Six QTL were identified for FHB resistance,and three of them were repeatable in the both experiments.Zhengmai 9023 contributed the resistance allele at one repeatable QTL,designated as Qfhb.7D,whereas Yangmai 158 contributed the resistance alleles at the other two repeatable QTL,Qfhb.3AL and Qfhb.2DS.The additional QTL,Qfhb.4AS was significant in the mean PSS,and Qfhb.2DL and Qfhb.7AS were significant in only one experiment.Replacement of each allele individually at the three repeatable QTL significantly changed PSSs.Qfhb.3AL,Qfhb.2DS,and Qfhb.7D explained 8.35%to 9.89%,5.13%to 7.43%,and 6.15%to 9.32%of the phenotypic variations,respectively.The three repeatable QTL contributed by the two parents were additive and stacking the resistance alleles from all the three repeatable QTL showed the highest level of resistance in the current RIL population.Ten SNPs in the QTL regions of Qfhb.3AL,Qfhb.2DS,and Qfhb.7D were converted into KBioscience competitive allele-specific PCR(KASP)assays.One KASP marker for Qfhb.3AL was validated in a panel of wheat cultivars from China.Some of these KASP markers could be useful for marker-assisted selection to stack these QTL. | Pingping Zhang Chenjin Guo Zhao Liu Amy Bernardo Hongxiang Maa Hongxiang Ma Peng Jiang Guicheng Song Guihua Bai | 2021 | The Crop Journal2021，9，1： | 8 |
| 2 | Lactobacillus plantarum KLDS1.0386 with antioxidant capacity ameliorates the lipopolysaccharide-induced acute liver injury in mice by NF-κB and Nrf2 pathway显示文摘The Lactobacillus is of great interest as a natural antioxidant to ameliorate liver injury for its antioxidant capacity.In a previous experiment,Lactobacillus plantarum KLDS 1.0386 was excellent in adhesion and anti-inflammation.This research assessed the antioxidant capacity of L.plantarum KLDS 1.0386 and how it ameliorates the LPS-induced acute liver injury.In vitro results showed that L.plantarum KLDS 1.0386 had potential antioxidant capacity with 27 genes,and it had better capacities in hydroxyl radicals scavenging and lipid antioxidant than the reference strain L.plantarum WCFS1 (P < 0.05).In vivo results,L.plantarum KLDS 1.0386 significantly reduced hepatic tissue injury,pro-inflammatory cytokines (TNF-α,IL-6),myeloperoxidase (MPO) activities and biochemical indicators of hepatotoxicity (ALT,AST,ALP) (P < 0.05),compared with the LPS-treated mice.Moreover,L.plantarum KLDS 1.0386 increased the relative abundance of the genera,including Lachnospiraceae_NK4A136_group,Muribaculaceae and Alistipes,which significantly increased the level of acetic acid and butyric acid (P < 0.05).The results also showed L.plantarum KLDS 1.0386 significantly adjusted the expression of HO-1,NQO1,CAT,NF-κB,TLR4 and IκB-α in the liver (P < 0.05).Overall,these results indicated that L.plantarum KLDS 1.0386 had great functionality in reducing LPS-induced acute liver injury. | Jiahuan Dong Lijun Ping Qinggang Xie Deyu Liu Li Zhao Smith Etareri Evivie Zhongjiang Wang Bailiang Li Guicheng Huo | 2022 | Food Bioscience2022，47，3： | 2 |
| 3 | Specific Regulation of m^(6)A by SRSF7 Promotes the Progression of Glioblastoma显示文摘Serine/arginine-rich splicing factor 7(SRSF7),a known splicing factor,has been revealed to play oncogenic roles in multiple cancers.However,the mechanisms underlying its oncogenic roles have not been well addressed.Here,based on N6-methyladenosine(m^(6)A)co-methylation network analysis across diverse cell lines,we find that the gene expression of SRSF7 is positively correlated with glioblastoma(GBM)cell-specific m^(6)A methylation.We then indicate that SRSF7 is a novel m^(6)A regulator,which specifically facilitates the m^(6)A methylation near its binding sites on the mRNAs involved in cell proliferation and migration,through recruiting the methyltransferase complex.Moreover,SRSF7 promotes the proliferation and migration of GBM cells largely dependent on the presence of the m^(6)A methyltransferase.The two m^(6)A sites on the mRNA for PDZ-binding kinase(PBK)are regulated by SRSF7 and partially mediate the effects of SRSF7 in GBM cells through recognition by insulin-like growth factor 2 mRNA-binding protein 2(IGF2BP2).Together,our discovery reveals a novel role of SRSF7 in regulating m^(6)A and validates the presence and functional importance of temporal-and spatial-specific regulation of m^(6)A mediated by RNA-binding proteins(RBPs). | Yixian Cun Sanqi An Haiqing Zheng Jing Lan Wenfang Chen Wanjun Luo Chengguo Yao Xincheng Li Xiang Huang Xiang Sun Zehong Wu Yameng Hu Ziwen Li Shuxia Zhang Geyan Wu Meisongzhu Yang Miaoling Tang Ruyuan Yu Xinyi Liao Guicheng Gao Wei Zhao Jinkai Wang Jun Li | 2023 | Genomics, Proteomics & Bioinformatics2023，21，4： | 1 |
| 4 | Exact simulation for direction-dependent large elastic strain responses of soft fibre-reinforced composites显示文摘An explicit form of the elastic strain-energy function for direction-dependent large elastic strain behaviors of soft fiber-reinforced composites is first presented based upon a decoupled approach for simulating complex nonlinear coupling effects.From this form,the exact closed-form solutions are then obtained for the uniaxial tension responses in the fiber and cross-fiber directions.With such exact solutions,the issue of simultaneously simulating strongly coupling nonlinear responses in the fiber and cross-fiber directions may be reduced to the issue of separately treating each decoupled uniaxial stress-strain response,thus bypassing usual complexities and uncertainties involved in identifying a large number of strongly coupled adjustable parameters.The numerical examples given are in good agreement with the experimental data for large strain responses. | Huifeng XI Guicheng ZHAO OBRUHNS Siyu WANG Heng XIAO | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，9： | 0 |
| 5 | Performance enhancement of ultrasonic transducer made of textured PNN-PZT ceramic显示文摘In this paper,0.36Pb(Ni_(1/3)Nb_(2/3))O_(3)-0.24PbZrO3-0.40PbTiO_(3)(PNN-PZT)ceramic was prepared,and texture engineering was performed on this PNN-PZT ceramic to improve its electromechanical properties and temperature stability.Single element ultra-sonic transducers were prepared using PNN-PZT,PNN-PZT textured ceramics,and their performance were evaluated and com-pared using a PZT-5H ceramic based transducer as the benchmark.It is shown that the sensitivity and bandwidth of the PNN-PZT textured ceramic-based transducer are much superior to regular PNN-PZT ceramic and PZT-5H ceramic based transducers. | Lang Bian Ke Zhu Qian Wang Jinpeng Ma Jinhui Fan Xudong Qi Guicheng Jiang Bo Zhao Rui Zhang Bin Yang Wenwu Cao | 2022 | Journal of Advanced Dielectrics2022，12，4： | 0 |
| 6 | The ecological response of natural phytoplankton population and related metabolic rates to future ocean acidification显示文摘Ocean acidifi cation(OA)and global warming-induced water column stratification can signifi cantly alter phytoplankton-related biological activity in the marine ecosystem.Yet how these changes may play out in the tropical Indian Ocean remains unclear.This study investigated the ecological and metabolic responses of the different phytoplankton functional groups to elevated CO_(2) partial pressure and nitrate deficiency in two different environments of the eastern Indian Ocean(EIO).It is revealed that phytoplankton growth and metabolic rates are more sensitive to inorganic nutrients rather than CO_(2).The combined interactive effects of OA and N-limitation on phytoplankton populations are functional groupspecific.In particular,the abundance and calcification rate of calcifying coccolithophores are expected to be enhanced in the future EIO.The underlying mechanisms for this enhancement may be ascribed to coccolithophore’s lower carbon concentrating mechanisms(CCMs)efficiency and OA-induced[HCO^(-)_(3)]increase.In comparison,the abundance of non-calcifying microphytoplankton(e.g.,diatoms and dinoflagellates)and primary productivity would be inhibited under those conditions.Diff erent from previous laboratory experiments,interspecifi c competition for resources would be an important consideration in the natural phytoplankton populations.These combined factors would roughly determine calcifying coccolithophores as“winners”and non-calcifying microphytoplankton as“losers”in the future ocean scenario.Due to the large species-specific differences in phytoplankton sensitivity to OA,comprehensive investigations on oceanic phytoplankton communities are essential to precisely predict phytoplankton ecophysiological response to ocean acidification. | Haijiao LIU Yuying ZHAO Chao WU Wenzhe XU Xiaodong ZHANG Guicheng ZHANG Satheeswaran THANGARAJ Jun SUN | 2022 | Journal of Oceanology and Limnology2022，40，3： | 0 |
