1A Collinearity-Incorporating Homology Inference Strategy for Connecting Emerging Assemblies in the Triticeae Tribe as a Pilot Practice in the Plant Pangenomic Era显示文摘Plant genome sequencing has dramatically increased,and some species even have multiple high-quality reference versions.Demands for clade-specific homology inference and analysis have increased in the pangenomic era.Here we present a novel method,GeneTribe(http://gffzz6c7fcf032cb94ff5sx60popf9w50c69f6.ffgz.tsg.suse.edu.cn/genetribe/),for homology inference among genetically similar genomes that incorporates gene collinearity and shows bet-ter performance than traditional sequence-similarity-based methods in terms of accuracy and scalability.The Triticeae tribe is a typical allopolyploid-rich clade with complex species relationships that includes many important crops,such as wheat,barley,and rye.We built Triticeae-GeneTribe(http://gffzzaeec8df70e7c4b21hx60popf9w50c69f6.ffgz.tsg.suse.edu.cn/TGT/),a homology database,by integrating 12 Triticeae genomes and 3 outgroup model genomes and implemented versatile analysis and visualization functions.With macrocollinearity analysis,we were able to construct a refined model illustrating the structural rearrangements of the 4A-5A-7B chromosomes in wheat as two major translocation events.With collinearity analysis at both the macro-and microscale,we illustrated the complex evolutionary history of homologs of the wheat vernalization gene Vm2,which evolved as a combined result of genome translocation,duplication,and polyploidization and gene loss events.Our work provides a useful practice for connecting emerging genome assemblies,with awareness of the extensive polyploidy in plants,and will help researchers efficiently exploit genome sequence re-sources.Yongming Chen Wanjun Song Xiaoming Xie Zihao Wang Panfeng Guan Huiru Peng Yuannian Jiao Zhongfu Ni Qixin Sun Weilong Guo 2020Molecular Plant2020,13,12:14
2Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world.Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong 2022Science China(Life Sciences)2022,65,9:9
3WheatOmics:A platform combining multiple omics data to accelerate functional genomics studies in wheat显示文摘Dear Editor,Mold-breaking progress in whole-genome sequencing and rapid accumulation of multi-omics data have revolutionized the research strategies of functional genomics in wheat(Wang et al.,2018).However,how to access these vast multi-omics data and to extract key information on genes of in-terest,is still challenging for most wet-lab or field wheat re-searchers who have little bioinformatic experiences and cannot access the expensive computational resources.Here,we pre-sent WheatOmics(http://gffzz513af15b15bc4712hx60popf9w50c69f6.ffgz.tsg.suse.edu.cn/,previously designated as Triticeae Multi-omics Center,http://gffzz601e21d286504235hx60popf9w50c69f6.ffgz.tsg.suse.edu.cn/),a free,web-accessible,and user-friendly platform.WheatOmics not only empowers the effective access to the visualized multi-omics data of user-interested genes but also offers several distinctive and practical toolkits that can ease almost every aspect of wheat functional genomics studies(Figure 1A).Shengwei Ma Meng Wang Jianhui Wu Weilong Guo Yongming Chen Guangwei Li Yanpeng Wang Weiming Shi Guangmin Xia Daolin FU Zhensheng Kang Fei Ni 2021Molecular Plant2021,14,12:9
4A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004).Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni 2022Molecular Plant2022,15,3:8
5Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants.Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni 2021Molecular Plant2021,14,9:4
6Efficacy and safety of anlotinib plus S-1as thirdly-line or later-line treatmentin advanced non-small cell lung cancer显示文摘Objective Anlotinib,an oral vascular endothelial growth factor receptor 2(VEGFR2)inhibitor,has confirmed antitumor activity in lung cancer in both in vitro and in vivo assays,and has been recommended as third-line treatment agent in non-oncogene driven non-small cell lung cancer(NSCLC).This prospective study aimed to investigate the efficacy and safety of anlotinib plus S-1 for third-or later-line treatment in patients with advanced NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC,and documented disease progression following second-line chemotherapy,and/or epidermal growth factor receptor-tyrosine kinase inhibitor(EGFR-TKI)treatment were enrolled in this study.The patients were treated anlotinib(8 mg daily d 1–14)and S-1(60 mg/m^2 d 1–14)and the treatment was repeated every 3 weeks.Treatment was continued until disease progression or unacceptable toxicity occurred.The objective response rate(ORR),disease control rate(DCR),progression-free survival(PFS),and adverse events(AEs)were reviewed and evaluated.Results Forty-one patients were enrolled in the study between June 2018 and December 2018.The total ORR and DCR were 26.8%and 80.5%,respectively.The median PFS was 5.2 months[95%confidence interval(CI),3.9 to 6.6 months].In the univariate analysis,there was a significant difference in the median PFS between patients with brain metastases and those without brain metastases(4.8 months vs 5.9 months,respectively;P=0.039).The Eastern Cooperative Oncology Group(ECOG)performance status(P=0.002),lines of therapy(P=0.015),and therapeutic evaluation(P=0.014)were independent factors that influenced PFS.The most common AEs were hypertension,proteinuria,myelosuppression,gastrointestinal reactions,fatigue,and mucositis.Conclusion Anlotinib plus S-1 is an effective and safe regimen for advanced NSCLC as third-or later-line therapy.Heng Cao Kai Liang Peng Liu Jing Wang Yuanyuan Ji Lujuan Xu Weilong Wu Shengnan Guo Xuekun Song Yonggui Hong 2020Oncology and Translational Medicine2020,6,1:4
7A wheat integrative regulatory network from large-scale complementary functional datasets enables trait-associated gene discovery for crop improvement显示文摘Gene regulation is central to all aspects of organism growth,and understanding it using large-scale functional datasets can provide a whole view of biological processes controlling complex phenotypic traits in crops.However,the connection between massive functional datasets and trait-associated gene discovery for crop improvement is still lacking.In this study,we constructed a wheat integrative gene regulatory network(wGRN)by combining an updated genome annotation and diverse complementary functional datasets,including gene expression,sequence motif,transcription factor(TF)binding,chromatin accessibility,and evolutionarily conserved regulation.wGRN contains 7.2 million genome-wide interactions covering 5947 TFs and 127439 target genes,which were further verified using known regulatory relationships,condition-specific expression,gene functional information,and experiments.We used wGRN to assign genome-wide genes to 3891 specific biological pathways and accurately prioritize candidate genes associated with complex phenotypic traits in genome-wide association studies.In addition,wGRN was used to enhance the interpretation of a spike temporal transcriptome dataset to construct high-resolution networks.We further unveiled novel regulators that enhance the power of spike phenotypic trait prediction using machine learning and contribute to the spike phenotypic differences among modern wheat accessions.Finally,we developed an interactive webserver,wGRN(http://gffzzaeec8df70e7c4b21hx60popf9w50c69f6.ffgz.tsg.suse.edu.cn/wGRN),for the community to explore gene regulation and discover trait-associated genes.Collectively,this community resource establishes the foundation for using large-scale functional datasets to guide trait-associated gene discovery for crop improvement.Yongming Chen Yiwen Guo Panfeng Guan Yongfa Wang Xiaobo Wang Zihao Wang Zhen Qin Shengwei Ma Mingming Xin Zhaorong Hu Yingyin Yao Zhongfu Ni Qixin Sun Weilong Guo Huiru Peng 2023Molecular Plant2023,16,2:1
8TaMADS29 interacts with TaNF-YB1 to synergistically regulate early grain development in bread wheat显示文摘Grain development is a crucial determinant of yield and quality in bread wheat(Triticum aestivum L.).However,the regulatory mechanisms underlying wheat grain development remain elusive.Here we report how Ta MADS29 interacts with Ta NF-YB1 to synergistically regulate early grain development in bread wheat.The tamads29 mutants generated by CRISPR/Cas9 exhibited severe grain filling deficiency,coupled with excessive accumulation of reactive oxygen species(ROS)and abnormal programmed cell death that occurred in early developing grains,while overexpression of Ta MADS29 increased grain width and1,000-kernel weight.Further analysis revealed that Ta MADS29 interacted directly with Ta NF-YB1;null mutation in Ta NF-YB1caused grain developmental deficiency similar to tamads29 mutants.The regulatory complex composed of Ta MADS29 and Ta NF-YB1 exercises its possible function that inhibits the excessive accumulation of ROS by regulating the genes involved in chloroplast development and photosynthesis in early developing wheat grains and prevents nucellar projection degradation and endosperm cell death,facilitating transportation of nutrients into the endosperm and wholly filling of developing grains.Collectively,our work not only discloses the molecular mechanism of MADS-box and NF-Y TFs in facilitating bread wheat grain development,but also indicates that caryopsis chloroplast might be a central regulator of grain development rather than merely a photosynthesis organelle.More importantly,our work offers an innovative way to breed high-yield wheat cultivars by controlling the ROS level in developing grains.Guoyu Liu Runqi Zhang Sen Li Rehmat Ullah Fengping Yang Zihao Wang Weilong Guo Mingshan You Baoyun Li Chaojie Xie Liangsheng Wang Jie Liu Zhongfu Ni Qixin Sun Rongqi Liang 2023Science China(Life Sciences)2023,66,7:1

12HITAC-seq enables high-throughput cost-effective sequencing of plasmids and DNA fragments with identity显示文摘DNA sequencing is vital for many aspects of biological research and diagnostics. Despite the development of second and third generation sequencing technologies, Sanger sequencing has long been the only choice when required to precisely track each sequenced plasmids or DNA fragments. Here, we report a complete set of novel barcoding and assembling system, Highly-parallel Indexed Tagmentation-reads Assembled Consensus sequencing(HITAC-seq), that could massively sequence and track the identities of each individual sequencing sample. With the cost of much less than that of single read of Sanger sequencing,HITAC-seq can generate high-quality contiguous sequences of up to 10 kilobases or longer. The capability of HITAC-seq was confirmed through large-scale sequencing of thousands of plasmid clones and hundreds of amplicon fragments using approximately 100 pg of input DNAs. Due to its long synthetic length, HITACseq was effective in detecting relatively large structural variations, as demonstrated by the identification of a~1.3 kb Copia retrotransposon insertion in the upstream of a likely maize domestication gene. Besides being a practical alternative to traditional Sanger sequencing, HITAC-seq is suitable for many highthroughput sequencing and genotyping applications.Xiang Gao Weipeng Mo Junpeng Shi Ning Song Pei Liang Jian Chen Yiting Shi Weilong Guo Xinchen Li Xiaohong Yang Beibei Xin Haiming Zhao Weibin Song Jinsheng Lai 2021Journal of Genetics and Genomics2021,48,8:0
13Nanodiamonds decorated yolk-shell ZnFe_(2)O_(4) sphere as magnetically separable and recyclable composite for boosting antibiotic degradation performance显示文摘Photocatalysis is an environmentally friendly and energy-saving technology, which can effectively remove persistent dangerous pollutants in the water. Pitifully, optical absorption capacity and carrier separation have become major bottlenecks for marvelous photocatalytic performance of photocatalysts.Herein, to address these issue, Nanodiamonds/yolk-shell ZnFe_(2)O_(4) spheres(NDs/ZFO) nanocomposites were successfully constructed via a facile two-step of solvothermal and calcination methods. The synthesized optimal NDs/ZFO-10 nanocomposite exhibits superior photocatalytic degradation activity of antibiotic under visible light, approximately 85% of the total tetracycline(TC) is degraded, and this photocatalyst shows durable cycling stability. This stems from two aspects of refinement: improvement of light absorption capacity and photo-induced charges migration and separation. In addition, the NDs/ZFO composite photocatalyst features excellent magnetic recovery capability, facilitating the recovery of photocatalyst in industry. This study opens a new chapter in the combination of NDs with magnetic materials, and deepens the understanding of the application of NDs modified composite photocatalysts.Jingjing Pan Haoran Sun Keyi Chen Yuhao Zhang Pengnian Shan Weilong Shi Feng Guo 2023Chinese Journal of Chemical Engineering2023,54,2:0
14Highly efficient visible/near-infrared light photocatalytic degradation of antibiotic wastewater over 3D yolk-shell ZnFe_(2)O_(4)supported 0D carbon dots with up-conversion property显示文摘The development of effective visible and near-infrared photocatalysts is highly promising in the current field of photocatalysis.Herein,carbon dots/ZnFe_(2)O_(4)(CDs/ZFO)with coating zero dimensional(0D)CDs on the surface of three dimensional(3D)yolk-shell ZFO spheres was designed and synthesized via a selftemplated solvothermal method.The as-prepared CDs/ZFO composites displayed outstanding visible and near-infrared photocatalytic degradation activity of tetracycline(TC),and the optimal 3%CDs/ZFO sample with loading 3%(mass)CDs displayed the highest photocatalytic TC degradation ability under visible light(79.5%within 120 min)and near-infrared light(41%within 120 min).The enhancement of photocatalytic activity for CDs/ZFO composite is mainly ascribed to the fact that 0D/3D yolk-shell CDs/ZFO structure not only effectively reflect the incident light to increase the utilization efficiency of solar light,but also utilize the up-conversion photoluminescence and electronic conductivity properties of CDs to broaden sunlight absorption range and promote separation and transfer of electron-hole pairs.Weilong Shi Jie Gao Haoran Sun Zhongyi Liu Feng Guo Lijing Wang 2022Chinese Journal of Chemical Engineering2022,35,9:0
15Genome-wide linkage mapping of QTL for root hair length in a Chinese common wheat population显示文摘Root hairs are fast growing,ephemeral tubular extensions of the root epidermis that aid nutrient and water uptake.The aim of the present study was to identify QTL for root hair length(RHL)using 227 F8 recombinant inbred lines(RILs)derived from a cross of Zhou 8425 B(Z8425 B)and Chinese Spring(CS),and to develop convenient molecular markers for markerassisted breeding in wheat.Analysis of variance of root hair length showed significant differences(P<0.01)among RILs.The genetic map for QTL analysis consisted of 3389 unique SNP markers.Using composite interval mapping,four major QTL(LOD>2.5)for RHL were identified on chromosomes 1 B(2),2 D and 6 D and four putative QTL(2≤LOD≤2.5)were detected on chromosomes 1 A,3 A,6 B,and 7 B,explaining 3.32%–6.52%of the phenotypic variance.The positive alleles for increased RHL of QTL on chromosomes 2 D,6 B and 6 D(QRhl.cau-2 D,q Rhl.cau-6 B,and QRhl.cau-6 D)were contributed by Z8425 B,and CS contributed positive QTL alleles on chromosomes 1 A(q Rhl.cau-1 A),1 B(QRhl.cau-1 B.1 and QRhl.cau-1 B.2),3 A(q Rhl.cau-3 A)and 7 B(q Rhl.cau-7 B).STARP markers were developed for QRhl.cau-1 B.1,QRhl.cau-2 D,QRhl.cau-6 D,and q Rhl.cau-7 B.Haplotype and association analysis indicated that the positive allele of QRhl.cau-6 D had been strongly selected in Chinese wheat breeding programs.Collectively,the identified QTL for root hair length are likely to be useful for marker-assisted selection.Feng Huang Zhaoyan Chen Dejie Du Panfeng Guan Lingling Chai Weilong Guo Zhaorong Hu Mingming Xin Huiru Peng Yingyin Yao Zhongfu Ni 2020The Crop Journal2020,8,6:0
16Deciphering the evolution and complexity of wheat germplasm from a genomic perspective显示文摘Bread wheat provides an essential fraction of the daily calorific intake for humanity.Due to its huge and complex genome,progress in studying on the wheat genome is substantially trailed behind those of the other two major crops,rice and maize,for at least a decade.With rapid advances in genome assembling and reduced cost of high-throughput sequencing,emerging de novo genome assemblies of wheat and whole-genome sequencing data are leading to a paradigm shift in wheat research.Here,we review recent progress in dissecting the complex genome and germplasm evolution of wheat since the release of the first high-quality wheat genome.New insights have been gained in the evolution of wheat germplasm during domestication and modern breeding progress,genomic variations at multiple scales contributing to the diversity of wheat germplasm,and complex transcriptional and epigenetic regulations of functional genes in polyploid wheat.Genomics databases and bioinformatics tools meeting the urgent needs of wheat ge-nomics research are also summarized.The ever-increasing omics data,along with advanced tools and well-structured databases,are expected to accelerate deciphering the germplasm and gene resources in wheat for future breeding advances.Zihao Wang Lingfeng Miao Yongming Chen Huiru Peng Zhongfu Ni Qixin Sun Weilong Guo 2023Journal of Genetics and Genomics2023,50,11:0
17TaACTIN7-D regulates plant height and grain shape in bread wheat显示文摘Exploitation of new gene resources and genetic networks contributing to the control of crop yield-related traits,such as plant height,grain size,and shape,may enable us to breed modern high-yielding wheat varieties through molecular methods.In this study,via ethylmethanesulfonate mutagenesis,we identify a wheat mutant plant,mu-597,that shows semi-dwarf plant architecture and round grain shape.Through bulked segregant RNA-seq and map-based cloning,the causal gene for the semi-dwarf phenotype of mu-597 is located.We find that a single-base mutation in the coding region of TaACTIN7-D(TaACT7-D),leading to a Gly-to-Ser(G65S)amino acid mutation at the 65th residue of the deduced TaACT7-D protein,can explain the semi-dwarfism and round grain shape of mu-597.Further evidence shows that the G65S mutation in TaACT7-D hinders the polymerization of actin from monomeric(G-actin)to filamentous(F-actin)status while attenuates wheat responses to multiple phytohormones,including brassinosteroids,auxin,and gibberellin.Together,these findings not only define a new semi-dwarfing gene resource that can be potentially used to design plant height and grain shape of bread wheat but also establish a direct link between actin structure modulation and phytohormone signal transduction.Xiongtao Li Beilu Cao Dejie Du Long Song Lulu Tian Xiaoming Xie Zhaoyan Chen Yanpeng Ding Xuejiao Cheng Yingyin Yao Weilong Guo Zhenqi Su Qixin Sun Zhongfu Ni Lingling Chai Jie Liu 2023Journal of Genetics and Genomics2023,50,11:0
18A highly conserved amino acid in high molecular weight glutenin subunit 1Dy12 contributes to gluten functionality and processing quality in wheat显示文摘Bread wheat(Triticum aestivum L.)is one of the most commonly consumed staples worldwide,with widespread uses in foods such as breads,noodles,cakes,and cookies(Veraverbeke and Delcour,2002).The specific cooking properties of wheat products are mainly conferred by the gluten proteins contained in wheat grains(Delcour et al.,2012).High molecular weight glutenin subunits(HMW-GSs)are important constituents of wheat gluten proteins,largely determining gluten elasticity and processing quality(Branlard and Dardevet,1985;Payne et al.,1988).Changfeng Yang Qian Chen Mingming Xin Zhenqi Su Jinkun Du Weilong Guo Zhaorong Hu Jie Liu Huiru Peng Zhongfu Ni Qixin Sun Yingyin Yao 2023Journal of Genetics and Genomics2023,50,11:0
19TaANR1-TaMADS25 module regulates lignin biosynthesis and root development in wheat(Triticum aestivum L.)显示文摘Common wheat is a staple food for 35%of the global population,therefore increasing wheat yield in an ever-changing environment is essential for food security in the present day(Peng et al.,2011).Root system is responsible for water and nutrient acquisition,thus crucial for competitive fitness and crop yield in challenging environments(Karlova et al.,2021;Liu et al.,2022).Over the past decades,extensive research has focused on identifying genes accountable for root growth and development in plants(Rogers and Benfey,2015).However,only a limited number of genes have been cloned in wheat(Li et al.,2021).Weiya Xu Yongming Chen Bin Liu Qiuyuan Li Yilan Zhou Xuanshuang Li Weilong Guo Zhaorong Hu Zhenshan Liu Mingming Xin Yingyin Yao Mingshan You Huiru Peng Zhongfu Ni Jiewen Xing 2023Journal of Genetics and Genomics2023,50,11:0
20Improvement of synergistic effect photocatalytic/peroxymonosulfate activation for degradation of amoxicillin using carbon dots anchored on rod-like CoFe_(2)O_(4)显示文摘β-lactam antibiotics in aquatic environment have severely damaged ecological stability and caused a series of environmental pollution problems to be solved urgently.Herein,a novel composite photocatalyst prepared by loading carbon dots(CDs)onto rod-like CoFe_(2)O_(4)(CFO),which can effectively degrade amoxicillin(AMX)by photocata lytic/peroxy mono sulfate(PMS)activation under visible light irradiation.The degradation results exhibits that the optimal degradation efficiency with 97.5%within 80 min is achievd by the CDs-CFO-5 composite.Such enhanced activity is ascribed to the introduction of CDs that effectively improves the separation efficiency of photogenerated electron pairs and creates new active sites as electron bridges that improve the photocata lytic performance.More importantly,a strong synergistic between CDs and photo-induced electrons generated from CFO can further activiate PMS to provide more SO4-·and·OH radicals for boosting the degradation ability towards AMX.The present study aims to elucidate positive role of CDs in photocata lytic/peroxy monosulfate activation during the degradation reaction.Weilong Shi Yanan Liu Wei Sun Yuanzhi Hong Xiangyu Li Xue Lin Feng Guo Junyou Shi 2022Chinese Journal of Chemical Engineering2022,,12:0
