| 1 | Genetic characterization and linkage disequilibrium mapping of resistance to gray leaf spot in maize(Zea mays L.)显示文摘Gray leaf spot(GLS),caused by Cercospora zeae-maydis,is an important foliar disease of maize(Zea mays L.)worldwide,resistance to which is controlled by multiple quantitative trait loci(QTL).To gain insights into the genetic architecture underlying the resistance to this disease,an association mapping population consisting of 161 inbred lines was evaluated for resistance to GLS in a plant pathology nursery at Shenyang in 2010 and 2011.Subsequently,a genome-wide association study,using 41,101 single-nucleotide polymorphisms(SNPs),identified 51 SNPs significantly(P<0.001)associated with GLS resistance,which could be converted into 31 QTL.In addition,three candidate genes related to plant defense were identified,including nucleotidebinding-site/leucine-rich repeat,receptor-like kinase genes similar to those involved in basal defense.Two genic SNPs,PZE-103142893 and PZE-109119001,associated with GLS resistance in chromosome bins 3.07 and 9.07,can be used for marker-assisted selection(MAS)of GLS resistance.These results provide an important resource for developing molecular markers closely linked with the target trait,enhancing breeding efficiency. | Liyu Shi Xiangling Lv Jianfeng Weng Hanyong Zhu Changlin Liu Zhuanfang Hao Yu Zhou Degui Zhang Mingshun Li Xiaoke Ci Xinhai Li Shihuang Zhang | 2014 | The Crop Journal2014，2，Z1： | 9 |

| 3 | The histone H3 lysine-27 demethylase Jmjd3 plays a critical role in specific regulation of Th17 cell differentiation显示文摘Interleukin(IL)17-producing T helper(Th17)cells play critical roles in the clearance of extracellular bacteria and fungi as well as the pathogenesis of various autoimmune diseases,such as multiple sclerosis,psoriasis,and ulcerative colitis.Although a global transcriptional regulatory network of Th17 cell differentiation has been mapped recently,the participation of epigenetic modifications in the differentiation process has yet to be elucidated.We demonstrated here that histone H3 lysine-27(H3K27)demethylation,predominantly mediated by the H3K27 demethylase Jmjd3,crucially regulated Th17 cell differentiation.Activation of naı¨ve CD41 T cells immediately induced high expression of Jmjd3.Genetic depletion of Jmjd3 in CD41 T cells specifically impaired Th17 cell differentiation both in vitro and in vivo.Ectopic expression of Jmjd3 largely rescued the impaired differentiation of Th17 cells in vitro in Jmjd3-deficientCD41 T cells.Importantly,Jmjd3-deficient mice were resistant to the induction of experimental autoimmune encephalomyelitis(EAE).Furthermore,inhibition of the H3K27 demethylase activity with the specific inhibitor GSK-J4 dramatically suppressed Th17 cell differentiation in vitro.At the molecular level,Jmjd3 directly bound to and reduced the level of H3K27 trimethylation(me3)at the genomic sites ofRorc,which encodes the masterTh17 transcription factorRorgt,and Th17 cytokine genes such as Il17,Il17f,and Il22.Therefore,our studies established acritical role of Jmjd3-mediatedH3K27demethylation inTh17 cell differentiation andsuggest that Jmjd3 can be a novel therapeutic target for suppressing autoimmune responses. | Zhi Liu Wei Cao Longxia Xu Xi Chen Yu Zhan Qian Yang Sanhong Liu Pengfei Chen Yuhang Jiang Xiaohua Sun Yu Tao Yiming Hu Cuifeng Li Qi Wang Ying Wang Charlie Degui Chen Yufang Shi Xiaoren Zhang | 2015 | Journal of Molecular Cell Biology2015，7，6： | 6 |
| 4 | Identification of Functional Genetic Variations Underlying Drought Tolerance in Maize Using SNP Markers显示文摘Single nucleotide polymorphism (SNP) is a common form of genetic variation and popularly exists in maize genome. An Illumina GoldenGate assay with 1 536 SNP markers was used to genotype maize inbred lines and identified the functional genetic variations underlying drought tolerance by association analysis. Across 80 lines, 1 006 polymorphic SNPs (65.5% of the total) in the assay with good call quality were used to estimate the pattern of genetic diversity, population structure, and familial relatedness. The analysis showed the best number of fixed subgroups was six, which was consistent with their original sources and results using only simple sequence repeat markers. Pairwise linkage disequilibrium (LD) and association mapping with phenotypic traits investigated under water-stressed and well-watered regimes showed rapid LD decline within 100-500 kb along the physical distance of each chromosome, and that 29 SNPs were associated with at least two phenotypic traits in one or more environments, which were related to drought-tolerant or drought-responsive genes. These drought-tolerant SNPs could be converted into functional markers and then used for maize improvement by marker-assisted selection. | Zhuanfang Hao Xinhai Li Chuanxiao Xie Jianfeng Weng Mingshun Li Degui Zhang Xiaoling Liang Lingling Liu Sisi Liu Shihuang Zhang | 2011 | Journal of Integrative Plant Biology2011，53，8： | 5 |
| 5 | PhieCBEs:Plant High-Efficiency Cytidine Base Editors with Expanded Target Range显示文摘Clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)-mediated genome editing can efficiently produce gene-knockout mutants.On the other hand,CRISPR/Cas-derived base editors offer the ability to induce precise nucleotide substitutions(Komor et al.,2016).Cytidine base editors(CBEs)consist of a cytidine deaminase fused with a Cas9-nickase variant(Cas9n,with a D10A substitu-tion)and can achieve site-specific C-to-T substitution.Similarly,adenine base editors use an adenine deaminase forA-to-G substi-tution.These systems have been used in various organisms(Mishra et al.,2019).However,the Cas9 complex requires target sites containing NGG protospacer adjacent motifs(PAMs),thus restricting selection of potential targets.A number of CBEs have been developed using Cas9 variants(mostly Cas9n),cytidine deaminases(such as rAPOBEC1 and PmCDA1),and uracil glycosylase inhibitor(UGI)domains.These CBEs of the first generation(BE1,rAPOBEC1-dCas9),second generation(BE2,rAPOBEC1-dCas9-UGI),and third generation(BE3,rAPOBEC1-Cas9n-UGI)have moderate editing efficiencies in mammalians(Komor etal.,2016). | Dongchang Zeng Taoli Liu Jiantao Tan Yaling Zhang Zhiye Zheng Bin Wang Degui Zhou Xianrong Xie Menghui Guo Yao-Guang Liu Qinlong Zhu | 2020 | Molecular Plant2020，13，12： | 5 |

| 9 | Highly sensitive fluorescence detection of chloride ion in aqueous solution with Ag-modified porous g-C_(3)N_(4) nanosheets显示文摘The porous g-C_(3)N_(4)(PCN)nanosheets are successfully synthesized and further modified with nano-sized Ag by a simple wet-chemical process.Intere stingly,the Ag-modified porous g-C_(3)N_(4)(Ag-PCN)nanosheets exhibit competitive fluorescence detection performance of chloride ion(Cl)in aqueous solutio n.Under the optimized conditions,the concentration of Cl could be quantitative analyzed with the Ag-PCN in a wide detection range from 0.5 mmol/L to 0.1 mol/L,with a low detection limitation of 0.06 mmol/L.It is confirmed that the fluorescence of PCN could be effectively decayed by the photoinduced charge transfer via the adsorbed Cl for trapping holes,mainly by means of the time-resolved fluorescence and surface photo voltage spectra.The porous structure and modified Ag promote the adsorption of Cl on resulting Ag-PCN,leading to excellent fluorescence detection for Cl.This work provides a feasible route to develop a fluorescence detection of Cl with g-C_(3)N_(4) nanosheets in environment water. | Zishu Zhang Ying Gao Peng Li Binhong Qu Zhiyuan Mu Yang Liu Yang Qu Degui Kong Qing Chang Liqiang Jing | 2020 | Chinese Chemical Letters2020，31，10： | 2 |
| 10 | Knockout of glutathione peroxidase 5 down-regulates the piRNAs in the caput epididymidis of aged mice显示文摘The mammalian epididymis not only plays a fun dame ntal role in the maturati on of spermatozoa,but also provides protecti on agai nst various stressors.The foremost among these is the threat posed by oxidative stress,which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids,proteins,and nucleic acids.In mice,the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5(GPX5)as a major luminal scavenger in the proximal caput epididymidal segment.Accordingly,the loss of GPX5^-/-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx57 mice.To explore the underlying mechanism,we have conducted transcriptomic analysis of caput epididymidal epithelial cells from aged(13 months old)Gpx5^-/-m mice.This analysis revealed the dysregulation of several thousand epididymal mRNA transcripts,in eluding the downregulation of a subgroup of piRNA pathway gen es,in aged Gpx5^-/-mice.In agreeme nt with these fin dings,we also observed the loss of piRNAs,which potentially bind to the P-element-induced wimpy testis(PlWI)-like proteins PIWIL1 and PIWIL2.The absence of these piRNAs was correlated with the elevated mRNA levels of their putative gene targets in the caput epididymidis of Gpx5^-/-mice.Importantly,the oxidative stress response genes tend to have more targeting piRNAs,and many of them were among the top increased genes upon the loss of GPX5^-/-.Taken together,our findings suggest the existence of a previously uncharacterized somatic piRNA pathway in the mammalian epididymis and its possible invoIvement in the aging and oxidative stress-mediated responses. | Chen Chu Lu Yu Joelle Henry-Berger Yan-Fei Ru Ayhan Kocer Alexandre Champroux Zhi-Tong Li Miao He Sheng-Song Xie Wu-Bin Ma Min-Jie Ni Zi-Mei Ni Yun-Li Guo Zhao-Liang Fei Lan-Tao Gou Qiang Liu Samanta Sharma Yu Zhou Mo-Fang Liu Charlie Degui Chen Andrew L Eamens Brett Nixon Yu-Chuan Zhou Joel R Drevet Yong-Lian Zhang | 2020 | Asian Journal of Andrology2020，22，6： | 2 |
