| 1 | Size distribution and source of heavy metals in particulate matter on the lead and zinc smelting affected area显示文摘In order to understand the size distribution and the main kind of heavy metals in particulate matter on the lead and zinc smelting affected area, particulate matter(PM) and the source samples were collected in Zhuzhou, Hunan Province from December 2011 to January 2012 and the results were discussed and interpreted. Atmospheric particles were collected with different sizes by a cascade impactor. The concentrations of heavy metals in atmospheric particles of different sizes, collected from the air and from factories, were measured using an inductively coupled plasma mass spectrometry(ICP-MS). The results indicated that the average concentration of PM, chromium(Cr), arsenic(As), cadmium(Cd) and lead(Pb) in PM was177.3 ± 33.2 μg/m^3, 37.3 ± 8.8 ng/m^3, 17.3 ± 8.1 ng/m^3, 4.8 ± 3.1 ng/m^3 and 141.6 ± 49.1 ng/m^3,respectively. The size distribution of PM displayed a bimodal distribution; the maximum PM size distribution was at 1.1–2.1 μm, followed by 9–10 μm. The size distribution of As, Cd and Pb in PM was similar to the distribution of the PM mass, with peaks observed at the range of1.1–2.1 μm and 9–10 μm ranges while for Cr, only a single-mode at 4.7–5.8 μm was observed. PM(64.7%), As(72.5%), Cd(72.2%) and Pb(75.8%) were associated with the fine mode below 2.1 μm,respectively, while Cr(46.6%) was associated with the coarse mode. The size distribution characteristics, enrichment factor, correlation coefficient values, source information and the analysis of source samples showed that As, Cd and Pb in PM were the typical heavy metal in lead and zinc smelting affected areas, which originated mainly from lead and zinc smelting sources. | Kai Zhang Fahe Chai Zilong Zheng Qing Yang Xuecai Zhong Khanneh Wadinga Fomba Guangzhu Zhou | 2018 | Journal of Environmental Sciences2018，30，9： | 10 |
| 2 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |
| 3 | Using genomic data to improve the estimation of general combining ability based on sparse partial diallel cross designs in maize显示文摘Evaluation of general combining ability(GCA)is crucial to hybrid breeding in maize.Although the complete diallel cross design can provide an efficient estimation,sparse partial diallel cross(SPDC)is more flexible in breeding practice.Using real and simulated data sets of partial diallel crosses between 266 maize inbred lines,this study investigated the performance of SPDC designs for estimating the GCA.With different distributions of parental lines involved in crossing(called random,balanced and unbalanced samplings),different numbers of hybrids were sampled as the training sets to estimate the GCA of the 266 inbred lines.In this process,three statistical approaches were applied.One obtained estimations through the ordinary least square(OLS)method,and the other two utilized genomic prediction(GP)to estimate the GCA.It was found that the coefficient of determination of each approach was always higher than the heritability of a target trait,showing that the GCA for maize inbred lines could be accurately predicted with SPDC designs.Both the GP approaches were more accurate than the OLS,particularly in the scenario for a low-heritability trait with a small sample size.Additionally,prediction results demonstrated that a big sample of hybrids could greatly help improve the accuracy.The random sampling of parental lines had little influence on the average accuracy.However,the prediction for lines that never or seldom involved in crossing might suffer from much lower accuracy. | Xin Wang Zhenliang Zhang Yang Xu Pengchen Li Xuecai Zhang Chenwu Xu | 2020 | The Crop Journal2020，8，5： | 4 |
| 4 | A Teosinte-derived Allele of a MYB Transcription Repressor Confers Multiple Disease Resistance in Maize.显示文摘Natural alleles controlling multiple disease resistances (MDR) are valuable for crop breeding. However, only one MDR gene have been cloned in maize, and molecular mechanisms of MDR are not clear. By map-based cloning, we have cloned a teosinte-derived allele of a resistance gene, Mexicana lesion mimic 1 (ZmMM1), which has a lesion mimic phenotype and confers resistance to northern leaf blight (NLB), gray leaf spot (GLS) and southern corn rust (SCR). Strong MDR conferred by the teosinte allele is linked with the polymorphisms in the 3' untranslated region of the ZmMM1 gene that cause increased accumulation of ZmMM1 protein. ZmMM1 acts as a transcription repressor and negatively regulates transcription of specific target genes including ZmMM1-target gene 3 (ZmMT3), which functions as a negative regulator of plant immunity and associated cell death. The successful isolation of the ZmMM1 resistance gene will help not only in developing broad-spectrum and durable disease resistance but also in understanding the molecular mechanisms underlying MDR. | Hongze Wang Jiabao Hou Pei Ye Long Hu Junshi Huang Zhikang Dai Bao Zhang Sha Dai Jiamin Que Haoxuan Min Gengshen Chen Yanbo Wang Min Jiang Yan Liang Lin Li Xuecai Zhang Zhibing Lai | 2021 | Molecular Plant2021，14，11： | 4 |
| 5 | Genome-wide association study and genomic prediction of Fusarium ear rot resistance in tropical maize germplasm显示文摘Fusarium ear rot(FER)is a destructive maize fungal disease worldwide.In this study,three tropical maize populations consisting of 874 inbred lines were used to perform genomewide association study(GWAS)and genomic prediction(GP)analyses of FER resistance.Broad phenotypic variation and high heritability for FER were observed,although it was highly influenced by large genotype-by-environment interactions.In the 874 inbred lines,GWAS with general linear model(GLM)identified 3034 single-nucleotide polymorphisms(SNPs)significantly associated with FER resistance at the P-value threshold of 1×10^(-5),the average phenotypic variation explained(PVE)by these associations was 3%with a range from 2.33%to 6.92%,and 49 of these associations had PVE values greater than 5%.The GWAS analysis with mixed linear model(MLM)identified 19 significantly associated SNPs at the P-value threshold of 1×10^(-4),the average PVE of these associations was 1.60%with a range from 1.39%to 2.04%.Within each of the three populations,the number of significantly associated SNPs identified by GLM and MLM ranged from 25 to 41,and from 5 to 22,respectively.Overlapping SNP associations across populations were rare.A few stable genomic regions conferring FER resistance were identified,which located in bins 3.04/05,7.02/04,9.00/01,9.04,9.06/07,and 10.03/04.The genomic regions in bins 9.00/01 and 9.04 are new.GP produced moderate accuracies with genome-wide markers,and relatively high accuracies with SNP associations detected from GWAS.Moderate prediction accuracies were observed when the training and validation sets were closely related.These results implied that FER resistance in maize is controlled by minor QTL with small effects,and highly influenced by the genetic background of the populations studied.Genomic selection(GS)by incorporating SNP associations detected from GWAS is a promising tool for improving FER resistance in maize. | Yubo Liu Guanghui Hu Ao Zhang Alexander Loladze Yingxiong Hu Hui Wang Jingtao Qu Xuecai Zhang Michael Olsen Felix San Vicente Jose Crossa Feng Lin Boddupalli M.Prasanna | 2021 | The Crop Journal2021，9，2： | 3 |
| 6 | The mutation network for the hemagglutinin gene from the novel influenza A (H1N1) virus显示文摘A mutation network for the hemagglutinin gene(HA) of the novel type A(H1N1) influenza virus was constructed.Sequence homology analysis indicated that one HA sequence type from the viruses mainly isolated from Mexico was likely the original type in this epidemic.Based on the 658A and 1408T mutations in HA,the viruses evolving into this epidemic were divided into three categories,the Mexico,the transitional and the New York type.The three groups of viruses presented distinctive clustering features in their geographic distributions. | HE YunGang DING GuoHui BIAN Chao HUANG Zhong LAN Ke SUN Bing WANG XueCai LI YiXue WANG HongYan WANG XiaoNing YANG Zhong ZHONG Yang JIN WeiRong XIONG Hui DAI JianXin GUO YaJun WANG Hao CHE XiaoYan WU Fan YUAN ZhenAn ZHANG Xi CAO ZhiWei ZHOU XiaoNong ZHOU JiaHai MA ZhiYong TONG GuangZhi ZHAO GuoPing JIN Li | 2009 | Chinese Science Bulletin2009，54，13： | 3 |
| 7 | Genomic prediction of the performance of hybrids and the combining abilities for line by tester trials in maize显示文摘The two most important activities in maize breeding are the development of inbred lines with high values of general combining ability(GCA)and specific combining ability(SCA),and the identification of hybrids with high yield potentials.Genomic selection(GS)is a promising genomic tool to perform selection on the untested breeding material based on the genomic estimated breeding values estimated from the genomic prediction(GP).In this study,GP analyses were carried out to estimate the performance of hybrids,GCA,and SCA for grain yield(GY)in three maize line-by-tester trials,where all the material was phenotyped in 10 to 11 multiple-location trials and genotyped with a mid-density molecular marker platform.Results showed that the prediction abilities for the performance of hybrids ranged from 0.59 to0.81 across all trials in the model including the additive effect of lines and testers.In the model including both additive and non-additive effects,the prediction abilities for the performance of hybrids were improved and ranged from 0.64 to 0.86 across all trials.The prediction abilities of the GCA for GY were low,ranging between-0.14 and 0.13 across all trials in the model including only inbred lines;the prediction abilities of the GCA for GY were improved and ranged from 0.49 to 0.55 across all trials in the model including both inbred lines and testers,while the prediction abilities of the SCA for GY were negative across all trials.The prediction abilities for GY between testers varied from-0.66 to 0.82;the performance of hybrids between testers is difficult to predict.GS offers the opportunity to predict the performance of new hybrids and the GCA of new inbred lines based on the molecular marker information,the total breeding cost could be reduced dramatically by phenotyping fewer multiple-location trials. | Ao Zhang Paulino Pérez-Rodríguez Felix San Vicente Natalia Palacios-Rojas Thanda Dhliwayo Yubo Liu Zhenhai Cui Yuan Guan Hui Wang Hongjian Zheng Michael Olsen Boddupalli M.Prasanna Yanye Ruan Jose Crossa Xuecai Zhang | 2022 | The Crop Journal2022，10，1： | 3 |

| 14 | Paleosalinity and lake level fluctuations of the 3rd Member of Paleogene Shahejie Formation,Chezhen Sag,Bohai Bay Basin显示文摘The Chezhen Sag,located in the north-western Jiyang Depression,is one of the most important oil-bearing sags in the Bohai Bay Basin.Due to the low degree of exploration in the sag,paleosalinity and sedimentary environment of the sag in the 3rd Member of Paleogene Shahejie Formation(Es3)is not clear.Recovering the paleosalinity and lake level fluctuations is helpful for understanding organic matter rich rocks sedimentation.Therefore,a detailed geochemical,mineralogical and paleontological analysis of the Es3 in the Chezhen Sag was conducted.Index like Sr/Ba ratios,B/Ga ratios,equivalent boron content and methods concluding Adams'formula and Couch's method were adopted to reveal the paleo-salinity and lake level variations.The results indicate that the lower submember(Lower Es3)was deposited in a salt water with high salinity,accompanied by dry climate and transgression event.The middle submember(Middle Es3)and upper submember(Upper Es3)record a freshwater to brackish environment.The paleosalinity and paleoclimate changes are consistent with the global sea level variations.The type and content of sporopollen indicate a dry climate in Lower Es3,which further confirms the reliability of the reconstruction results of paleosalinity.Combined with the paleoclimate and previous marine paleontological evidence,we proposed that the high salinity period is associated with a high lake level and a large-scale transgression event in Lower Es3.According to salinities and corresponding Lake depths,we established a sedimentary environment variation model of the Es3 Member in Chezhen Sag. | Long SUN Jinliang ZHANG Yang LI Xue YAN Xuecai ZHANG | 2022 | Frontiers of Earth Science2022，16，4： | 1 |

| 17 | Hypocotyl elongation based on HY5 transcription factor in cold resistant winter rapeseed(Brassica napus L.)显示文摘Winter rape(Brassica napus L.)is better than other edible oil crops in China,but poor cold resistance is the key factor restricting its development.Hypocotyl length was found closely related to cold tolerance.The correlation between hypocotyl length and semi-lethal low temperature was significant,and the highest correlation between hypocotyl length and LT50 of autumn sowing was 0.9557.When the hypocotyl were treated at low temperature,the cells were seriously damaged and formed cavity structures,with cell walls seriously damaged or merged into each other.The positive regulation gene of hypocotyl length in resistant line of VHTSG 10 was identified as HY5(transcription factor HY5-like)by qPCR,and bZIP transcription factor was found to be its conserved domain.Fused gene by GFP and HY5 from VHTSG 10 was transient transferred into Nicotiana benthamiana cells.Corresponding to the 35S:GFP widely distributed in plasma membrane of leaf epidermis,the fusion protein 35S:HY5-GFP was mainly distributed in nucleus.Thus we regarded BnHY5 gene is a key gene related to cold tolerance and hypocotyl length in B.napus. | Jiaojiao Jin Wancang Sun Junyan Wu Yan Fang Xuecai Li Li Ma Lijun Liu Rui Zeng | 2022 | Oil Crop Science2022，7，1： | 1 |
