| 2 | Status monitoring and health assessment of Luhuitou fringing reef of Sanya, Hainan, China显示文摘The monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. The mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem. | ZHANG Qiaomin SHI Qi CHEN Gang FONG T C W WONG D C C HUANG Hui WANG Hankui ZHAO Meixia | 2006 | Chinese Science Bulletin2006，51，B12： | 15 |

| 4 | Estimate of carbonate production by scleractinian corals at Luhuitou fringing reef,Sanya,China显示文摘Carbonate production by scleractinian corals not only maintains coral reef growth, but also represents an important source of atmospheric carbon dioxide. In this paper the carbonate production by scler-actinian corals at Luhuitou fringing reef, Sanya, Hainan Island, China, is investigated with an ecological census-based method. Averaged carbonate production is 1.16 ± 0.55 kg·m-2·a-1 and 3.52 ± 1.32 kg·m-2·a-1 on the reef flat and reef slope, respectively, depending on the composition and distribution of corals and the intergeneric difference of skeletal growth. In response to the rapidly increasing human impacts, coral carbonate production has decreased by 80%―89% at this fringing reef since the 1960s; as a result, the reef accretion rate declined and became lower than the rate of sea level rise. Further development of the Luhuitou fringing reef will switch significantly from lateral extension sea-wards to vertical growth, reflecting a response of coral reef biogeomorphic process to strong human impacts under the background of global sea level rise. In addition, decrease in coral carbonate production reduced CO2 release from this fringing reef. In the future, it is likely that the role played by coral reefs, especially of fringing reefs, in the ocean and even in the global carbon cycle will be modified or weakened by the increasing human impacts. | SHI Qi ZHAO MeiXia ZHANG QiaoMin YU KeFu CHEN TianRan LI Shu WANG HanKui | 2009 | Chinese Science Bulletin2009，54，4： | 7 |

| 8 | Co-evolution of plant LTR-retrotransposons and their host genomes显示文摘Transposable elements(TEs),particularly,long terminal repeat retrotransposons(LTR-RTs),are the most abun-dant DNA components in all plant species that have been investigated,and are largely responsible for plant genome size variation.Although plant genomes have experi-enced periodic proliferation and/or recent burst of LTR-retrotransposons,the majority of LTR-RTs are inactivated by DNA methylation and small RNA-mediated silencing mechanisms,and/or were deleted/truncated by unequal homologous recombination and illegitimate recombina-tion,as suppression mechanisms that counteract genome expansion caused by LTR-RT amplifi cation.LTR-RT DNA is generally enriched in pericentromeric regions of the host genomes,which appears to be the outcomes of pref-erential insertions of LTR-RTs in these regions and low effectiveness of selection that purges LTR-RT DNA from these regions relative to chromosomal arms.Potential functions of various TEs in their host genomes remain blurry;nevertheless,LTR-RTs have been recognized to play important roles in maintaining chromatin structures and centromere functions and regulation of gene expres-sions in their host genomes. | Meixia Zhao Jianxin Ma | 2013 | Protein & Cell2013，4，7： | 4 |

| 10 | Overexpression of IbSINA5 Increases Cold Tolerance through a CBF SINA-COR Mediated Module in Sweet Potato显示文摘Seven in absentia(SINA)family proteins play a central role in plant growth,development and resistance to abiotic stress.However,their biological function in plant response to cold stress is still largely unknown.In this work,a seven in absentia gene IbSINA5 was isolated from sweet potato.Quantitative real-time polymerase chain reaction(qRT-PCR)analyses demonstrated that IbSINA5 was ubiquitously expressed in various tissues and organs of sweet potato,with a predominant expression in fibrous roots,and was remarkably induced by cold,drought and salt stresses.Subcellular localization assays revealed that IbSINA5-GFP fusion protein was mainly localized in cytoplasm and nucleus.Overexpression of IbSINA5 in sweet potato led to dramatically improved resistance to cold stress in transgenic plants,which was associated with the up-regulated expression of IbCOR(cold-regulated)genes,increased proline production,and decreased malondialdehyde(MDA)and H2O2 accumulation in the leaves of transgenic plants.Furthermore,transient expression of IbCBF3,a C-repeat binding factor(CBF)gene,in the leaf protoplasts of wild type sweet potato plants up-regulated the expression of both IbSINA5 and IbCOR genes.Our results suggest that IbSINA5 could function as a positive regulator in the cold signaling pathway through a CBF-SINA-COR mediated module in sweet potato,and have a great potential to be used as a candidate gene for the future breeding of new plant species with improved cold resistance. | Shiyang Li Xue-Ao Liu Lizi Zhao Huiqing Huang Bei Li Zhizhong Song Meixia Liang Hongxia Zhang Limin Wang Shenglin Zhou | 2021 | Phyton-International Journal of Experimental Botany2021，90，3： | 1 |
| 11 | Significant variations in alternative splicing patterns and expression profiles between human-mouse orthologs in early embryos显示文摘Human and mouse orthologs are expected to have similar biological functions; however, many discrepancies have also been reported. We systematically compared human and mouse orthologs in terms of alternative splicing patterns and expression profiles. Human-mouse orthologs are divergent in alternative splicing, as human orthologs could generally encode more isoforms than their mouse orthologs. In early embryos, exon skipping is far more common with human orthologs, whereas constitutive exons are more prevalent with mouse orthologs. This may correlate with divergence in expression of splicing regulators. Orthologous expression similarities are different in distinct embryonic stages, with the highest in morula. Expression differences for orthologous transcription factor genes could play an important role in orthologous expression discordance. We further detected largely orthologous divergence in differential expression between distinct embryonic stages. Collectively, our study uncovers significant orthologous divergence from multiple aspects, which may result in functional differences and dynamics between human-mouse orthologs during embryonic development. | Geng Chen Jiwei Chen Jianmin Yang Long Chen Xiongfei Qu Caiping Shi Baitang Ning Leming Shi Weida Tong Yongxiang Zhao Meixia Zhang Tieliu Shi | 2017 | Science China(Life Sciences)2017，60，2： | 1 |
| 12 | Modulation of ionic arrangement in polar magnet by chemical pressure显示文摘The similarity of local structure-connection pattern and volumetrically compressive strain between host and guest phases can be used to stabilize heteroid metastable matter and tune the local structure and properties.Here a series of metastable ABO_(3)(A=Mn;B=Mn_(0.5)Mo_(0.5),Mn_(1/3)Ta_(2/3),and Mn_(0.5)Ta_(0.5)) were trapped in LiTaO_(3) to form solid-solutions,where the difference of solid solubility limit reveals the barrier of size effect on chemical pressure.All samples show antiferromagnetic characters,in which the(LiTaO_(3))_(1-x)-[Mn(Mn_(0.5)Mo_(0.5))O_(3)]_(x) series exhibit more complex magnetic and dielectric behaviors with the increasing of metastable guest phase,stemming from the complex interactive mechanism between Mn^(2+)and Mo^(6+).The cell parameter variation of (LiTaO_(3))_(1-z)-[Mn(Mn_(0.5)Ta_(0.5))O_(3)]_zshows a more regularly changing tendency,on account of the smallest size barrier.These findings show that chemical pressure can effectively stimulate the physical pressure to intercept and modulate a metastable phase at atomic-scale by compressibility effect between like structures at ambient pressure. | Shuang Zhao Jinjin Yang Yifeng Han Meixia Wu Man-Rong Li | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
| 13 | A reference-grade genome assembly for Astragalus mongholicus and insights into the biosynthesis and high accumulation of triterpenoids and flavonoids in its roots显示文摘Astragalus membranaceus var.mongholicus(AMM),a member of the Leguminosae,is one of the most important medicinal plants worldwide.The dried roots of AMM have a wide range of pharmacological effects and are a traditional Chinese medicine.Here,we report the first chromosome-level reference genome of AMM,comprising nine pseudochromosomes with a total size of 1.47 Gb and 27868 protein-encoding genes.Comparative genomic analysis reveals that AMM has not experienced an independent wholegenome duplication(WGD)event after the WGD event shared by the Papilionoideae species.Analysis of long terminal repeat retrotransposons suggests a recent burst of these elements at approximately 0.13 million years ago,which may explain the large size of the AMM genome.Multiple gene families involved in the biosynthesis of triterpenoids and flavonoids were expanded,and our data indicate that tandemduplication has been the main driver for expansion of these families.Among the expanded families,the phenylalanine ammonia-lyase gene family was primarily expressed in the roots of AMM,suggesting their roles in the biosynthesis of phenylpropanoid compounds.The functional versatility of 2,3-oxidosqualene cyclase genes in cluster Ⅲ may play a critical role in the diversification of triterpenoids in AMM.Our findings provide novel insights into triterpenoid and flavonoid biosynthesis and can facilitate future research on the genetics and medical applications of AMM. | Yi Chen Ting Fang He Su Sifei Duan Ruirui Ma Ping Wang Lin Wu Wenbin Sun Qichen Hu Meixia Zhao Lianjun Sun Xuehui Dong | 2023 | Plant Communications2023，4，2： | 0 |
| 14 | Recognition for avian influenza virus proteins based on support vector machine and linear discriminant analysis显示文摘Total 200 properties related to structural characteristics were employed to represent structures of 400 HA coded proteins of influenza virus as training samples. Some recognition models for HA proteins of avian influenza virus (AIV) were developed using support vector machine (SVM) and linear discriminant analysis (LDA). The results obtained from LDA are as follows: the identification accuracy (Ria) for training samples is 99.8% and Ria by leave one out cross validation is 99.5%. Both Ria of 99.8% for training samples and Ria of 99.3% by leave one out cross validation are obtained using SVM model, respectively. External 200 HA proteins of influenza virus were used to validate the external predictive power of the resulting model. The external Ria for them is 95.5% by LDA and 96.5% by SVM, respectively, which shows that HA proteins of AIVs are preferably recognized by SVM and LDA, and the performances by SVM are superior to those by LDA. | LIANG GuiZhao CHEN ZeCong YANG ShanBin MEI Hu ZHOU Yuan YANG Li ZHOU Peng YANG ShengXi SHU Mao LIAO ChunYang WU ShiRong LI GenRong HE Liu GAO JianKun Gan MengYu LI DeJing CHEN GuoPing WANG GuiXue LONG Sha JING JuHua ZHENG XiaoLin ZENG Hui ZHANG QiaoXia ZHANG MengJun YANG Qi TIAN FeiFei TONG JianBo WANG JiaoNa LIU YongHong LI Bo QIU LiangJia CAI ShaoXi ZHAO Na YANG Yan SU XiaLi SONG Jian CHEN MeiXia ZHANG XueJiao SUN JiaYing LI JingWei CHEN GuoHua CHEN Gang DENG Jie PENG ChuanYou ZHU WanPing XU LuoNan WU YuQuan LIAO LiMin LI Zhi LI Jun LU DaJun SU QinLiang HUANG ZhengHu ZHOU Ping LI ZhiLiang | 2008 | Science China Chemistry2008，51，2： | 0 |
| 15 | Mutation spectrum in GNAQ and GNA11 in Chinese uveal melanoma显示文摘Uveal melanoma is the most common intraocular cancer in the adult eye.R183 and Q209 were found to be mutational hotspots in exon 4 and exon 5 of GNAQ and GNA11 in Caucasians.However,only a few studies have reported somaticmutations in GNAQ or GNA11 in uveal melanoma in Chinese.We extracted somatic DNA from paraffin-embedded biopsies of 63 Chinese uveal melanoma samples and sequenced the entire coding regions of exons 4 and 5 in GNAQ and GNA11.The results showed that 33%of Chinese uveal melanoma samples carried Q209 mutations while none had R183 mutation in GNAQ or GNA11.In addition,seven novel missense somatic mutations in GNAQ(Y192C,F194L,P170S,D236N,L232F,V230A,and M227I)and four novel missense somatic mutations in GNA11(R166C,I200T,S225F,and V206M)were found in our study.The high mutation frequency of Q209 and the novel missense mutations detected in this study suggest that GNAQ and GNA11 are common targets for somatic mutations in Chinese uveal melanoma. | Edward D.Zhang Meixia Zhang Gen Li Charlotte L.Zhang Zhihuan Li Guangxi Zang Zhiguang Su Ming Zhang Daoman Xiang Ling Zhao Jie Zhu | 2019 | Precision Clinical Medicine2019，2，4： | 0 |
| 16 | Sister-city Ties and Chinese Outward Foreign Direct Investment:A Spatial Econometric Analysis显示文摘This paper employs dynamic spatial econometric methods to analyze the impact of the sister-city relationship on Chinese outward foreign direct investment(OFDI)using a linked country-level dataset from 2003 to 2016.The results show strong and robust evidence that the sister-city relationship has been a crucial OFDI location determinant in host countries and their neighbors.Specifically,the sister-city tie between China and the host country has stimulated Chinese OFDI in host countries.Moreover,Chinese OFDI in host countries would be reduced if China concluded sister-city ties with their neighbors to which we refer as the neighboring effect.Further mechanism tests show that sister cities have promoted OFDI in host countries via four channels:reducing political risk,decreasing information asymmetry,narrowing institutional distance,and mitigating cultural differences.This tendency for sister-city links to promote OFDI has varied substantially depending on OFDI entry modes(i.e.,greenfield or cross-border mergers and acquisitions),motivation(i.e.,resource-,market-,technology-,or efficiency-oriented OFDI),and Sino–foreign geographical relationships(i.e.,Belt and Road Initiative countries or other countries). | Youxing Huang Meixia Dong Yanping Zhao | 2024 | China & World Economy2024，32，1： | 0 |
| 17 | Effects of herbicide butachlor application on the growth of periphytic biofilms and nitrogen loss in paddy systems显示文摘The application of butachlor as an herbicide in paddy fields is widely practiced,aiming to increase rice yield by directly or indirectly influencing the paddy environment.Periphytic biofilms,which form at the soil-water interface in paddy fields,are complex bioaggregates that play an important role in nitrogen (N) cycling.The objective of this study was to investigate the effect of butachlor on periphytic biofilm growth and N cycling under both light and dark conditions in the laboratory.The results revealed that butachlor application hindered the growth of periphytic biofilms and led to the dominance of Cyanobacteria as the primary prokaryotes,while inhibiting the development of eukaryotic Trebouxiophyceae.Furthermore,the application of butachlor reduced the richness and diversity of prokaryotes,but increased those of eukaryotes in periphytic biofilms.The light treatments exhibited higher total N loss because light favored periphytic biofilm growth and enhanced ammonium (NH_(4)^(+)) assimilation and nitrification.Additionally,butachlor application resulted in the increased retention of NH_(4)^(+)-N and nitrate (NO_(3)^(-))-N and an increase in N loss via denitrification.The abundances of functional genes encoding enzymes such as ammonia monooxygenase,nitrite reductase,and nitrous oxide reductase were increased by butachlor application,favoring nitrification and denitrification processes.Overall,the results suggest that butachlor application leads to an increase in total N loss mainly through denitrification in paddy systems,particularly in the presence of periphytic biofilms.Thus,the results may provide valuable insights into the changes in periphytic biofilm growth and N cycling induced by butachlor,and future studies can further explore the potential implications of these changes in paddy soils. | Yanhui ZHAO Mingjun LEI Liandong JING Fan XIA Meixia YAN Jiantong LIU Yonghong WU Yunli WU Chenxi WU | 2024 | Pedosphere2024，34，1： | 0 |
