| 3 | Genome-wide association analysis reveals genetic loci and candidate genes associated with intramuscular fat in Duroc pigs显示文摘Intramuscular fat(IMF) is a major meat-quality trait in pigs. The content of IMF is directly associated with the taste and flavor of pork. As a complex trait, there could be multiple genes affecting IMF content in pork. Genomewide association study is a powerful tool to detect genomic regions associated with phenotypic variations. The objectives of the present study were to identify or refine the positions of genomic regions affecting IMF, and to characterize candidate genes and pathways that may influence this trait. Of note, we identified a significant region in longissium dorsi muscle in a Duroc pig population for IMF content with Porcine SNP60 v2 Bead Chip. This region spans 1.24 Mb on chromosome 8 and had been identified as a quantitative trait locus for IMF in Pietrain, Large White, Landrace, and Leicoma pigs. In this region, eight SNPs were significantly associated with IMF content. Three genes proximal to these significant SNPs were considered candidate genes, including ZDHHC16, LOC102162218 and PCDH7. Our results confirm several previous findings and highlight several genes that may contribute to IMF variation in Duroc pigs. | Xingwang WANG Rongrong DING Jianping QUAN Linxue YANG Ming YANG Enqin ZHENG Dewu LIU Gengyuan CAI Zhenfang WU Jie YANG | 2017 | Frontiers of Agricultural Science and Engineering2017，4，3： | 1 |
| 4 | Improving the accuracy of genomic prediction for meat quality traits using whole genome sequence data in pigs显示文摘Background Pork quality can directly affect customer purchase tendency and meat quality traits have become valu-able in modern pork production.However,genetic improvement has been slow due to high phenotyping costs.In this study,whole genome sequence(WGS)data was used to evaluate the prediction accuracy of genomic best linear unbiased prediction(GBLUP)for meat quality in large-scale crossbred commercial pigs.Results We produced WGS data(18,695,907 SNPs and 2,106,902 INDELs exceed quality control)from 1,469 sequenced Duroc×(Landrace×Yorkshire)pigs and developed a reference panel for meat quality including meat color score,marbling score,L*(lightness),a*(redness),and b*(yellowness)of genomic prediction.The prediction accuracy was defined as the Pearson correlation coefficient between adjusted phenotypes and genomic estimated breeding values in the validation population.Using different marker density panels derived from WGS data,accuracy differed substantially among meat quality traits,varied from 0.08 to 0.47.Results showed that MultiBLUP outperform GBLUP and yielded accuracy increases ranging from 17.39%to 75%.We optimized the marker density and found medium-and high-density marker panels are beneficial for the estimation of heritability for meat quality.Moreover,we conducted genotype imputation from 50K chip to WGS level in the same population and found average concord-ance rate to exceed 95%and r^(2)=0.81.Conclusions Overall,estimation of heritability for meat quality traits can benefit from the use of WGS data.This study showed the superiority of using WGS data to genetically improve pork quality in genomic prediction. | Zhanwei Zhuang Jie Wu Yibin Qiu Donglin Ruan Rongrong Ding Cineng Xu Shenping Zhou Yuling Zhang Yiyi Liu Fucai Ma Jifei Yang Ying Sun Enqin Zheng Ming Yang Gengyuan Cai Jie Yang Zhenfang Wu | 2023 | Journal of Animal Science and Biotechnology2023，14，5： | 1 |
| 5 | Network analysis of eight industrial symbiosis systems显示文摘工业共生是一个 eco 工业的公园的精华的特征。把公园划分成不同类型,主要集中于质的判断,并且没能使用度量标准在一个公园的内部结构或功能的特征上进行量的研究的以前的研究。分析一公园结构的属性,从网络分析的度量标准的一个范围被使用了,但是很少研究人员比较了二或用多重度量标准的更多的 symbioses。在这研究,我们使用了二个度量标准(密度和网络度集中化) 比较完全性的度和八个多样却代表性的工业共生网络的依赖。通过二个度量标准的联合,我们把网络划分了成三种类型:强壮的完全性的弱完全性,和二种形式,也就是抛锚承租人互助论和面向平等的互助论。结果证明有完全性的弱度的网络是稀少的并且在节点之中有很少连接;为锚承租人互助论,完全性的度相对高,但是 affiliated members 太依赖于核心成员;并且在有的面向平等的互助论的成员等于角色,与多样、灵活的共生路径。这些结果揭示了一些系统内部结构并且不同结构怎么在一个系统的成员之中影响了材料,精力,和知识的交换,从而提供卓见进可以使动摇的威胁网络。把分析基于这,我们在一个典型中国 eco 工业的公园(山东 Lubei ) 里提供优点的例子和最近的改进工程的有效性。 | Yan ZHANG Hongmei ZHENG Han SHI Xiangyi YU Gengyuan LIU Meirong SU Yating LI Yingying CHAI | 2016 | Frontiers of Earth Science2016，10，2： | 1 |

| 8 | Comparison of birth weight and umbilical and placental characteristics of cloned and arti?cial insemination-derived piglets显示文摘Somatic cell nuclear transfer(SCNT)-derived piglets have signi?cantly higher stillbirth rate and postnatal mortality rate than arti?cial insemination(AI)-generated piglets. The question whether the low survival rate of SCNT piglets was related to birth weight, umbilical cord or placenta development was investigated. In this study,stillbirth rate, neonatal death rate, birth weight, umbilical cord status, placental parameters and placental gene expression patterns were compared between SCNT and AI piglets. Results showed that mortality rates at birth and during the neonatal stage of SCNT piglets were signi?-cantly higher than those of AI piglets. The incidence of abnormal umbilical cord in SCNT and SCNT-liveborn(SCNT-LB) piglets was signi?cantly higher than in AI and AI-liveborn(AI-LB) piglets. Birth weight, placental weight, placental surface area and placental ef?ciency in SCNT and SCNT-LB piglets were signi?cantly lower than those of AI and AI-LB piglets. Placental expression pro?les of imprinting, angiopoiesis and nutrient transportrelated genes were defective in SCNT-LB piglets compared with those in AI-LB piglets. Thus, the low survival rate of SCNT piglets may be associated with abnormal umbilical cord and placenta development. These characteristics may have resulted from aberrant expression of angiogenesis, nutrient transport, and imprinting-related genes in the placentas. | Zheng AO Chengfa ZHAO Yanmin GAN Xiao WU Junsong SHI Enqin ZHENG Dewu LIU Gengyuan CAI Zhenfang WU Zicong LI | 2019 | Frontiers of Agricultural Science and Engineering2019，6，1： | 0 |
| 9 | Effects of enucleation method on in vitro and in vivo development rate of cloned pig embryos显示文摘Enucleation is a crucial procedure for mammalian somatic cell nuclear transfer(SCNT), especially for domestic animal cloning. Oocytes of domestic animals such as pigs and cattle contain dark lipid droplets that hinder localization and removal of the nucleus. Using an oocyte enucleation technique that can obtain a high enucleation rate but has minimal negative effects on the reprogramming potential of oocyte for cloning is bene?cial for enhancing the outcome of SCNT. In this study, we compared the pig cloning ef?ciency resulting from blind aspiration-based(BA-B) enucleation and spindle imaging system-assisted(SIS-A) enucleation, and compared the pig SCNT success rate associated with BA-B enucleation and blind aspiration plus post-enucleation staining-based(BAPPS-B) enucleation. SIS-A enucleation achieved a signi?cantly higher oocyte enucleation success rate and tended to obtain a higher in vivo full term development rate of SCNT embryos than BA-B enucleation. BAPPS-B enucleation also obtained signi?cantly higher in vitro as well as in vivo full term development ef?ciency of cloned porcine embryos than BA-B enucleation. These data indicate that SIS-A and BAPPS-B enucleation are better approaches for pig SCNT than BA-B enucleation. | Chengcheng ZHAO Junsong SHI Rong ZHOU Ranbiao MAI Lvhua LUO Xiaoyan HE Hongmei JI Gengyuan CAI Dewu LIU Enqin ZHENG Zhenfang WU Zicong LI | 2019 | Frontiers of Agricultural Science and Engineering2019，6，1： | 0 |

| 13 | Urban constructed wetlands: Assessing ecosystem services and disservices for safe, resilient, and sustainable cities显示文摘Climate change and rapid urbanization are pressing environmental and social concerns, with approximately 56% of the global population living in urban areas. This number is expected to rise to 68% by 2050, leading to the expansion of cities and encroachment upon natural areas, including wetlands, causing their degradation and fragmentation. To mitigate these challenges, green and blue infrastructures (GBIs), such as constructed wetlands, have been proposed to emulate and replace the functions of natural wetlands. This study evaluates the potential of eight constructed wetlands near Beijing, China, focusing on their ecosystem services (ESs), cost savings related to human health, growing/maintenance expenses, and disservices using an emergy-based assessment procedure. The results indicate that all constructed wetlands effectively purify wastewater, reducing nutrient concentrations (e.g., total nitrogen, total phosphorus, and total suspended solids). Among the studied wetlands, the integrated vertical subsurface flow constructed wetland (CW-4) demonstrates the highest wastewater purification capability (1.63E+14 sej/m^(2)/yr) compared to other types (6.78E+13 and 2.08E+13 sej/m^(2)/yr). Additionally, constructed wetlands contribute to flood mitigation, groundwater recharge, wildlife habitat protection, and carbon sequestration, resembling the functions of natural wetlands. However, the implementation of constructed wetlands in cities is not without challenges, including greenhouse gas emissions, green waste management, mosquito issues, and disturbances in the surrounding urban areas, negatively impacting residents. The ternary phase diagram reveals that all constructed wetlands provide more benefits than costs and impacts. CW-4 shows the highest benefit-cost ratio, reaching 50%, while free water surface constructed wetland (CW-3) exhibits the lowest benefits (approximately 38%), higher impacts (approximately 25%), and lower costs (approximately 37%) compared to other wetlands. The study advocates the use of an emergy approach as a reliable method to assess the quality of constructed wetlands, providing valuable insights for policymakers in selecting suitable constructed wetlands for effective urban ecological management. | Aamir Mehmood SHAH Gengyuan LIU Yu CHEN Qing YANG Ningyu YAN Feni AGOSTINHO Cecilia MVBALMEIDA Biagio FGIANNETTI | 2023 | Frontiers of Engineering Management2023，10，4： | 0 |
