| 1 | Distribution of polycyclic aromatic hydrocarbons in sediments from Yellow River Estuary and Yangtze River Estuary,China显示文摘Surface sediment samples collected from twenty-one sites of Yellow River Estuary and Yangtze River Estuary were determined for sixteen priority polycyclic aromatic hydrocarbons (PAHs) by isotope dilution GC-MS method. The total PAH contents varied from 10.8 to 252 ng/g in Yellow River Estuary sediment, and from 84.6 to 620 ng/g in Yangtze River Estuary sediment. The mean total PAH content of Yangtze River Estuary was approximately twofold higher than that of Yellow River Estuary. The main reasons for the difference may be the rapid industrial development and high population along Yangtze River and high silt content of Yellow River Estuary. The evaluation of PAH sources suggested that PAHs in two estuaries sediments estuaries were derived primarily from combustion sources, but minor amounts of PAHs were derived from petroleum source in Yellow River Estuary. PAHs may be primary introduced to Yellow River Estuary via dry/wet deposition, wastewater effuents, and accidental oil spills, and Yangtze River Estuary is more prone to be affected by wastewater discharge. | HUI Yamei ZHENG Minghui LIU Zhengtao GAO Lirong | 2009 | Journal of Environmental Sciences2009，21，12： | 24 |
| 2 | Preparation of Fe_2P/Al_2O_3 and FeP/Al_2O_3 catalysts for the hydrotreating reactions显示文摘A 60%Fe/Al_2O_3 catalyst was prepared by the co-precipitation method.It was reduced by H_2 to produce metallic Fe,which was then sulfided by CS_2 to Fe_(0.96) S and Fe_3S_4 or phosphided by triphenylphosphine(PPh3) in liquid phases to Fe2 P and Fe P.It was found that the iron sulfides(Fe0.96 S and Fe_3S_4) exhibited the low activity for the hydrodesulfurization(HDS) reactions.The HDS activity was also low on the Fe(metal)/Al_2O_3 and Fe_2 P/Al_2O_3 catalysts since they were converted into Fe0.96 S and Fe_3S_4 during the HDS reactions.In contrast,the FeP/Al_2O_3 was found to be stable and active for the HDS reactions.In particular,Fe P/Al_2O_3 possessed significantly smaller Fe P particles than Fe P/C,leading to the significant higher HDS activity of FeP/Al_2O_3 than Fe P/C. | Yamei Yuan Jiayou Zhang Hui Chen Qiumei Hou Jianyi Shen | 2019 | Journal of Energy Chemistry2019，28，2： | 2 |

| 5 | The genome sequence of star fruit(Averrhoa carambola)显示文摘Oxalidaceae is one of the most important plant families in horticulture,and its key commercially relevant genus,Averrhoa,has diverse growth habits and fruit types.Here,we describe the assembly of a high-quality chromosomescale genome sequence for Averrhoa carambola(star fruit).Ks distribution analysis showed that A.carambola underwent a whole-genome triplication event,i.e.,the gamma event shared by most eudicots.Comparisons between A.carambola and other angiosperms also permitted the generation of Oxalidaceae gene annotations.We identified unique gene families and analyzed gene family expansion and contraction.This analysis revealed significant changes in MADS-box gene family content,which might be related to the cauliflory of A.carambola.In addition,we identified and analyzed a total of 204 nucleotide-binding site,leucine-rich repeat receptor(NLR)genes and 58 WRKY genes in the genome,which may be related to the defense response.Our results provide insights into the origin,evolution and diversification of star fruit. | Shasha Wu Wei Sun Zhichao Xu Junwen Zhai Xiaoping Li Chengru Li Diyang Zhang Xiaoqian Wu Liming Shen Junhao Chen Hui Ren Xiaoyu Dai Zhongwu Dai Yamei Zhao Lei Chen Mengxia Cao Xinyu Xie Xuedie Liu Donghui Peng Jianwen Dong Yu-Yun Hsiao Shi-lin Chen Wen-Chieh Tsai Siren Lan Zhong-Jian Liu | 2020 | Horticulture Research2020，7，1： | 1 |
| 6 | Comparative analysis of plastomes in Oxalidaceae:Phylogenetic relationships and potential molecular markers显示文摘The wood sorrel family,Oxalidaceae,is mainly composed of annual or perennial herbs,a few shrubs,and trees distributed from temperate to tropical zones.Members of Oxalidaceae are of high medicinal,ornamental,and economic value.Despite the rich diversity and value of Oxalidaceae,few molecular markers or plastomes are available for phylogenetic analysis of the family.Here,we reported four new whole plastomes of Oxalidaceae and compared them with plastomes of three species in the family,as well as the plastome of Rourea microphylla in the closely related family Connaraceae.The eight plastomes ranged in length from 150,673 bp(Biophytum sensitivum)to 156,609 bp(R.microphylla).Genome annotations revealed a total of 129e131 genes,including 83e84 protein-coding genes,eight rRNA genes,37 tRNA genes,and two to three pseudogenes.Comparative analyses showed that the plastomes of these species have minor variations at the gene level.The smaller plastomes of herbs B.sensitivum and three Oxalis species are associated with variations in IR region sizes,intergenic region variation,and gene or intron loss.We identified sequences with high variation that may serve as molecular markers in taxonomic studies of Oxalidaceae.The phylogenetic trees of selected superrosid representatives based on 76 protein-coding genes corroborated the Oxalidaceae position in Oxalidales and supported it as a sister to Connaraceae.Our research also supported the monophyly of the COM(Celastrales,Oxalidales,and Malpighiales)clade. | Xiaoping Li Yamei Zhao Xiongde Tu Chengru Li Yating Zhu Hui Zhong Zhong-Jian Liu Shasha Wu Junwen Zhai | 2021 | Plant Diversity2021，43，4： | 0 |
