| 1 | Fast increasing of surface ozone concentrations in Pearl River Delta characterized by a regional air quality monitoring network during 2006–2011显示文摘Based on the observation by a Regional Air Quality Monitoring Network including 16 monitoring stations, temporal and spatial variations of ozone(O3), NO2and total oxidant(Ox) were analyzed by both linear regression and cluster analysis. A fast increase of regional O3concentrations of 0.86 ppbV/yr was found for the annual averaged values from 2006 to 2011 in Guangdong, China. Such fast O3increase is accompanied by a correspondingly fast NOx reduction as indicated by a fast NO2 reduction rate of 0.61 ppbV/yr. Based on a cluster analysis, the monitoring stations were classified into two major categories – rural stations(non-urban) and suburban/urban stations. The O3concentrations at rural stations were relatively conserved while those at suburban/urban stations showed a fast increase rate of 2.0 ppbV/yr accompanied by a NO2 reduction rate of 1.2 ppbV/yr. Moreover, a rapid increase of the averaged O3 concentrations in springtime(13%/yr referred to 2006 level) was observed, which may result from the increase of solar duration, reduction of precipitation in Guangdong and transport from Eastern Central China. Application of smog production algorithm showed that the photochemical O3production is mainly volatile organic compounds(VOC)-controlled. However, the photochemical O3production is sensitive to both NOx and VOC for O3pollution episode. Accordingly, it is expected that a combined NOx and VOC reduction will be helpful for the reduction of the O3 pollution episodes in Pearl River Delta while stringent VOC emission control is in general required for the regional O3 pollution control. | Jinfeng Li Keding Lu Wei Lv Jun Li Liuju Zhong Yubo Ou Duohong Chen Xin Huang Yuanhang Zhang | 2014 | Journal of Environmental Sciences2014，26，1： | 51 |

| 3 | Sulfolobus tokodaii RadA paralog,stRadC2,is involved in DNA recombination via interaction with RadA and Hjc显示文摘Rad51/RadA paralogs found in eukaryotes and euryarchaea play important roles during recombination and repair,and mutations in one of the human Rad51 paralogs,Rad51C,are associated with breast and ovarian cancers.The hyperthermophilic crenarchaeon Sulfolobus tokodaii encodes four putative RadA paralogs and studies on these proteins may assist in understanding the functions of human Rad51 paralogs.Here,we report the biochemical characterization of stRadC2,a S.tokodaii RadA paralog.Pull-down assays revealed that the protein was able to interact with the recombinase,RadA,and the Holliday junction endonuclease,Hjc.stRadC2 inhibited the strand exchange activity of RadA and facilitated Hjc-mediated Holliday junction DNA cleavage in vitro.RT-PCR analysis revealed that stRadC2 transcription was immediately reduced after UV irradiation,but was restored to normal levels at the late stages of DNA repair.Our results suggest that stRadC2 may act as an anti-recombination factor in DNA recombinational repair in S.tokodaii. | WANG Lei SHENG DuoHong HAN WenYuan HUANG Bin ZHU ShanShan NI JinFeng LI Jia SHEN YuLong | 2012 | Science China(Life Sciences)2012，55，3： | 3 |

| 20 | Co-expression with RadA and the characterization of stRad55B, a RadA paralog from the hyperthermophilic crenarchaea Sulfolobus tokodaii显示文摘ST0838 (designed stRad55B) is one of the four RadA paralogs (or Rad55 homologues) in the genome of the hyperthermophilic crenarchaeon Sulfolobus tokodaii. The gene is induced by UV irradiation, sug-gesting that it is involved in DNA recombinational repair in this organism. However, this protein could not be expressed normally in vitro. In this study, thermostable and soluble stRad55B was obtained by co-expression with S. tokodaii RadA (stRadA) in E. coli, and the enzymatic properties were examined. It was found that stRad55B bound ssDNA preferentially and had a very weak ATPase activity that was not stimulated by DNA. The recombinant protein inhibited the strand exchange activity promoted by stRadA, indicating that stRad55B might be an inhibitor to the homologous recombination in this ar-chaeon. The results will be helpful for further functional and interaction analysis of RadA paralogs and for the understanding of the mechanism of recombinational repair in archaea. | SHENG DuoHong, LI MingFeng, JIAO JianDong, NI JinFeng & SHEN YuLong State Key Laboratory of Microbial Technology, Shandong University, Jinan 250100, China | 2008 | Science China(Life Sciences)2008，51，1： | 0 |
