| 1 | Spatio-temporal variations of the bacterioplankton community composition in Chaohu Lake, China显示文摘Despite considerable attention paid to Chaohu Lake in China, the dynamics of bacterioplankton community composition (BCC) on spatial and seasonal scales are poorly understood.In this study, water samples were collected from autumn 2006 to summer 2007 at five positions in Chaohu Lake with difierent trophic status.BCC of these samples was determined by both the PCR amplification of the 16S rDNA gene and the denaturing gradient gel electrophoresis (DGGE).The abundance and diversity of bacterioplankton communities at difierent sampling positions showed similar seasonal patterns.The BCCs in the samples varied substantially, and the pattern of changes indicated that the seasonal difierence might have a significant impact on the BCC's structure in the lake.Canonical correspondence anal-ysis (CCA) on the DGGE patterns and physicochemical parameters indicated that the temperature and the levels of 5-d biochemical O2 demand (BOD5), NH3-N, CODMn, total nitrogen, total phosphorous, and dissolved oxygen significantly infiuenced the BCC, and four of the seven variables were related to the level of eutrophication.Our results indicate that eutrophic status and season are the most infiu-ential factors in determining BCC in Chaohu Lake. | Chaoling Wei Sumin Bao Xinyan Zhu Xiangming Huang | 2008 | Progress in Natural Science:Materials International2008，18，9： | 9 |
| 2 | Effect of Epinephrine on the Settlement and Metamorphosis of Manila Clam Larvae显示文摘化学动机和 DDRT-PCR (微分显示颠倒 transcriptionPCR ) 被采用在马尼拉蚌幼虫的解决和变形上调查肾上腺素(EPI ) 的效果。化学动机证明 EPI 根本在马尼拉蚌幼虫的变形上有效果到某程度集中并且在设计的所有处理。动机的最重要的结果在 10 ~ 的集中被获得(-6) 摩尔 L^(-1) 并且为 4h,用六教材对的 .DDRT-PCR 证明基因表达式模式是相当不同的 betweenEPI 处理和控制。343 个扩大乐队总共被获得,在哪个之中,(19.53%) 67 是差别出现。因此, EPI 在眼睛点的基因表示上有效果幼虫的马尼拉蚌。EPI 是为马尼拉蚌的解决和变形 inducer,这能被假设。EPI 可以在膜上由绑定导致幼虫解决和变形到受体然后改变幼虫房间的基因表示。 | LU Sumin BAO Zhenmin LIU Hui FANG Jianguang | 2006 | Journal of Ocean University of China2006，5，2： | 3 |
