| 1 | Heterotrophic ammonium removal characteristics of an aerobic heterotrophic nitrifying-denitrifying bacterium, Providencia rettgeri YL显示文摘Bacterium Providencia rettgeri YL was found to exhibit an unusual ability to heterotrophically nitrify and aerobically denitrify various concentrations of ammonium (NH4+-N). In order to further understand its removal ability, several experiments were conducted to identify the growth and ammonium removal response at different carbon to nitrogen (C/N) mass ratios, shaking speeds, temperatures, ammonium concentrations and to qualitatively verify the production of nitrogen gas using gas chromatography techniques. Results showed that under optimum conditions (C/N 10, 30°C, 120 r/min), YL can significantly remove low and high concentrations of ammonium within 12 to 48 h of growth, respectively. The nitrification products hydroxylamine (NH2OH), nitrite (NO2-) and nitrate (NO3-) as well as the denitrification product, nitrogen gas (N2), were detected under completely aerobic conditions. | TAYLOR Shauna M | 2009 | Journal of Environmental Sciences2009,21,10: | 53 |
| 2 | 一株异养脱氮菌的脱氮性能及其影响因素研究显示文摘研究异养硝化过程中分离得到一株具有异养脱氮性能的菌株,经16S rRNA鉴定后为Providencia rettgeri菌属,命名为Providencia rettgeristrain YL。在实验室条件下,初步探讨了不同碳氮源、温度、pH值、摇床转速和微量元素对Providencia rettgeristrain YL菌株脱氮作用的影响,研究结果显示,Providencia rettgeristrain YL菌株在葡萄糖和氯化铵为碳氮源的培养基中生长最好,温度为30℃、pH值为7、摇床转速为120 r/min时具有最佳的脱氮效果,微量元素Mg2+最有利于Providencia rettgeristrain YL菌株的生长和脱氮。 | 黄珏 何义亮 赵彬 Shauna Taylor 张文英 | 2009 | 环境工程学报2009,3,3: | 5 |
| 3 | A Lesion-Mimic Syntaxin Double Mutant in Arabidopsis Reveals Novel Complexity of Pathogen Defense Signaling显示文摘损害模仿 Arabidopsis 异种, syp121 syp122,组成地表示表明小径的水杨酸酸(SA ) 并且有低穿入抵抗到粉的霉真菌。损害模仿显型的基因分析在植物扩展了我们规划房间死亡(PCD ) 的理解。在 syp121 syp122 表明基因的 SA 的 Inactivation 仅仅部分救损害模仿显型,显示另外的防卫贡献 PCD。整个染色体 transcriptome 分析证实了那知道的导致 SA 的抄本,以及众多的其它病原体反应抄本,在 syntaxin 基因的 inactivation 以后是起来调整的。syp121 syp122 的 suppressor 异种分析表明 FMO1, ALD1,和 PAD4 为损害开发是重要的。EDS1, NDR1, RAR1,和 SGT1b 的变异的等位基因部分也救了损害模仿显型,建议那变异的 syntaxin 基因刺激 TIR-NB-LRR 和 CC-NB-LRR-type 电阻。syntaxin 两倍大美人加强了粉的导致霉的象 HR 一样回答。发信号的这要求的功能的 PAD4 然而并非功能的 SA。然而,发信号的 SA 加强了 PAD4 依赖的象 HR 一样反应。四倍的异种的分析建议 EDS5 和 SID2 授与分开的 SA 独立的发信号功能,并且那 FMO1 和 ALD1 调停 NPR1 依赖的 SA 独立的信号。这些研究加亮多重小径的贡献到防卫和点到他们的相互作用的复杂性。 | Ziguo Zhang Andrea Lenk Mats X.

| 4 | Arabidopsis Heterotrimeric G-protein Regulates Cell Wall Defense and Resistance to Necrotrophic Fungi显示文摘Arabidopsis heterotrimeric G 蛋白质控制防卫回答到 necrotrophic 和脉管的真菌。在 G 子单元显示损害的 agb1 异种提高了危险性到这些病原体。G/AGB1 形式一与任何一个一 Arabidopsis G 子单元(1/AGG1 和 2/AGG2 ) 更暗淡的 obligate。因此,我们现在证明 agg1 agg2 加倍异种象到 necrotrophic 真菌 Plectosphaerella cucumerina 的 agb1 植物一样易受影响。阐明 heterotrimeric G-protein-mediated 抵抗的分子的基础,我们与 P 在接种之上执行了 agb1-1 异种和野类型的植物的比较 transcriptomic 分析。cucumerina。和 metabolomic 研究,这分析证明 G-protein-mediated 抵抗独立于为抵抗要求到 necrotrophic 真菌的防御小径,例如发信号的水杨酸酸, jasmonic 酸,乙烯, abscisic 酸,和导出色氨酸的代谢物,当这些小径没在 agb1 和 agg1 agg2 异种被损害。尤其是,在 agb1 植物的许多调整 mis 的基因与房间墙功能被联系,它也是在 agg1 agg2 异种的盒子。生物化学的分析和 Fourier 变换红外线(FTIR ) 从 G 蛋白质异种的房间墙的光谱学比在野类型的植物,和那异种墙有类似的 FTIR spectratypes 的表明木糖内容在 agb1 和 agg1 agg2 异种是更低的,它不同于野类型的植物的。这里介绍的数据在 Arabidopsis 有免疫力的回答和房间墙作文的规定的控制建议 G 和 G1/2 子单元的正规功能。 | Magdalena Delgado-Cerezo Clara Sanchez-Rodriguez Viviana Escudero Eva Miedes Paula Virginia Fernandez Lucia Jorda Camilo Hernandez-Blanco Andrea Sanchez-Vallet Pawel Bednarek Paul Schulze-Lefert Shauna Somervilleg Jose Manuel Estevez Staffan Persson Antonio Molina | 2012 | Molecular Plant2012,5,1: | 3 |
