    Abstract Resting cells represent a survival strategy employed by diatoms to endure prolonged periods of unfavourable conditions. In the oceans, many diatoms sink at the end of their blooming season and therefore need to endure cold and dark conditions in the deeper layers of the water column. How they survive these conditions is largely unknown. We conducted an integrative analysis encompassing methods from histology, physiology, biochemistry, and genetics to reveal the biological mechanism of resting-cell formation in the model diatom Thalassiosira pseudonana. Resting-cell formation was triggered by a decrease in light and temperature with subsequent catabolism of storage compounds. Resting cells were characterised by an acidic and viscous cytoplasm and altered morphology of the chloroplast ultrastructure. The formation of resting cells in T. pseudonana is an energy demanding process required for a biophysical alteration of the cytosol and chloroplasts to endure the unfavourable conditions of the deeper ocean as photosynthetic organisms. However, most resting cells (> 90%) germinate upon return to favorable growth conditions.

    Abstract: 采用形态观察、16S rDNA序列和部分特异基因排列分析鉴定从植物根际土壤中分离的1株根际细菌HNA3；采用平板对峙试验和抑菌率计算方法测定其对供试植物病原真菌的拮抗谱和拮抗能力；通过摇瓶发酵和酸沉淀方法研究相关抗菌活性物质的产生条件及其分离方法；采用表面活性检测和有关功能编码基因的序列分析初步鉴定抗菌活性物质成分的性质。结果表明：HNA3菌株为1种解淀粉芽孢杆菌Bacillus amyloliquefaciens；BPY（牛肉膏蛋白胨酵母粉）培养基是适合HNA3生长和产生相关抗菌活性物质的适宜培养基； ... ...

    Abstract 采用形态观察、16S rDNA序列和部分特异基因排列分析鉴定从植物根际土壤中分离的1株根际细菌HNA3；采用平板对峙试验和抑菌率计算方法测定其对供试植物病原真菌的拮抗谱和拮抗能力；通过摇瓶发酵和酸沉淀方法研究相关抗菌活性物质的产生条件及其分离方法；采用表面活性检测和有关功能编码基因的序列分析初步鉴定抗菌活性物质成分的性质。结果表明：HNA3菌株为1种解淀粉芽孢杆菌Bacillus amyloliquefaciens；BPY（牛肉膏蛋白胨酵母粉）培养基是适合HNA3生长和产生相关抗菌活性物质的适宜培养基；活性物质存在于发酵除菌液中，可通过酸沉淀方法分离获得。活性物质具有较高的稳定性和抗逆性，属于脂肽类物质。本研究结果表明HNA3具有较广谱的拮抗植物病原真菌的能力，具备研发成为一种表面喷施型微生物杀菌剂的特性和应用前景。

    Abstract Adult mosquito surveillance was conducted using black light traps in August of 2006 and 2007 at Wangging county and Yanji city, Jilin Province, China to identify the distribution of anopheline mosquitoes in northern China. A total of 2459 female mosquitoes comprising three genera and eight species including Anopheles (Anopheles) lesteri, An. (Ano.) kleini, An. (Ano.) pullus, Culex inatomii, Cx. orientalis, Cx. pipiens, Cx. bitaeniorhynchus and Aedes vexans nipponii were collected. The most commonly collected species was An. kleini which had not been previously reported from China. Anopheles sinensis sensu stricto is commonly collected throughout China, but was not collected from these areas.
