变形虫

The research suggests that lacustrine sedimentary testate amoebae, as an excellent indicator of environmental conditions, have valuable implications for environmental changes.

初步研究表明，有壳变形虫作为一种环境指示生物在湖泊沉积与生态演化研究中具有重要的应用价值。

In Dictyostelium amoebae, cell-type differentiation, spatial patterning, and morphogenesis are controlled by a combination of cell- autonomous mechanisms and intercellular signaling.

在变形虫盘基网柄菌中，细胞自主机制和细胞内信号的共同作用控制着细胞类型的分化、空间模式和形态发生。

"Researchers have recognized the potential of amoebae as a source of new viruses for a while," said Patrick Forterre, a microbiologist at the Pasteur Institute in Paris, France, who was not involved with the study.

拉奥尔特表示，这种被称作Marseillevirus的病毒，其基因组的组成成分&跟其他病毒的DNA有很大差异&，它与寄生在变形虫体内的其他巨型病毒和细菌等微生物进行过遗传物质互换。

Amorphous amoebic shapes alternate with sharply drawn lines, spots, and curlicues, all positioned on the canvas with seeming nonchalance.

毫无组织的变形虫图样随著拉长的线条，圆点以及花体而变化，在画布上排列出看似冷静的图案。

原质团由大量变形虫细胞聚集形成的细胞质的多核团，与粘菌的无性繁殖阶段的特性类似

The four protozoa had different changing patterns in rhizosphere and nonrhizosphere soil. About 90 times more Colpoda were determined in rhizosphere than in nonrhizospher at 52 days after sowing. There were more Anweba in rhizosphere than in nonrhizosphere at 74 days after sowing. Much more Bodo were found in rhizosphere at 32 days alter corn sowing. However, the number of the Bodo in rhizosphere soil was only 10% of that in the nonrhizosphere soil at 52 days after sowing. Rhizosphere always contains more Cercomonas than nonrhizosphere within the whole growing season of corn.

不同的原生动物的根际效应差异很大，肾形虫在抽雄期R/S比接近90；变形虫在吐丝时期表现出一定的根际效应；波豆虫在大喇叭口时期表现出比较强烈的根际效应，但在抽雄期则表现出十分强烈的负根际效应，根际土壤中波豆虫数量不到非根际土壤的10%；尾滴虫在玉米整个生育时期都表现出微弱的根际效应。

Three protozoa (Bodo edax, Colpoda cucullus, Amoeba proteus) were isolated from soil. The porous simulation with glass bead, soil column and root box incubation experiments were made to study the association of protozoa movement with phosphorus translocation and its influencing factors. The effects of protozoa on corn growth and corn straw mineralization were also involved. The results showed that protozoa movement in glass bead column was greatly controlled by the pore sizes. Bodo edax, about 5-7 m, could pass through the pores of 28-20 11 m in diameters. Colpoda cucullus (30-60 m) could move through the pores of 155~116 m. However, no Amoebaproteus(100~150 m) was found in the effluents from all the columns. All the three protozoa made 32P redistribution in soil column.

本研究利用土壤中常见的3种原生动物(梨波豆虫Bodo edax、僧帽肾形虫Colpoda cucullus、大变形虫Amoeba proteus)，通过玻璃珠孔隙模拟、土柱及根箱培养试验，研究3种原生动物运动与磷素运移之间的关系及其影响因素，以及原生动物对玉米磷素营养的影响，同时对3种原生动物在玉米秸秆分解中的作用做了初步的探索，研究结果表明：原生动物的运动与孔隙密切相关，Bodo edax(5～7μm)能够穿过28～20μm孔隙，Colpoda cucullus (30～60μm)只能穿过155～116μm的孔隙，而Amoeba proteus(100～150μm)不能从玻璃柱中流出。

内寄生变形虫的一个大目，能侵入消化道。

Later I went to the hospital to see him, he was cream-faced, lying on the sickbed flabbily like a mollusk amoeba, and actually he was vivid before.

后来我去医院看他，他脸色苍白，原本生龙活虎的小伙子像软体动物变形虫一样毫无生气的贴在病床上。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
