共生藻

这会导致珊瑚白化。面对环境压力，珊瑚会排出生活在其细胞组织中，并为其提供颜色和能量的共生藻。

This causes bleaching . Under stress , the corals expel symbiotic which lives in their tissues and gives them their colour and energy .

地衣中酸性磷酸酶活性主要由共生藻所决定。

The activity of acid phosphatase in lichen was mainly dependent on the photobiont .

这让荧光珊瑚能够保护好他们的共生藻。

This gives fluorescent corals an edge in protecting the symbiotic algae they host .

本实验以3种海葵的共生藻为实验材料，探讨了共生藻的体外培养。

Symbiotic algae from three kinds of anemone were cultivated in medium in this study .

珊瑚主要是通过珊瑚与共生藻的生理适应机制以及更换共生藻基因型机制两种方式来适应环境胁迫的。

Corals can adapt to environmental changes by two mechanisms : physiological acclimatization and exchange of symbiotic algae .

浅水珊瑚的美丽色彩，部份是来自生存于珊瑚细胞内的共生藻。

Shallow-water corals owe their beautiful colors in part to symbiotic algae , which live inside the coral cells .

有关共生藻的研究，离体培养是进一步研究的基础和非常关键的环节，也是一个难点。

Culturing symbiotic algae in some medium successfully is cornerstone and has great difficulty to the study of symbiotic algae .

结果表明，共生藻主要存在于触手组织的内胚层，被宿主细胞的空泡包围。

The results showed that symbiotic algae were found predominantly in the endoderm of the tentacles and were located within vacuoles in host cells .

总体而言，共生藻密度与单位面积叶绿素a含量对温度较为敏感。

In general , both the density of the symbiotic algae and the Chl . a content of the coral tissues are sensitive to temperature .

本研究以几种海洋无脊椎动物-共生藻的共生体为研究对象，从细胞水平、个体水平以及分子水平对共生规律进行了一些探讨，得到如下一些结果。

To explore the mechanism of symbiosis , some algal-invertebrate associations were studied from several aspects , including cell level , individual level and molecular level .

共生藻吸收无脊椎动物代谢产生的二氧化碳、磷酸盐、硝酸盐等，并转化为共生体所需要的营养。

These symbiotic algae absorb carbon dioxide , phosphate and nitrate produced by invertebrates and transform them into nutrition necessary to symbiont ( symbiotic algae and invertebrate ) .

研究结果表明：共生藻在体外较难培养，培养10小时后，共生藻的表面就会出现小的空洞，随着时间的延长，表面的空洞逐渐增大，并出现细胞内容物外溢的现象。

The results showed that it was very difficult to culture symbiotic algae in artificial medium . Some small holes occurred on the surface of symbiotic algae after being cultivated for 10 h. Holes were enlarged and some cell contents were discarded with extending cultivating time .

通过石蜡组织切片和扫描电镜组织切片观察了共生藻在3种海葵触手组织中的分布，通过透射电镜研究了共生藻在宿主细胞中的定位。

Distribution of symbiotic algae in the tissue of three kinds of anemone was studied by microscope and scanning electron microscope ( SEM ) . Localization of these symbiotic algae in the cell of the hosts was also confirmed using transmission electron microscope ( TEM ) .

共生藻的超微结构也有一些变化，饥饿3天的海葵含有正在分裂的细胞，其共生藻含有较多数目的线粒体，而饥饿45天与饥饿280天海葵体内的共生藻出现了较多的脂肪颗粒。

Some changes in the ultrastructure of symbiotic algae occurred . Symbiotic algae from anemone starved for 3 days contained some dividing cells and had more mitochondria than that from starved anemones for 45 days and 280 days . The latter algae contained some lipid grains .

目前梅衣科地衣中还未见有报道存在共生蓝藻，而且藻菌共生与生长基质的关系也未见报道。

Now there is cyanobacteria in Parmeliaceae which is not reported recently , furthermore , the relationship between algae-fungus symbiosis and growth matrix also has no reports .
