真菌共生

Symbiotic fungus from the nest play an important role in cellulose degradation, termite could obtain extrinsic cellulase for digesting the lignocellulose from food. The paper mainly compared the discrepance of cellulase activities from termites living different habit, and illustrated the secretion mechanism of cellulase in termite.

高等白蚁后肠缺乏原生动物，但其巢体上的共生真菌具丰富的纤维素酶，因此白蚁常通过取食巢体上的共生真菌来获得外源性纤维素酶，协助完成食物中纤维素的消化与吸收。

So far as we know, the ants which rely on fungi as a dominant food source belong to Attini and Solenopsidini, while most attine cultivar fungi are members of genus Leucoagaricus and Leucocoprinus (Basisiomycotina: Agaricales: Lepiotaceae), with a minority belonging to members of Ascomycotina and Deuteromycotina.

蚂蚁与真菌间的共生关系已具有长达5000多万年的协同进化历史，迄今已知的与真菌共生的蚂蚁主要为爱特蚁族和火蚁族的种类，而蚂蚁培养的真菌主要属于担子菌亚门伞菌目环柄菇科白环蘑属和白鬼伞属，少数种类属于子囊菌亚门和半知菌亚门。

The AMF spore average density was 24.88 per 20 g soil , the species richness was 1.94 per soil sample, the species diversity index was 2.56, and the species evenness was 0.65. Glomus, but they all were of prominent genus in the investigation area and Acaulospora, Scutellospora were of common genus while Entrophospora was rarely found. In the 13 species AM fungi, G.mosseae was of prominent species, and G.geosporum, G.intraradices, G.etunicatum were of common speices, while the others were of rarely species. There were 87.5% sand fixation plant were infected with arbuscular mycorrhizal fungi, the highest spore density, the strongest infection strength of the whole roots and the best species richness belonged to Chenopodiaceae while Polygonacea was the lowest.

四属AM真菌中，Glomus为优势属， Scutellospora 、Acaulospora为常见属，Entrophospora则为稀有属；十三种AM真菌中，G.mosseae、G.geosporum分别为优势种、最常见种，G.intraradices，G.etunicatum为常见种，其余均为稀有种；五科固沙植物中，87.5%的植物能被菌根侵染，其中藜科植物孢子密度最高，整个根系侵染强度最强，种的丰度最高，蓼科植物孢子密度、整个根系侵染强度、种的丰度则最低；禾本科植物不仅具有最好的丛枝结构，且具有相对高的亲和性，能与12种AM真菌共生。

The results showed that at the beginning stage of being attacked by Chinesis white pine beetle and their symbiotic blue-stain fungus, PAL, PPO, SOD activities and MDA content significantly increased in the phloem of P. armandi, and decreased with the increase of the number of D. armandi and the attacking on the xylem and phloem of P. armandi from blue-stain fungus, then reached the minimum level in withering stage of P. armandi. But the contents of nutrition materials in the phloem, such as water, protein, glucide, fat, amylum and so on, declined with the infestation of D. armandi and symbiotic fungus. In summary, the resistance of physiology and biochemistry in the phloem of P.

结果表明，在华山松大小蠹和共生蓝变真菌危害初期，华山松韧皮部内的苯丙氨酸解氨酶、多酚氧化酶、超氧化物歧化酶活性均显著提高，丙二醛含量明显增加；但随着华山松大小蠹种群数量的增加和蓝变真菌对华山松韧皮部和木质部组织危害的加剧，韧皮部组织内的PAL、PPO和SOD活性逐渐降低，在枯立木阶段降至最低；与此同时，华山松韧皮部内的水分及蛋白质、糖类、粗脂肪、淀粉等营养物质含量，则随华山松大小蠹和共生蓝变真菌危害的加剧而不断减少。

Arbuscular mycorrhizal symbiosis is the mutualistic association between AM fungi and most terrestrial plants: the plant roots offer carbohydrates to the fungi; in return, the fungi assist the plants with uptake of mineral nutrients, particularly phosphate, from soil, and their subsequent transfer to the root cortical cells.

南京农业大学资源与环境科学学院，南京 210095摘要丛枝菌根(arbuscular mycorrhizal， AM)共生是丛枝菌根真菌与大多数陆地植物的根系之间形成的一种互利共生关系。植物给菌根真菌提供碳水化合物；作为回报，菌根真菌能够增强植物对矿质营养元素的吸收。

But when we examined the structure of cultivar of D. huoshanense, endomycorhiza was founded unexpectedly. And in the wild type of D. huoshanense, fungi was also founded in its stems and leaves. So the author thought that endomycorhiza is not only located in the roots of Dendiobium plants, but also exists in other organs of plants, including stems, leaves. As plant produces seeds, mycorhiza could enter into the cells of seeds. When mature seeds germinate in media, the endomycorhiza enter into the roots of cultivar.

石斛属植物与真菌共生，根为菌根，作者在研究霍山石斛组织培养型结构时发现，组织培养苗的根部也分布有真菌，而且在野生霍山石斛的茎、叶中发现有真菌，作者因而指出，真菌并不是完全分布在根部，而是遍布于整个植物体，推测植物形成种子时，真菌进入种子，所以在组织培养时，真菌随着种子的萌发，进入植物体根部。

Orks are green-skinned and green-blooded, a side effect of their symbiotic relationship with fungi.

Orks拥有绿色的皮肤和绿色的血液——他们和真菌共生的一个副作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
