固氮

And nodulation genes. We are interested in t he studies of int eraction between two symbiotic partner in

本实验室研究工作的主要方向是研究固氮基因、结瘤基因的结构和调节的分子机理，我们的兴

The issue whether starter N will increase nodulation and BNF is, however, complicated by several factors.

然而，"起动氮"是否会增加根瘤和生物固氮的问题是复杂的，它受多种因素影响。

Only when availability of N was increased through effective nodulation and BNF was there a response to applied P.

只有通过有效结瘤和生物固氮增加有效氮，施用磷肥才有效应。

The correlations between some characters of nodulation an...

不同年份间同一品种结瘤固氮存在着差异。

Nostoc flagelliforme is a kind of terrestrial filamentous nitrogen-fixing cyanobacterium distributing in arid and semiarid region of north-western China.It has a great economic and ecological value.So its fundamental study and application study for protection and development have been studied in different ways.

发菜是一种固氮陆生蓝藻，我国主要分布于西北干旱半干旱荒漠草原地带，具有重要的经济和生态价值，围绕发菜资源基础研究和保护开发的应用研究已广泛开展。

Its paragenesis effect is in turn makes the decency coal＞thevermiculite＞the pearlite.

其共生固氮效果依次为风化煤＞蛭石＞珍珠岩。

The study indicated that Choerospondias axillaries cropped with peanut wasn't optimum agroforestry model and it couldn't be extended blindly in subtropical China, that N〓-fixing shrub should be chosen to intercropped in farmland rather than tree, and that shade tolerance plant should be chosen to intercropped in orchard garden or man-made forest rather than photophilous plant in alley cropping system.

总之，花生南酸枣间作不是低丘红壤地区优化农林间作模式，不适宜盲目发展。在红壤农田系统中实行农林间作应优先选择固氮灌木，而非高大的乔木；在果园或人工林系统中实行农林间作应优先选择耐荫植物，而非花生等喜光作物。

The influence of sexual reproductive growth on nitrogenase activity during different seasons is due to the result of competition for photosynthate allocation between both.

我们从1984年开始对它的生态学特征进行调查，并对多种生态因子与根瘤固氮活性的关系进行了研究，现将结果报告如下。

Anoxygenic phototrophic bacteria are good model organisms used to study the origin and evolution of life, photosynthesis and nitrogen fixation mechanism.

不产氧光合细菌一直是研究生命起源与进化、光合作用和固氮机理的良好模式生物。

Under a suitable condition of crystallization, dark brown short rhombohedron crystals could be obtained from FeMoco-deficient MoFe protein (ΔnifE Av1) purified from a nifE deleted mutant DJ35 of Azotobacter vinelandii Lipmann grown in NH3-limited medium.

从限氨固氮培养基中培养棕色固氮菌缺失nifE的突变种DJ35中，分离纯化得到缺失FeMoco的钼铁蛋白(ΔnifE Av1)。在一定条件下结晶得到深棕色短斜四棱柱晶体。
