根瘤菌

Rhizobium could promote the growth of the plant and even facilitate the absorbability and the transportation of the PCBs in the plant.

接种根瘤菌明显促进植株的生长以及植株对PCBs的吸收和转运。

The levels of all identified metabolites are notably higher at day 11 and day 14. At day 21, the amounts of Asn and His were decreased, but Val, lactate, Ala, malate, succinate, GABA, choline,β-glucose, fructose, allantoid, Phe and formate were all increased. Enteric bacteria must overcome the acid environments in host organs to colonize the host.

结果表明：根瘤菌处理5d后苹果酸含量显著增加，7d时丙氨酸浓度降低而异亮氨酸、苹果酸、琥珀酸、GABA、胆碱、磷酸胆碱、β-葡萄糖、延胡索酸、组氨酸、苯丙氨酸、色氨酸含量显著增加。11d和14d的差别极为显著，所有已鉴定代谢物的含量都大大增高。

We also draw the conclusions from the review as follows:①RAPD, SSR and AFLP can be used to analysis the variation of peanut;②The deep generations of hybridized peanut can be identified by RAPD ;③Use RFLP and RAPD to draw the fingerprinting of peanut;④The research on Bradyrhizobiumsp Arachis;⑤The progress in the technique of RFLP and RAPD based on peanut research.

主要介绍了RFLP、RAPD、SSR、AFLP等四种分子标记技术的原理、方法、特点及其在花生上的应用现状：①RAPD、SSR、AFLP都可以分析花生品种的多样性；②RAPD技术可以对杂交后代进行鉴定；③利用RFLP、RAPD技术绘制花生指纹图谱；④利用分子标记技术研究花生根瘤菌；⑤基于花生的RFLP、RAPD技术的改进。

At the moment, a number of relevant genes in the bacteroid related to the symbiosis were activated, and the expressed quantity of protein remarkably increased.

为了探明这种改变是否与合成蛋白质的细胞器一核糖体有关，比较分析了苜蓿根瘤菌在自生和共生状态下核糖体蛋白的表达谱。

During the establishment process of symbiotic relation of alfalfa rhizobium with host plant, alfalfa rhizobium entered into host plant cell as self-growing state, and then transferred into bacteroid of symbiotic state through its differentiation development.

苜蓿根瘤菌在与宿主植物建立共生关系的过程中，以自生状态进入宿主植物细胞，经过分化发育转变为共生状态的类菌体。

Bacteroid A modified bacterial cell in a root nodule , typically a cell of the bacterium Rhizobium in the root nudule of a leguminous plant family Fabaceae .

类细菌：在根瘤中经过修饰的细菌细胞，比较典型的是在豆科植物根瘤中的根瘤菌。

Uses the soil bonsai to carry on the root nodule bacteria and the alfalfa highly effectiveparagenesis match experiment, in the simulation production practice the big field soil environment,conducts the research to the root nodule bacteria in soil compatibility.

采用土壤盆栽进行根瘤菌与紫花苜蓿高效共生匹配试验，模拟生产实践中大田的土壤环境，对根瘤菌在土壤中的适应性进行研究。

Viciae hurL gene formed nodules in wild-type amounts, indicating that hurL gene is required for nodulation. Although the function of hurL gene in inducing nodulation remains unknown, the results of this work revealed that in addition to the nod and exo genes located on Sym plasmid, the R. leguminosarum chromosomal hurL gene is also involved in controlling its capacity in inducing nodulation on host plant.

虽然目前对hurL基因影响豌豆根瘤菌诱导植物结瘤能力的机制并不清楚，但本文的研究结果首次证明：除位于共生质粒上的结瘤基因和胞外多糖基因外，豌豆根瘤菌在宿主植物上的结瘤还受到染色体基因hurL的控制。

However, the nodule could be induced by germfree liquid that filtered from the rhizobia, cultural medium. It is proposed that the some soluble substances excreted by the cultured rhizobia, can stimulate the plant to form the root nodules. Nevertheless, the nodules formed by this way can't produce haemachrome. So the nodules show light green or white. And there are starch in them.

但根瘤的形成还可由培养根瘤菌的无菌滤液诱导形成，这充分说明根瘤菌生长过程中分泌的某种可溶性物质具有刺激植物形成根瘤的作用，但这种根瘤由于不能形成豆血红蛋白而呈淡绿色或白色，且根瘤中有大量淀粉积累。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
