根瘤菌

So it is held that inoculation of bean crops with appropriate rhizobium is an approach to further promoting the merits of N nutrition of the legumious/gramineous intercropping system.

因此，本研究认为豆科作物接种合适的根瘤菌，是进一步提高豆科/禾本科作物间作系统氮营养间作优势的又一重要途径。

In R.trifolii, matABC operon participates in malonate metabolism, and regulated by GntR transcription regulator MatR.

在三叶草根瘤菌中， matABC操纵子参与丙二酸的代谢，受到GntR转录调控因子MatR调控。

Rhizobia that nodulate the same hosts belong to a cross inoculation group.

能使相同寄主结瘤的根瘤菌属于同一互接种族。

It was also proved that the strain HN01DNL and TA11DNL could migrate as far as 25-30cm to the near soybean plant root and nodulate in the soil and sand microcosms.

本研究结果表明单独施用所构建的重组大豆根瘤菌于田间土壤时，未检测到抗性向其它土壤微生物的转移，HN01DNL已获准在2000年进行3000亩规模的环境释放。

The strain XZ-SX01-6 was chosen to perform cross-nodulation experiments with 6 legume plants. The results showed that the rhizobium from the broadbean can only nodulate with broadbean and pea.

另外分离自山西的菌株普遍表现出耐低温的特性；选取代表菌株XZ-SX01-6与六种豆科植物进行交叉结瘤试验，试验结果表明蚕豆根瘤菌的宿主专一性较强，除与蚕豆自身结瘤外，只与豌豆结瘤，与菜豆形成白色的无效瘤。

To prove the capability of 042BS to nodulate both soybean and alfalfa, constitutively expressed green fluorescence protein gene (gfp carried by pMP2444) was introduced to 042BS, and the recombinant strain 042BSG was obtained. The reisolates from nodules of the soybean and alfalfa inoculated with 042BSG were observed using the confocal laser-scanning microscope, and the expressions of gfp were detected, respectively.

将其接种保定苜蓿和北引1号大豆，并重新分离出根瘤菌，在激光共聚焦荧光显微镜下检测，可以清楚地观察到标记基因的表达，从而确证了042BS能同时在苜蓿和大豆上结瘤。

After the selection from one to three generations, several mutants were obtained. The major mutants included non-nodule mutants (18 lines) which failed to nodulate after inoculated with rhizobia for two weeks, ineffective nodulation mutants (9 lines) which had less uneven and white or transparent nodules, an abnormal leaf and flower mutant which was dwarf without stipules, abnormal flowers and less nodules, and a slender mutant with a thin stem and smaller leaves.

从种植的三代植株中，筛选到多种共生固氮根瘤的突变体，其中不结根瘤突变体18个株系，表现为接种根瘤菌两周后无根瘤形成；结无效根瘤突变体9个株系，表现为根瘤数目少且分布不均匀，根瘤呈白色，有些为半透明；花叶形态异常突变体1个株系，表现为除根瘤数目少外，植株矮小、托叶消失、花形态异常；纤细突变体1个株系，表现为除根瘤数目少外，植株变小、茎细叶小。

After the lectin gene is transferred from one type of legume into another, the latter could be finally infected and nodulated by the rhizobial bacteria that originally only harbor in the former legume.

将一种豆科植物的凝集素基因转化到另一种豆科植物后，再接种前一种豆科植物的根瘤菌，可以使其被侵染和结瘤。

The swainsonine mainly originated from the metabolism of Oxytropis endophyte, and its concentration was related with the nitrogen fixation of nodule, but not genetic characteristics.

棘豆中苦马豆素主要来源于内生菌的代谢产物，其含量与根瘤菌固氮作用有密切关系，而与遗传无关。

The experiment results indicate that logarithmic growth phase,resuscitative buffer Ⅴ,electrotransfection buffer Ⅳ,23kv/cm and 200 resistance are regarded the best electrotransfection condition of Sinorhizobium meliloti.

结果表明细胞的对数生长初期、复苏缓冲液Ⅴ、电转缓冲液Ⅳ、23 kv/cm和200Ω适合作为苜蓿中华根瘤菌电转的条件。

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

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
