查询词典 nodulation

In order to discover acid-tolerant Rhizobium meliloti that can nodulate alfalfa high-effectively on acidic soil, researches were explored to isolate rhizobia from alfalfa nodules on acidic soil (pH5.2), methods based on the thesis of adaptive acid-tolerance response of the Rhizobia were adopted, six strains were isolated, which could grow on solid medium with pH4.8 steadily. In addition, the nodulation characteristics, growth curves and mean generation time under different acidity of the strains were examined.

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。

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。

Sinorhizobium fredii 042BS was isolated from root nodules of alfalfa from Xinjiang Region. Nodulation experiments showed that both soybean and alfalfa were nodulated by 042BS effectively.

费氏中华根瘤菌042BS分离自新疆的苜蓿根瘤，交叉结瘤试验发现它既可以在苜蓿上又能在大豆上结瘤固氮。16S rDNA PCR-RFLP分析表明，042BS与费氏中华根瘤菌模式菌株USDA205的4种限制性酶切图谱完全一致。

Twenty-eight prototrophic revertants of the tryptophan auxotrophs were obtained through spotaneous back mutation from colonies grown on synthetic medium plates or nodules of plants. Most of the revertants have resumed the nodulation abilities and enhanced nitrogen fixation activities as evidenced by darker green color, higher dry weight and more nitrogen contents in shoot than those of the wild type strain 8-1-4A did in pot experiments. However, noodulation abilities decreased to some extent and no significant differences were found in the mass of nodules compared with the parent strain.

通过自发回复突变，从培养平板和根瘤中分离到28个色氨酸原养回复突变型菌株，对其中25株进行植物盆栽试验证明其中24株菌的结瘤功能得到了恢复，而且固氮酶活性普遍比出发菌有所提高，其中41％达到极显著水平，18％达到显著水平，植株地上部分干重及含氮量也有不同程度的提高，唯有根瘤数比出发菌有所降低，其中23％降低达极显著水平，11％降低达显著水平。
