根瘤菌

The book covers the latest advances of the fields of perception, transduction and responses to most biotic and abiotic signals met in a plant life, including light perception and transduction, wound- and mechanical signalling, the role of active oxygen species in plant signal transduction, heat stress signalling, cold acclimatation, dehydration, salt stress, recognition and signalling in interactions between plant and bacteria, fungi, viruses, as well as Rhizobia-legumes interactions, rhizospheric signals, ectomycorrhizal symbiosis, and plant-insect interactions.

该书内容覆盖了植物生命对大部分生物与非生物信号感知，传导和反应，包括光感知和传导，损伤和机械信号传导，活性氧在植物信号传导中的作用，热胁迫信号传导，冷适应，脱水，盐胁迫，植物与细菌，真菌，病毒相互作用中的识别和信号传导，以及根瘤菌与豆类的相互作用，球形根瘤菌的信号，外生菌根共生现象，和植物与昆虫之间的相互作用。

In order to verify the results of numerical taxonomy, Besides the examined strains in numerical taxonomy, 6 strains isolated from Caragana sp were analyzed by SDS-PAGE of the whole-cell protein.

本论文简要回顾了生物的界级分类学说，综述了根瘤菌分类的历史和研究现状，描述了根瘤菌分类的方法。

In the unsterilized soil, the colonization of JMC1402P was affected by the physical and chemical factors of soil, and the aboriginal microbe would compete with it.The safety of releasing JMC1402P to the surrounding was tested, the design was as follows: mixing JMC1402P and R. huakuii JS5A16L, JMC1402P and Pseudomonas fluorescens Pf.X16L2 in filterable membrane, sterilized soil and unsterilized soil.

JMC1402P标记菌株释放环境的安全性研究表明，当JMC1402P与华癸中生根瘤菌JS5A16L、荧光假单胞菌Pf.X16L_2混合培养在微孔滤膜上、灭菌盆装土及田间三个环境中时，未检测到华癸中生根瘤菌JS5A16L和荧光假单胞菌Pf.X16L_2中有gfp基因编码的绿色荧光蛋白的存在，在X-GlucA作用下亦没有带有gusA基因的发光菌落。

But the application of inoculant in field was blocked as the problem of nodulation competitiveness between inoculant strains and indigenous strains was not been solved completely.

尽管人们对这一问题已进行了大量的研究，但与根瘤菌结瘤基因的研究相比，我们对根瘤菌的竞争结瘤机制的认识仍非常有限。

For exploiting and making use of rhizobium species resources of planting leguminous trees in south China,the full_length 16S rDNA sequences of representative strains HJ06 and JJ06 of two rhizobia,isolated from Acacia crassicapa and A.cincinnata in south China,were determined.These sequences were compared with all known rhizobia and related bacteria and an unrooted phylogenetic tree was produced.

为了开发利用我国人工林豆科树种根瘤菌的种质资源，该研究对华南地区两个人工林豆科树种厚荚相思和卷荚相思的根瘤菌两个代表菌株HJ06和JJ06进行了16S rDNA全序列测定，将此全序列与根瘤菌各已知种及相关种的16S rDNA全序列进行了比较及聚类分析，得到系统发育树状图。

In comparison,the rhizobia in mature infected cells were larger,greater in number,varied in shape,and distributed throughout the nodule cells.The rhizobia in the mature cells also had poly-hydroxy butanoic acid and curapos.

成熟侵染细胞中，根瘤菌个体较大，数量较多，多呈棒状，少数为球形或椭球形，有很多根瘤菌还呈现明显的&T&形、&Y&形或&V&形，菌体占满了整个细胞，这时的根瘤菌大多数含有聚羟基丁酸和聚磷酸盐颗粒。

Arcuata; A large quantity of cells in fascicular nodules were infected by rhizobia; 16S rRNA gene sequence of T. arcuata shared the highest identities with that of Sinorhizobium meliloti, and this strain was able to tolerate relatively higher temperature and alkalin.

弯果胡卢巴结瘤需要较好的土壤及通气条件；根瘤簇生，瘤内含大量被根瘤菌侵染的细胞；弯果胡卢巴根瘤菌与苜蓿中华根瘤菌同源性最高，是一类较耐高温和强碱的菌株。

To determine if in a drought environment there was an adaptation for Acacia richii due to rhizobia, this experiment analyzed the accumulation of metabolites, such as proline, soluble sugar, and chlorophyll, after inoculation with SMD rhizobia separated from Tephrosia candida, YHH from Leucaena leucocephala and TWXS from A.

运用PEG-6000高渗溶液模拟干旱胁迫实验，测定台湾相思Acacia richii接种不同根瘤菌后体内部分生化物质的变化趋势，并探讨接种不同根瘤菌后对体内游离脯氨酸、可溶性糖和叶绿素积累的影响，从而为筛选更有利于台湾相思在干旱环境下生存的根瘤菌提供支持。

In addition, field experiments were carried to examine influence on lucernes growth, yield and quality by applying calcium and inoculating acid-tolerant R.

并通过田间试验，检测施Ca~(2+)和接种耐酸苜蓿根瘤菌对酸性土上紫花苜蓿生长及产量和品质的影响，以期建立一套耐酸苜蓿根瘤菌筛选和鉴定体系，为在西南紫花苜蓿新种植区接种高效耐酸苜蓿根瘤菌奠定基础。

The infection of rhizobia to rice was a dynamic process beginning with surface colonization of the rhizoplane (especially at lateral root emergence), followed by endophytic colonization within roots, and then ascending endophytic migration into the stem base, leaf sheath, and leaves where they developed high populations.

同时，根瘤菌还可以沿植物的表面从根到地上部分迁移。在植物的生殖生长阶段，内生根瘤菌仍然保持活动性，可以进入烟草子房的子房壁、胎座和胚珠内，暗示根瘤菌通过种子向子代垂直传播的可能性。

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.

实际上 我们已接通卫星可视电话了
