The major gene of CTXΦ receptor Tcp (toxin-coregulated pilus), tcpA, was detected by polymerase chain reaction analysis.

然而在本实验室研究中，于不含ctxAB基因的El Tor型霍乱弧菌中发现部分菌株含有RS基因同源序列，为此对这些菌株作CTXΦ基因组的进一步研究。

Neoproterozoic Baoxing Complex in middle to lower metamorphic grade, located in western margin of Yangtze Craton, consists mainly of metamorphic gabbroic, dioritic gneisses, tonalitic and granodioritic gneisses, and massive monzogranites The studies of petrochemistry and SmNd isotopes of Baoxing Complex reveal that the gabbroic and dioritic magmas came from a congenetic magma derived from the partial melting of spinel lherzolites in depletive mantle, and that the magma was intensively contaminated by crustal materials during its emplacement The tonalitic and granodioritic magma were derived from the partial melting of metamorphic basalts in the lower crust And the monzogranitic magma was formed from partial melting of metagreywacks Integrating the lithological association, their trace elements, SmNd isotopic characteristics and petrogenesis, the Baoxing Complex must likely have been emplaced in an island arc tectonic background at the Neoproterozoic active continental margin of Yangtze Craton

位于扬子克拉通西缘的新元古代宝兴杂岩主要由中低级变质的辉长质片麻岩、闪长质片麻岩、英云闪长质到花岗闪长质片麻岩和块状二长花岗岩组成。岩石地球化学和SmNd同位素特征表明，辉长质片麻岩和闪长质片麻岩为同源岩浆演化序列，原始岩浆起源于亏损地幔尖晶石橄榄岩的部分熔融，在上升和侵位过程中受到了地壳岩石强烈混染。英云闪长质和花岗闪长质岩浆形成于下地壳玄武质岩石部分熔融，而二长花岗质岩浆形成于杂砂岩的部分熔融。综合分析宝兴杂岩的岩石组合、微量元素和同位素特征，该杂岩体最有可能形成于新元古代活动大陆边缘火山弧构造背景，并可能经历了碰撞过程。

In the K-Na-Ca diagram, intermediate part has the tendency of toellite, and acid part has the tendency of calc-alkaline. According to the above data, its tectonic setting is thought to be continental arc.

其序列组成为石英闪长岩－花岗闪长岩／斜长花岗岩／英云闪长岩－二长花岗岩组合，二长花岗岩略多，地球化学特征具典型造山花岗岩特征，K-Na-Ca图解中性段具英云闪长岩趋势，酸性段呈钙碱性趋势，其构造坏境为大陆弧。

According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.

根据pfam资料库(Version 17.0)，我们整理同时拥有GGDEF和EAL功能性区域的蛋白质，这些蛋白质可以被区分成两种型态，在总数621个GGDEF-EAL中有高达606个是A型态，而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到，因此我们推测它可能是GGDEF-EAL的袓先，藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系，大部份的GGDEF-EAL会群聚在树型相近的位置，进一步比较在EAL树型上有邻近关系的蛋白质序列，根据他们的长度、与所包含的功能区域，我们找到了一些重制的演化痕迹，这样的结果指出，目前看到大多数的GGDEF 和EAL可能都是经过重制产生。

Repetitive element sequence-based PCR can be used to type vibrio parahaemolyticus, which is super to the serotyping method.

重复序列PCR可以用于副溶血弧菌临床分离株的分子分型研究，其分型敏感程度优于血型分型。

Previously, it was found that the hemolytic activity of the extracellular product of V. harveyi was involved in pathogenesis in salmonids, and the most pathogenic isolate, VIB 645, contains two closely related hemolysin genes, i.e. vhhA and vhhB.

已发现哈维氏弧菌对鱼类的致病性与其分泌的胞外产物中的溶血素相关，致病力最强的菌株VIB 645有2个碱基序列非常相似的溶血素基因，vhhA和vhhB。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
