接合子

Over the last 10 years, antisense transgenic plants have been used as tools to address this and have revealed some unexpected findings. In this article, chloroplast tpi gene from spinach and tandem genes of chloroplast tpi gene from spinach and cytoplast fba gene from rice were transferred into filamentous, heterocystour cyanobacterium Anabaena sp.

将菠菜叶绿体tpi和水稻胞质fba的串联基因连接在光诱导的高效启动子PpsbA下游，克隆入pDC-08中构建了既能在大肠杆菌又能在蓝藻中表达的穿梭表达载体pDC-AT，并通过三亲接合转移转入鱼腥藻7120。

Methods Mating was conducted at 25℃ in saline between E.coli B101(RP4) and Salmonella aberdeen Kauffmann 50312 without stirring and the donor per recipient ratio was 1:3 constantly.

接合供体菌为大肠埃希菌-HB101(RP4)，受体菌为Salmonella aberdeen Kauffmann 50312，保持供、受体菌液浓度比例为1：3，25℃静止接合相应时间后，计算转接合子数。

Seven trans-conjugants were obtained by triparental cross and the nodulation tests of them are already in progress.

有关转移接合子的检测及植物盆栽试验正在进行之中。

Spirogyra and DESMIDS.

异形配子形成后，通过形成细胞间接合管，接合成为受精卵。

Though the gametic nucleus of normal cell didn't enter the amicronucleate cell, there were cytoplasm and organelle exchanges between two cells.

在接合对中，有小核细胞一方可以完成正常的减数分裂过程，既有配子核的形成、配子核的融合、配子核分裂，最终形成两个有小核的子细胞。

We also study the salt tolerance of transconjugants and Medicago Sativa plant.

本研究还检测了转移接合子和苜蓿的耐盐性。

The zygotes formed in conjugation are partial diploids or merozygotes.

接合形成的合子是部分二倍体，也叫做部分合子。

In the process of protein synthesis , a transfer RNA pairs with the mRNA codon.

在蛋白质接合的过程中，一个tRNA和mRNA密码子结合，那tRNA的反密码子核甘酸序列是？

Methods PCR screening and DNA sequence were used to determine the drug resistance genes associated with class I integron in 4 clinical strains of P.aeruginosa. The resistance genes were located by conjugated transfer experiments and the conjugations were studied by PCR method.

采用PCR扩增、DNA测序、DNA序列比对的方法对4株铜绿假单胞菌临床菌株携带的I类整合子相关基因进行解析，采用接合试验对该类整合子进行定位分析。

Methods PCR screening and DNA sequence were used to determine the drug resistance genes associated with class I integron in 4 clinical strains of P.aeruginosa. The resistance genes were located by conjugated transfer experiments and the conjugations were studied by PCR method.

整合子通过整合酶从环境中捕获耐药基因盒，并将耐药基因盒组装在一起，形成巨大的耐药基因多基因座；同时整合子及耐药基因盒可借助转化、转导及接合等方式在细菌中转移，使耐药基因广泛传播。
