The cloned Buchnera groEL genes of Schizaphis graminum and Rhopalosiphum maize were ligated into pBV221,pET30a and pTrcHisA expression vector for construction of pBVRM,pBVSG, pETRM,pETSGPR,pTrcRM and pTrcSG. They were transformated into E. coli BL21(DE3),DH5a and JM109 for studying their expression.

The extra pronuclear of triploid zygotes after IVF is from sperm and the zygotes have no implantation value.

IVF后3PN卵子中多余的原核多为精子来源，没有移植价值；ICSI后3PN中多余的原核非精子来源，ICSI后3PN中二倍体率与IVF相比显著增高，在患者ICSI后无2PN卵子时可考虑行植入前遗传学诊断。

In this study, a new horizontal microinjection system has been established to solve these problems. Because the average time per pronuclear embryo by microinjection has been significantly shortened with the horizontal system, the cleavage rate and 16-cell rate of those microinjected embryos increased markedly.

为了解决这些问题，本研究有针对性地设计了新型的水平微注射系统，利用此系统，可明显缩短常规注射原核胚的平均时间，注射后原核胚的分裂率、8-16细胞胚胎发育率也明显提高。

Methods: Total RNA was extracted from esophageal carcinoma tissue, the primer containing special enzyme was designed, NY-ESO-1 fragment was amplified by RT-PCR, and then was cloned into the expression vector pET-15b by LP Recco PCR Cloning. The recombinants plasmid pET-15b-NY-ESO-1 were identified by restriction endonucleases digest analysis and sequence analysis.

In a word, we extracted first cotyledon of buckwheat total RNA, by method of RT-PCR and 3RACE, get the C terminal cDNA sequence of PI from Ukraine buckwheat, and do some bioinformatics analyse on this cDNA sequence of PI from buckwheat, such as gene characteristics, expression mode. All of this will be help for the forward research on functional protein and high performance of procaryon expression or eukaryon expression.

综上所述，我们利用RT-PCR和3′RACE技术首次从吉乌一号甜荞第一对子叶中克隆获得荞麦蛋白酶抑制剂基因并对其基因特性、表达模式进行生物信息学分析，同时构建了该基因序列羧基端原核表达载体，为今后进一步研究荞麦功能性蛋白的分子机制及高效原核、真核表达载体的构建奠定了基础。

Early cleavage rate,embryo quality,the rate of blastocyst,implantation and pregnant rates from these zygotes were observed,and the transferred embryos were selected according to the pronuclei orientation and early cleavage time.
