There are three copies of R fragment in the S mt-genome, and each copy contains two closely adjacent open reading frames: orf355 and orf77. Among these three copies two BamHI fragments were cloned, and the sequence analysis showed that cox1 and cox2 gene lies upstream of the R region in each fragment, respectively. However, they locate in different strands and head to head with R. In this study, we found that:(1) The expression of cox1 and cox2 is not affected by the transcription of R region;(2) The two copies of R region transcribe in large amount in the microspores, and produce transcripts of 1.6kb and 2.8kb, respectively, in the sterile microspores; However, the abundance of these two transcripts is reduced in the fertility restored microspores, realized through the mRNA decay, and this reduction occurs at the uninucleate microspore stage;(3) In the sterile microspores, the 5 terminus of the 1.6kb transcript contains a palindrome region that can fold into a stem-loop.
本研究发现:(1) cox1和cox2的转录没有受到R区转录的影响;(2)两个拷贝的R区在在不育花粉中高丰度表达,其转录本大小分别为1.6kb和2.8kb;而在育性恢复的花粉中,这两个转录本的丰度被大大降低,进一步分析表明这一结果是通过mRNA分子的降解途径来实现的,此降解过程发生在单核花粉期;(3)在不育花粉中,1.6kb转录本的5′末端具有一段可形成茎环结构的迴文对称序列,而在可育花粉中,其5′末端短缺了9个碱基;(4)在不育花粉和育性恢复的花粉中,R区转录本的加尾位点都集中位于一个3′茎环结构之后;(5)不管是在不育花粉还是育性恢复的花粉中,orf77区域内均在第52位和100位核苷酸处发生了不同频率的C向U的编辑,从而形成UGA终止密码;(6)不管是orf55-orf77的成熟转录本还是转录前体分子,都已被加上了Poly尾巴,表明已进入降解途径;在以上实验结果的基础上,本研究对S型CMS花粉育性的恢复机理进行了如下推测:在不育花粉和育性恢复的花粉中,orf77区域内均发生了终止编辑,即由RNA编辑产生了提前终止密码子。

The PSCA_3 fragment was selected for its superior expression level in eukaryotic cells.Then the sig-PSCA_3-Fc-GPI genetic fragment was cloned into pVAX1-neo-IRES-GM/B7 vector to construct the final immunological inhanced DNA vaccine pVAX1-PSCA_3-FcGB. Immunofluorescence and flow cytometry were used to confirm the expression of PSCA_3 fragment by transfected into Cos7 cell.Finally,the anti-tumor effect of pVAX1-PSCA_3-FcGB was tested in murine prostate cancer model generated by RM-1 cell line.The animal was immunized with pVAX1-PSCA_3-FcGB DNA vaccine by intramuscular injection plus electroporation,pVAX1 and pVAX1-PSCA_1-FcGB plasmid were used as control.The inhibitory effect of tumor was investigated by observion of forming time,volume and inhibition ratio of tumor.Results:DNA sequencing conformed that the heterological PSCA fusion antigen fragment which was synchronized by overlapping-extending-PCR,was consistent to design.Enzyme digestion analysis showed that the 1 to 4 copies heterological PSCA fusion antigen fragments were constructed successfully.
