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。

After the identification of SARs in Attacus ricini rRNA gene, its rRNA gene and NTS were also found to have the ability binding with the nuclear scaffold of Saccharomyces cerevisiae. The 1kb NTS fragment which can bind clearly with nuclear scaffold of Attacus ricini was the chief fragment binding with yeast nuclear scaffold. This indicated the homology between this two kinds of SARs and provided an evidence for the evolutionary conservation of SARs.

在鉴定蓖麻蚕rRNA基因中具有骨架结合区域之后，利用体外结合的方法发现，蓖麻蚕rRNA基因及其非转录间隔区片段也具有与酵母核骨架结合的能力，尤其是能与蓖麻蚕核骨架结合的非转录间隔区1kb片段，也能明显地结合于酵母核骨架，这一结果表明二者的SAR顺序具有一定的同源性，为骨架结合区域具有进化保守性提供了又一证据。
