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。

Of the eons of geological periods recorded in the stratifications of the earth: of the myriad minute entomological organic existences concealed in cavities of the earth, beneath removable stones, in hives and mounds, of microbes, germs, bacteria, bacilli, spermatozoa: of the incalculable trillions of billions of millions of imperceptible molecules contained by cohesion of molecular affinity in a single pinhead: of the universe of human serum constellated with red and white bodies, themselves universes of void space constellated with other bodies, each, in continuity, its universe of divisible component bodies of which each was again divisible in divisions of redivisible component bodies, dividends and divisors ever diminishing without actual division till, if the progress were carried far enough, nought nowhere was never reached.
349在地球的层理留下记录的太古以来的地质时代。隐藏在大地的洞穴里和能移动的石头底下、蜂巢和土墩子中那无数微小的昆虫类的有机生物:微生物、病菌、细菌、杆菌、精子;凭着分子的亲和之凝聚力而粘在一根针尖上那几万几亿几兆个多不胜数、肉眼看不到的微小颗粒;人类的血浆是一个宇宙,群集着白血球和红血球,每个血球又各自形成一个空虚的宇宙空间,群集着其他球体;各个球体连续性地也是由可分割的构成体形成的宇宙,各个构成体又可以分割成为几个能够进一步分割的构成体。就这样,分子与分母实际上在并未分割的情况下就不断地减少了。如果这个过程延续到一定时候,就永远在任何地方也不会达到零。

8Ps for native and NaBH〓 chemically modified reaction centers, and the transfer process from H〓 to the final electron acceptor Q〓 occurs in about hundreds of picoseconds. On the other hand, the energy transfer from excited B was obviously slowed down in the pheophytin-exchanged RC. By considering the change of free energy of ion pair P〓Phe〓, it could be expected there might exist alternative pathway of charge separation and electron transfer in pigment-exchanged reaction center. In addition, the influence of acid environment on the ultrafast dynamics of reaction center was also experimentally observed, which shows an evident difference from that of in native RC, and further investigation should be carried out to elucidate the origination.
在色素置换后的反应中心中,以B为起点的能量传递较天然RC的情况明显减慢,约在450fs左右,考虑到置换后的反应中心中P的自由能有所提高以及其仍然保持的光化学活性,这一较慢的能量传递也可能预示着还存在着其它的能量传递通道;另外,还对酸性处理的反应中心中的超快光动力学过程进行了尝试性的研究,发现由于色素分子的聚集以及蛋白环境的改变,BChl分子的激发态动力学过程有着明显不同于天然反应中心的情况。
