查询词典 R.R.

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 theoretical studies on a series of a-hydrogen shift reactions between the alkylidene and alkylidyne organometallic molybdenum complexes R^3R^4Mo（CHR^1R^2） and R^3R^4Mo（= CH2）（= CR^1R^2）were carried out with the density functional theory B3LYP method.

AT-deficient plasma had significantly smaller R values compared with control, and dilution did not change R values in AT-deficient plasma. Celite activation eliminated dilution-associated changes in R values in control plasma but resulted in linear decreases R(2 = 0.88-0.96, P 0.0001 in alpha, A, and G in response to dilution.

结果显示对照组稀释后R、A、G值均明显下降，a值没有改变，而AT缺乏组与相应对照组相比R值明显降低，但稀释对其R并没有影响，硅藻土激活后使对照组中稀释造成R值下降的效果被消除，但使a、A、G值随稀释程度呈线性下降。

But Baumol has not reckoned with my contention that, all microeconomic price details aside, when we properly transform from rate-of-surplus-value accounting regime to actual rate-of-competitive-profit regime, we take an eraser and replace the a0-1(1+r*) m=1 relation that defines "the rate of surplusvalue, r*" by the alternative relation a0(1+R*)[I-a(1+R*)]-1 m=1 that defines the "competitive rate of profit, R*;" and literally nothing in the way of understanding of the latter's actual distribution relation is "revealed," is "uncovered" or is "laid bare" by the pre-eraser detouring.

但是鲍莫尔没有考虑到我的这一观点，将所有微观经济价格细节放在一边，当我们适当的将剩余价值率清算体制转化为实际的竞争利润率体制，我们就拿出一块橡皮并将a0-1(1+r*)m=1这一关系式替换成a0(1+R*)[I-a(1+R*)]-1m=1这一关系式，在关于后者的实际的分配关系的理解上，字面上没有任何东西被预先擦掉的弯路&揭示&、&揭露&或&暴露&出来。
