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 article adopted a new filtering-cloud composing technology used to monitoring drought,analyzed the property of Ts—NDVI characteristic space and the TVDI's indicating drought ability, put forward the TVDI compute model, grade standard, and the impact estimation method. The result indicated: 1 the decade-composed data obtained by the maximum surface temperature principle has better ability than the composed data obtained by the maximum NDVI on monitoring drought; 2 in the Ts-NDVI characteristic space,the dry side and the wet side almost are horizontal lines when the NDVI is on the small side, the temperature difference is about 45℃; 3 the TVDI has inequable level on monitoring drought as its value, the less TVDI indicates without drought occurrence, the bigger TVDI shows the drought certainly happened, the unsure drought conclusion mainly comes from the middle TVDI; 4 the monitored results of Sichuan hot-drought in 2006, obtained by the remote sensing and by the climate index, are basically consistent, the estimating error on the bearing drought crop area and on the drinking trouble population is within 10%.

Using this model three competence-deficient pneumococci, which was identified by PCR and transformation experiment, were constructed. It is found different strain has different bacterial optimal density for being induced into competence. The optimal density for strains 1, 2 and 22 was 0.1, 0.08and 0.07 respectively. The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.

With the rapid development of our country's photochemistry industry, the liquified petroleum gas is widely used. However, because of its unique flammable, explosive, virulent physic-chemical properties, it causes a series of burning, detonating accident which has occurred in domestic and foreign, which has caused the giant personnel casualty and property damage. Thus, it has been bad influence to the society. Therefore, it is necessary for the liquified petroleum gas store place to carry on the safety assessment and go on the grave accident sequential analysis research, regarding the effective science forecast, prevention and control significant accident occurrence, so it can reduce or avoid this kind of disaster accidents as far as possible, which has the important theory value and the practice significance for guarantee the liquified petroleum gas store place's safe operation.
