These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1~N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

During the last decade, many studies have hypothesized that the MADS-box proteins could form specific dimers, which would be further assembled into tetrameric complexes to have more functions. In order to prove whether BCFMADS and CCFMADS genes can interact with each together to form either homodimer or heterodimer, we used an in vitro approach to analyze protein expressions for both genes.
MADS-box基因中,基因并不会单独的表现,而是透过形成同质二元体、异质二元体或是蛋白质复合体来表现其基因的功能性,因此本研究为欲证实BCFMADS以及CCFMADS基因间可否形成同质二元体或是异质二元体,乃利用E。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.
通过研究,我们提出了初步的NodD操纵子激活模型:第一,四聚体是NodD蛋白的功能单位,它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子;第二,小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体,在我们的模型中,NodD四聚体缩小其V形主体的弯折角,进而缩短其DNA结合功能域的间距;第三,小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用,NodD的构象改变由蛋白质经其双铆钉位点传递给DNA;第四,只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物;第五,不排除NodD与RNA聚合酶可能有直接的相互接触位点,不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物,但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。
