The GPA1 gene was obtained via PCR amplification and was cloned in the two-hybrid DNA binding domain vector pGBKT7 The combinant plasmid was designated as pGBKT7-Ga.β-galactosidase assay indicatedthat Got did not have the property of self-activation. After pGBKT7-Ga was transformed to yeast pJ69-4A, we transformed Arabidopsis vegetative tissue two-hybrid cDNA library plasmids to yeast pJ69-4A containing pGBKT7-Ga.

通过PCR扩增得到GPA1基因并将其克隆到双杂交DNA结合域载体pGBKT7中，得到的重组质粒命名为pGBKT7-Gα，β—半乳糖苷酶活性鉴定表明Gα不具有自激活特性，将其转化到酵母菌pJ69-4A中，再以此为受体菌转化拟南芥绿色营养组织cDNA文库质粒。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

Methods The Cynomorium polysaccharide and Cynomorium water extract were extracted and prepared chewable tablets. Wistar rats were randomly divided into normal control, aging model, VitE, Cynomorium polysaccharide chewable tablets and Cynomorium water extract chewable tablets groups.

After drug intervention, the proliferation activity of rat spleen lymphocytes stimulated by ConA was detected by MTT assay and the spleen index was measured. The pathological morphological changes of spleen were observed. The activity of superoxide dismutase, the content of malondialdehyde and nitric oxide in serum of rats were detected.
