To investigate the pollution levels, occurrence and distribution of estrogens, six estrogens in the surface sediments of Wenyuhe River were analyzed quantitatively by GC/MS following ultrasonicated extraction including diethylstilbestrol, estrone(E1),β-estradiol(E2), 17α-ethynylestradiol(EE2), estriol(E3), and β-estradiol 17-valerate. Six estrogen concentrations ranged from 0.39-36.6ng/g and the mean concentration was 10.2ng/g.

It was found that there were 36 distinct differences in 184 protein spots. In-gel digestion and liquid chromatography mass spectrometry C LC-MS were made to analyze the protein SSP2801, and Mascot software was applied to identify the protein. The results showed the protein was large subunit of Rubisco, and its content in yellow mutant decreased distinctly, only about 26% of the comparison. Maybe it has relation to etiolation.

切耿其中差异最为明显的SSP2801位点蛋白进行胶内酶切、LC-MS分析，并应用Mascot软件检索鉴定，结果表明该蛋白组分为RUBP羧化酶的大亚基，其在突变体中含量明显减少，仅为对照的26％，表明突变体叶色黄化与RUBP羧化酶大亚基含量减少也有关系。

Result: The inductivity of leaves was the highest about 87.5%, followed with the stem section and leafstalk; The inductivity of nutrient medium such as MS, B5 callus was higher than the ones like H, SH and the White callus amended one; It was found that low-grade Phvalue benefits the growth of callus. The experiment result showed that different pH showed little difference in quality. The best condition of culture was 25 ℃in temperature. Conclusion: The best culture condition for callus was the leaves as explantation.
