Soybean (Glycine max L. Merr.) is the world's foremost source of edible plant oil and proteins, meantime, the biologically active secondary metabolites such as saponins and isoflavones are benefit to human health. The objective of this study was to identify quantitative trait loci (QTL) and epistatic interactions associated with isoflavone, protein, and oil contents in soybean seeds. An F13 recombinant inbred line (RIL) comprising 474 lines was derived from a cross between Jindou 23 and Huibuzhi cultivars. SSR technique was employed for mapping of the QTLs. The QTLs for isoflavone, protein, and oil contents were analyzed and 23 QTLs were detected based on the constructed linkage map. Six QTLs for isoflavone content were localized in linkage groups J, N, D2, and G, eleven QTLs for oil content were localized in the linkage groups A1, A2, B2, C2, and D2, and six QTLs for protein content were localized in linkage groups B2, C2, G, and H1. The correlative analysis demonstrated that the isoflavone content had significant correlation with protein content, while significantly negative correlations was existed between oil and protein content, and significantly positive correlations was existed between protein and oil content. All these findings have laid an important basis for the marker assisted breeding in soybean. The phenotypic correlations of quantitative traits may be resulted from the correlation of the QTL controlling those traits. 相似文献

[目的]研究南板蓝根提取物对林可霉素注射液体外抑制金黄色葡萄球菌、大肠杆菌和枯草芽孢杆菌作用的影响。[方法]采用水提醇沉法和60%乙醇回流提取法提取板蓝根,分别测定板蓝根提取物及林可霉素的抑菌圈直径和最小抑菌浓度(MIC)。采用微量简化棋盘法,分别测定板蓝根提取物与林可霉素1∶1(V∶V)组合时的部分抑菌浓度指数(FIC),并以此来评价其抑菌作用。[结果]南板蓝根提取物与林可霉素均可抑制金黄色葡萄球菌、大肠杆菌和枯草芽孢杆菌,板蓝根提取物对林可霉素抑制这3种菌的作用分别为相加、相加和协同作用。[结论]南板蓝根提取物对林可霉素注射液体外抑制金黄色葡萄球菌、大肠杆菌和枯草芽孢杆菌均具有增强作用。 相似文献

[目的]对板蓝根和南板蓝根进行显微结构的研究。[方法]应用数码显微技术对市售不同来源的板蓝根和南板蓝根进行了显微结构的比较与分析。[结果]在两者的显微结构上,板蓝根中多见网纹导管、单粒淀粉、复粒淀粉、石细胞;南板蓝根中多见孔纹导管、具细小纹孔的薄壁细胞、单粒淀粉、钟乳体,这表明板蓝根和南板蓝根的显微结构差异显著。[结论]该研究所建立的板蓝根和南板蓝根显微结构特征可用于2种中药材的质量评价,同时也为全面研究板蓝根和南板蓝根的质量标准提供了科学依据及方法学的保障。 相似文献

[目的]了解红、绿、蓝3种不同基础色调的光对南板蓝生长的影响。[方法]运用易得到的材料自制滤光设备,采用不同光质的色光照射南板蓝,研究自然日光与红、绿、蓝3种色光对南板蓝生长的影响。[结果]红光最有利于种子发芽,自然日光次之,再次蓝光,绿光最后;生长量总体上以红光照射最大,自然日光次之,蓝光再次,绿光最后;定性比较叶面积大小顺序为自然日光照射、蓝光照射、红光照射、绿光照射;平均总分枝数大小排序为红光照射、蓝光照射、自然日光照射、绿光照射。[结论]不同的色光对植物不同部分的形成和生长影响不同,对植物内部不同的生化反应影响也不同,有针对地根据植物的现状进行光照干预调节,补充实际中自然光照的缺陷,才能促进植物更好地生长。 相似文献

为探索适于烟草根系蛋白质组学研究的样品制备方法,以栽培品种K326生长期根系为材料,比较了常规裂解液法、TCA/丙酮沉淀法、Trizol抽提法和酚法等4种总蛋白质的提取方法。对制备的样品进行聚丙烯酰胺凝胶电泳(SDS-PAGE)及双向电泳(2-DE)检测。结果表明:酚法最佳,所获蛋白在单向SDS-PAGE中形成条带数目多而清晰;经双向电泳分离用银染显色,可检测约548个蛋白点,图谱分辨率较好,蛋白点清晰,主要集中在等电点pH5~8、相对分子量25.0~70.0kD,可有效解析烟草根系的蛋白质组。 相似文献

In order to develop an efficient method about protein extraction which is suitable for apple proteomic analysis, four protocols of total protein extraction from apple leaves, which are trichloroacetic acid/acetone precipitation method (TCA), phenol extraction methanol/ammonium acetate precipitation method, Tris-HCl extraction method and modified Tris-HCl extraction method were compared. The results showed that the modified Tris-HCl extraction method was the most suitable method in protein extraction for two-dimensional electrophoresis (2-DE) from apple leaves based on the highest resolution and more informative spots of 2-DE gels with no apparent vertical or horizontal streaking. 相似文献
