苹果叶片总蛋白提取及其双向电泳分析 总被引:1,自引:0,他引:1
蛋白质提取方法和电泳条件的建立是蛋白质组学研究中双向电泳分析的关键。通过比较不同提取方法,包括酚/SDS抽提、TCA-丙酮沉淀法、甲醇/醋酸铵沉淀法以及改良HB-酚抽提方法。此外,还优化了样品上样量、等电聚焦程序设置等条件。从所得2-D图谱分离效果来看,改良HB-酚抽提方法所得蛋白点数最多,2-D图谱背景清晰、分离效果好,明显优于其他3种方法。300μg上样量可作为苹果叶片总蛋白2-DE分析的理想的上样量,同时优化了等电聚焦程序,最终得到的2-D图谱分离效果较为理想。该研究的开展也为苹果叶片蛋白质组学后续研究奠定了基础。 相似文献

Cities in China support higher human population densities compared to those in western countries; consequently, the high pressure placed on cultural ecosystem services (CES) provision of residential green spaces might hinder overall human wellbeing and the maintenance of avian diversity. Thus, this study aimed to identify how to meet the main preferences of citizens for residential green spaces while simultaneously enhancing bird diversity in city neighborhoods, generating a win-win scenario for human needs and biodiversity. This study was implemented using 568 questionnaires for residents and GLMM for bird-environment statistical analyses. Residents in Beijing preferred higher levels of bird species richness than individual abundance in neighborhoods. Residential green space appeared to serve as the movement corridor for some rare species, indicating the importance of promoting the presence of migrant bird guilds, which is currently incidental. The cultivation of fruit-bearing shrubby plants was supported by most city residents, and would also promote the presence of migratory birds in green spaces. In contrast, while increasing the width of residential green spaces would benefit migratory birds, it had less public support. This multi-disciplinary study clearly demonstrated that both the quality of life of humans in cities and biodiversity conservation could be efficiently incorporated in green space plans, even under highly urbanized circumstances. 相似文献

Summary The shoot fly, Atherigona soccata is an important pest of sorghum, and host plant resistance is one of the most effective components for managing this pest.
Most of the hybrids grown in India based on milo cytoplasm (A1 cytoplasm) are highly susceptible to shoot fly. Therefore, the present studies were undertaken to evaluate different male-sterile
cytoplasms (CMS) for their relative susceptibility to sorghum shoot fly. Oviposition and deadheart formation were significantly
lower on the maintainer lines as compared to the corresponding male-sterile lines. Among the cytoplasms tested, A4M cytoplasm showed antixenosis for oviposition and suffered lower deadheart formation than the other cytoplasms tested. The
A4G1 and A4M cytoplasms suffered lower deadhearts in tillers than the other cytoplasms. Recovery following shoot fly damage in A4M, A3, and A2 cytoplasms was better than in the other cytoplasms tested. The larval and pupal periods were longer and male and female pupal
weights lower in A4M and A4VzM CMS backgrounds compared to the other CMS systems. Fecundity and antibiosis indices on CMS lines were lower than on the
B-lines. The A4M cytoplasm was found to be relatively resistant to sorghum shoot fly, and can be exploited for developing shoot fly-resistant
hybrids for sustainable crop production in future. 相似文献
