Regulatory Network of Serine/Arginine-Rich (SR) Proteins: The Molecular Mechanism and Physiological Function in Plants

Serine/arginine-rich (SR) proteins are a type of splicing factor. They play significant roles in constitutive and alternative pre-mRNA splicing, and are involved in post-splicing activities, such as mRNA nuclear export, nonsense-mediated mRNA decay, mRNA translation, and miRNA biogenesis. In plants, SR proteins function under a complex regulatory network by protein–protein and RNA–protein interactions between SR proteins, other splicing factors, other proteins, or even RNAs. The regulatory networks of SR proteins are complex—they are regulated by the SR proteins themselves, they are phosphorylated and dephosphorylated through interactions with kinase, and they participate in signal transduction pathways, whereby signaling cascades can link the splicing machinery to the exterior environment. In a complex network, SR proteins are involved in plant growth and development, signal transduction, responses to abiotic and biotic stresses, and metabolism. Here, I review the current status of research on plant SR proteins, construct a model of SR proteins function, and ask many questions about SR proteins in plants.     

绿色发展理念下的煤矿环保法律法规及其完善

为了在绿色发展的科学理念下完善我国煤矿环保立法,采用法规检索与文本分析研究法,集中梳理了与煤矿环保相关的法律法规,结果发现存在理念滞后、法多难治、忽视特殊性等不足之处。建议树立“绿色”的立法理念、制定专门的煤矿环保法及加强相应的地方立法。     

全数字化交流电机直接转矩控制系统

分析了直接转矩控制的基本原理。系统采用高低速均适用的磁链混合观测模型。提出一种改进的磁链和转矩控制器,同时给出了相应的电压矢量选择规则.还提出了开关频率自调整控制的思想。在此基础上,设计了8098单片机全数字控制系统,用它分别进行了数字仿真和实时控制,并给出实验结果。     

道路运输车辆燃料消耗量检测和监督管理办法解读

交通部依据先前制订的相关条例、法规,在今年6月审议通过的道路运输车辆燃料消耗量检测和监督管理办法,从控制营运车辆燃料消耗量入手,限制高耗能车辆进入道路运输市场,为实现节能减排总体目标提供了基础保障。对于提供相关动力并对整车厂生产的营运车辆能耗影响最大的柴油机生产企业来说,具有不可忽视的重要信息。解读‘‘方法”有助于提高产品燃油经济性的专项研究,做好节能降耗相关的技术准备工作,尽快提升和改进产品的燃油经济性和开发具有‘低油耗”的高竞争产品,从技术上支持整车生产企业的竞争力。
