Patent number: 10306073Abstract: A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.Type: GrantFiled: March 2, 2015Date of Patent: May 28, 2019Assignee: Huawei Technologies Co., LtdInventors: Weihua Qiao, Xinfa Wang, Cheng Chen, Shiyong Tan, Yan Li, Shibi Huang, Peng Zhao, Yuxin Mao

Publication number: 20110072538Abstract: The use of a lignin monomer synthetic gene 4-CL encoding 4-coumarate: CoA ligase from Populus tomentosa in increasing Sclerotinia resistance and lodging resistance. The 4-CL gene is responsible for catalyzing various cinnamic acids and their derivatives to produce respective coenzyme A esters, involved in the synthesis of various downstream secondary products, and is the key gene in the regulation of lignin synthesis. Results of the study show that, increase of lignin content improves plant's resistance against pathogenic infection, enhances the stem strength of rape, and thus significantly improves the lodging resistance. Specifically, the result shows that lignin content of transgenic rape increases more than 10% compared to lignin content of recipient control; lesion extension area of transgenic plant leaves decreases around 30% compared to recipient control; and stem strength of transgenic plant increases up to around 20% compared to control.Type: ApplicationFiled: November 25, 2008Publication date: March 24, 2011Applicant: Oil Crops Research Institute Chinese Academy of Agricultural SciencesInventors: Hanzhong Wang, Xiangdong Yang, Guihua Liu, Xinfa Wang, Wei Hua, Jing Liu, Qing Yang, Yuanben Zheng
