党中央、国务院高度重视农田水利和高标准农田建设.习近平总书记多次作出重要指示,强调要加快推进高标准农田建设,切实提高建设标准和质量,真正实现旱涝保收、高产稳产.rn11月4日,全国冬春农田水利暨高标准农田建设电视电话会议在京召开.中共中央政治局常委、国务院总理李克强作出重要批示,要求抓住今冬明春时机,扎实推进农田水利和高标准农田建设,确保建设标准和质量,完成好各项建设任务,为保障粮食和重要农产品有效供给、全面推进乡村振兴和农业高质量发展提供坚实支撑.

2021年是“十四五”开局之年,也是全面推进乡村振兴的关键之年.《中国农业综合开发》杂志作为全国唯一专职服务农田建设系统的期刊,坚持以习近平新时代中国特色社会主义思想为指导,紧紧围绕三农工作大局和农田建设中心工作,深入贯彻实施藏粮于地、藏粮于技战略,以推动农田建设高质量发展为主线,发布政策法规制度,解读热点难点问题,展示交流典型经验,示范推广先进模式,唱响了农田建设和耕地质量保护的主旋律,推动农田建设工作迈上新台阶,为保障国家粮食安全、促进乡村振兴、助力农民增收发挥了积极作用.
Poly(ADP-ribosyl)ation (PARylation) is a posttranslational modification reversibly catalyzed by poly(ADP-ribose) polymerases (PARPs) and poly(ADP-ribose) glycohydrolases (PARGs) and plays a key role in multi-ple cellular processes.The molecular mechanisms
Paraquat is one of the most widely used nonselective herbicides and has elicited the emergence of para-quat-resistant weeds.However,the molecular mechanisms of paraquat resistance are not completely un-derstood.Here we report the Arabidopsis gain-of-funct
