[Objectives]To explore the evolution of the legal system of farmland protection and explore the rules and characteristics of policy development based on the theory and logic of institutional change since China's reform and opening up,reveal the problems and deep-seated reasons of its legislation,clarify the direction of farmland protection in the new period,and solve the"non-agricultural""non-grain"and ecological problems of farmland.[Methods]Literature analysis and inductive deduction methods were used.[Results]The evolution of the farmland protection legal system has gone through the process of"national consciousness-policy guidelines-institutional system",the change from"single subject to multiple subjects";change from the use of"one-way administrative means to coordinated use of administrative,economic and technical means".The practical problems of the farmland protection legal system are mainly due to the insufficient systematization of the farmland protection legal system itself,the generalization of quantity protection,the transformation of quality protection,and the absence of ecological protection.[Conclusions]It is recommended to improve the existing farmland protection legal system from the establishment of the Farmland Protection Law,the improvement of the farmland protection public participation mechanism and supervision mechanism,the establishment of the farmland quality construction and improvement system,the differentiated farmland occupation and supplementation balance system,and the ecological restoration system.

第三届全国植物开花·衰老与采后生物学大会

RNA editing plays a key post-transcriptional role in gene expression. Existing studies on cytidine-to-uridine RNA editing in plants have focused on maize, rice, and ***, the importance and regulation of RNA editing in several critical agronomic processes are not well understood, a notable example of which is fruit ripening. Here, we analyzed the expression profile of 33 RNA editing factors and identified 11 putative tomato fruit ripening-related factors. Knocking-out SlORRM4 using genome editing strategy delayed tomato fruit ripening with lowering respiratory rate and ethylene production. Moreover, our combined nRIP-seq and RNA editing extent analysis classified 19 direct SlORRM4 target coding genes that physically bound to SlORRM4 and were with large variation of RNA editing extent between WT and slorrm4. Inspection of SlORRM4 targets function suggested that SlORRM4 participates in the regulation of mitochondrial respiratory and ribosome function. Therefore, knock-out of SlORRM4 impaired tomato fruit respiratory, resulting in large initiation delay of the fruit ripening. Large-scale analysis of IP-MS revealed that SlRIP1 b, another critical RNA editing factor, interacted with SlORRM4 in the editosome complex. In conclusion, our study reveals that SlRIP1 b-containing SlORRM4 editosome complex globally regulates C-to-U RNA editing in mitochondria, which fine-tunes SlORRM4 target genes function resulting in mitochondrial respiratory dysfunction and a corresponding delay on initiation of tomato fruit ripening. Our findings provide new insights into understanding comprehensive atlas of RNA editing factor function and the diverse regulatory mechanisms of fruit ripening.

水、能源、粮食存在互相依赖的纽带关系,黄河流域作为三者矛盾突出且集中的典型区域,实现水-能源-粮食纽带关系协同演化,是保障流域资源安全、维护生态平衡、实现可持续发展的重要前提。基于协同学原理,按照序参量-子系统-复合系统的逻辑,从流域层和区域层,对2010—2019年黄河流域的水-能源-粮食纽带关系协同演化进行实证分析及ARIMA预测。结果发现:①从全流域看,3个子系统有序度演化近10年来均有上升,但三者间纽带关系演化长期处于低协同状态,其中,水-粮食协同度略高于能源-粮食协同度和水-能源协同度;②分区域看,上游和下游各子系统有序度演化近10年来升降各异,而中游各子系统有序度演化不断上升,3个区域中水-能源-粮食纽带关系演化均长期处于低协同状态;③根据ARIMA预测,纽带关系短期仍处于低协同状态,水资源相对于能源和粮食仍是首要约束。最后,从流域层提出“以水为刚性约束,多要素互动”,从区域层提出“生态位错位发展,多区域协同”等政策启示。

作为植物体内一类重要的信号分子,小肽在飞摩尔(fmol)级的浓度下被相应的细胞质膜类受体激酶识别并结合,开启小肽-受体介导的细胞间信号转导过程,从而调控植物干细胞的生长与增殖,调节根、茎、叶、花和果实等多种植物器官的发育,协调植物响应生物和非生物胁迫等多种生理过程。随着研究的不断深入,越来越多的报道揭示了小肽在水稻(Oryza sativa)、玉米(Zea mays)、马铃薯(Solanum tuberosum)及番茄(Solanum lycopersicum)等多种作物农艺性状中的重要调控功能,暗示着小肽信号在作物遗传改良中的巨大应用潜力。本文系统总结了小肽-受体介导的信号转导模式在植物中的生物学功能及分子机制,重点综述了小肽在调控作物产量、品质和抗性等重要农艺性状中的研究进展,并讨论了小肽信号应用于作物育种改良的策略,最后提出了小肽研究的未来方向。
