作者：陈昱洁浙江农林大学文法学院浙江杭州311300

建立健全生态产品价值实现机制,是贯彻落实习近平生态文明思想的重要举措,是践行绿水青山就是金山银山理念的关键路径。但是,作为森林生态产品供给主体的林农,其权益并未受到关注,林农主体资格、林农权利义务、政府职能定位等均缺乏明... 详细信息

建立健全生态产品价值实现机制,是贯彻落实习近平生态文明思想的重要举措,是践行绿水青山就是金山银山理念的关键路径。但是,作为森林生态产品供给主体的林农,其权益并未受到关注,林农主体资格、林农权利义务、政府职能定位等均缺乏明确的法律规定。鉴于此,以森林生态产品政府采购机制为切入口,分析生态产品本质属性、供给者获得和损害者赔偿原则、生态产品供给引导激励机制等方面存在的问题,建议确立林农供给主体的法定地位、明确林农的权利义务、调整政府的角色定位,以保护林农的生态产品权益,促进生态产品的持续、高效供给,推进生态文明法治建设。

为了探究水稻亲环素家族基因OsCYP22的功能,构建OsCYP22酵母双杂交诱饵载体,并利用水稻酵母双杂交cDNA文库筛选与OsCYP22相互作用蛋白。自激活试验结果表明,OsCYP22诱饵载体无自激活活性,也对酵母细胞无毒性。通过对酵母双杂交文库的筛选,共得到38个阳性菌落,结合测序结果和生物信息学的方法筛选到20个可能与OsCYP22相互作用的蛋白。进一步对OsCYP22分别与调控植物根系生长相关基因OsCSN5和OsRUB1的全长互作验证,结果显示OsCSN5与OsCYP22在酵母中相互作用。这为深入研究OsCYP22的生物学功能提供了理论依据。

Particle engineering has opened the floodgates to material science in both fundamental and application field. However, covalent interactions have not yet been adequately designed in the particle engineering for functional colloidal photonic crystals(CPCs). Herein, we achieved covalent coupling between carboxylrich poly(styrene-acrylic acid)(P(St-AA)) monodispersed colloidal particles and amine-rich carbon dots(CDs) based on an feasible and universal particle engineering strategy. The designed CDs-grafted P(St-AA)monodispersed colloidal particles initiate a hydrogen bond-driven assembly mode and ensure the construction of large-scale crack-free CPCs. Moreover, the CDs equipped with selective broad-band absorption capacity could improve the saturation of structural colors for high-visibility CPCs. Furthermore, an injectable photonic hydrogel(IPH) is developed to design CPC supraball hydrogel via integrating the CDsgrafted P(St-AA) CPC supraballs with supramolecular hydrogel. Combining superior flexibility, sufficient self-healing capacity of supramolecular hydrogel with visual optical information of our CPC supraballs, a cyclically reversible coding and decoding system was developed. Meanwhile, we firstly demonstrated the novel strategy of 3D supraballs-based passive cooling. The designed 3D CPC supraball hydrogel presents nearly full observation angle reflections behavior and excellent water evaporation capacity and achieves3.6 ℃ temperature drops, showing the application advantages in 3D thermal management. This work not only provides a new insight for manipulating optical properties of CPCs, but also demonstrates an easyto-perform platform, as well as indicates the direction for the promising application of CPCs.
