Electrocatalytic CO2reduction(ECR) coupled with organic oxidation is a promising strategy to produce high value-added chemicals and improve energy efficiency. However, achieving the efficient redox coupling reaction is still challenging due to the lack of suitable electrocatalysts. Herein, we designed two bifunctional polyimides-linked covalent organic frameworks(PI-COFs) through assembling phthalocyanine(Pc) and porphyrin(Por) by non-toxic hydrothermal methods in pure water to realize the above catalytic *** to the high conductivity and well-defined active sites with different chemical environments, Ni Pc-Ni Por COF performs efficient ECR coupled with methanol oxidation reaction(MOR)(Faradaic efficiency of CO(FECO) = 98.12%, partial current densities of CO(j CO) = 6.14 m A cm-2for ECR, FEHCOOH = 93.75%,j HCOOH = 5.81 m A cm-2for MOR at low cell voltage(2.1 V) and remarkable long-term stability).Furthermore, experimental evidences and density functional theory(DFT) calculations demonstrate that the ECR process mainly conducts on Ni Pc unit with the assistance of Ni Por, meanwhile, the MOR prefers Ni Por conjugating with Ni Pc. The two units of Ni Pc-Ni Por COF collaboratively promote the coupled oxidation-reduction reaction. For the first time, this work achieves the rational design of bifunctional COFs for coupled heterogeneous catalysis, which opens a new area for crystalline material catalysts.

Typically,conjugated polymers are composed of conjugated backbones and alkyl side *** this contribution,a cost-effective strategy of tailoring the length of alkyl side chain is utilized to design highperforming thieno[3,4-c]pyrrole-4,6-dione(TPD)-based large bandgap polymer donors PBDT-BiTPD(Cχ)(χ=48,52,56),in which x represents the alkyl side chain length in term of the total carbon number.A combination of light absorption,device,and morphology examinations make clear that the shorter alkyl side chains yield(i) higher crystallinity and more predominant face-on crystallite orientation in their neat and BHJ blend films,(ii) higher charge mobilities(6.7×10^(-4) cm~2 V^(-1) s^(-1) for C48 vs.3.2×10^(-4) cm~2 V^(-1) s^(-1) for C56),and negligible charge recombination,consequently,(iii) significantly improved fill-factor(FF) and short current(J_(SC)),while almost the same open circuit voltage(V_(OC)) of ca.0.82 V in their corresponding BHJ *** parallel,as alkyl side chain lengths decrease from C56 to C48,power conversion efficiencies(PCEs) increased from 7.8% for C56 to 11.1% for C52,and further to14.1% for C48 in their BHJ solar cells made with a narrow bandgap non-fullerene acceptor *** systematic study declares that shortening the side chain,if providing appropriate solubility in device solution processing solvents,is of essential significance for developing high-performing polymer donors and further improving device photovoltaic performance.

油菜是世界上重要的油料作物之一,然而土壤盐胁迫严重抑制油菜的生长发育和籽粒产量。前人研究表明,在盐胁迫下,植物通过表达一些miRNA,并调控其靶基因的表达,进而提高植物自身的盐胁迫抗性。本研究分别在200 mmol·L^(-1) NaCl处理(T)和对照(C)条件下培养油菜,取其地上部(S)和根(R)构建了12个小RNA文库进行高通量测序。通过对全基因组的miRNA进行差异表达分析,一共鉴定到了26个差异表达的miRNA,并预测了171个相应的靶基因。结合前期转录组的基因差异表达以及本研究的miRNA差异表达结果,推测miRNA156-SPL15-WRKY、miRNA397-LAC12-木质素、miR169-NFYA5和miR399-UBC29-泛素化等通路可能参与了油菜盐胁迫抗性调控。本研究所鉴定的miRNA及其核心靶基因丰富了油菜盐胁迫抗性的表观调控机制,并为油菜盐胁迫抗性的遗传改良提供了优异的基因资源。

脯氨酸积累是植物在生物和非生物胁迫下的一种重要的代谢适应性机制。吡咯啉-5-羧酸合成酶(P5CS)、吡咯啉-5-羧酸还原酶(P5CR)酶、脯氨酸脱氢酶(PDH)、吡咯啉-5-羧酸脱氢酶(P5CDH)是依赖谷氨酸的脯氨酸生物合成途径中的关键酶。油菜是世界上重要的油料作物,在油菜生长发育过程中,其时常遭受各类生物和非生物胁迫。然而迄今为止,在异源四倍体油菜中缺乏关于这些脯氨酸代谢基因家族的系统分析报道。本研究利用甘蓝型油菜‘中双11’基因组注释信息,分别鉴定到上述10个BnaP5CSs、6个BnaP5CRs、8个BnaPDHs以及3个BnaP5CDHs基因。这些基因家族在系统发育上分为不同的进化分支,同一亚组中的成员具有相似的理化特性、基因/蛋白质结构和保守的基序。进化压力分析表明,这些基因均遭受了强烈的纯化选择。启动子区的顺式作用元件分析揭示了油菜上述4类基因家族之间均存在共同的和特异的转录调控机制。本研究分别对‘中双11’油菜幼苗进行盐胁迫、低钾、低磷以及铵毒胁迫处理,分别取地上部及根部进行转录组测定与分析。结果显示,脯氨酸合成相关基因的表达水平在上述4种胁迫下普遍上调,而调控脯氨酸降解基因的表达水平则在盐胁迫和低磷胁迫情况下调;基因共表达分析显示BnaC4.P5CS1a、BnaA5.P5CS1等基因可能在脯氨酸介导的油菜逆境响应网络中发挥核心作用。本研究通过脯氨酸代谢基因家族的生物信息学鉴定以及多种非生物逆境下的转录特征分析,将为深入研究脯氨酸介导的逆境抗性提供理论依据,也将为脯氨酸介导油菜非生物胁迫抗性的遗传改良提供优异的基因资源。
