Poly(ester amide)s(PEAs)attract much attention as a new kind of biodegradable ***,the synthesis of PEAs with sequence-regulated chain structures is still complicated due to the multistep polymerization,high monomer purity,as well as the usage of organic solvents,which greatly inhibits its development and ***,a one-pot strategy without solvent was developed to synthesize the alternating PEA fromα,ω-amino alcohol and dicarboxylic acid by sequential polycondensation,where water was used as the controlling agent for amidation and ***,the amidation and esterification were controlled to proceed in turn by adding or removing water,realizing the one-pot preparation of alternating *** resultant PEA is characterized by^1H-and^(13)C-NMR,and its chain structure is confirmed to be highly quasi-alternating similar to alternating PEAs prepared by classical methods The evaluations from DSC and DMA demonstrate that the properties of quasi-alternating PEA(T_(m)=102℃,ΔH_(m)=30J·g^(-1))are far superior to those of random PEA(T_(m)=72℃,ΔH_(m)<1 J·g^(-1)).

Provenance of Upper Jurassic in North Yellow Sea Basin， Eastern North China Craton

引用

Journal of Earth Science 2024年

作者： Haitian Yu Zhongjie Xu Rihui cheng Duo wan Dan Gao Zhen Zhang College of Earth Sciences， Jilin University 2. Key Laboratory of mineral Resources Evaluation in Northeast Asia， ministry of Natural Resources College of Palaeontology， Shenyang Normal University Guangzhou Marine Geological Survey

Base on the detrital zircon U-Pb dating data， this paper discusses the provenance and constructs source-to-sink system of the Upper Jurassic in the North Yellow Sea Basin (NYSB)， Eastern North China Craton (ENCC). In addition， to avoid the bias of detrital zircon ages caused by variations in zircon fertility， we gather 1709 whole rock zirconium content values (ppm) from granitic rocks with different ages in the North China Craton (NCC). Base on mean Zr content of granitic rocks in each age， these granitic rocks can be divided into four groups: Group A consists of Jurassic， Group B consists of Paleozoic， Neo-Mesoproterozoic and Neoarchean， Group C consists of Early Cretaceous and Triassic， and Group D consists of Paleoproterozoic. This research assigns these groups zircon fertility factors (ZFF) of 1， 1.4， 1.8 and 2.2. The U-Pb age of detrital zircons from Late Jurassic sediments corrected by ZFF are statistically analyzed (K-S test， Similarity， Cross-correlation， Linkeness， Multidimensional scaling). And combining with palaeocurrent and palaeogeography， we construct two source-to-sink systems: 1) Jiaodong Uplift and Sulu Orogenic belt as the source area and the North Yellow Sea Basin as the sink area; 2) Liaodong Peninsula as the source area and the North Yellow Sea Basin as the sink area.

植物通过磷转运蛋白(phosphorus transporters, PHO)吸收和转运磷元素，磷元素作为植物生长发育必不可少的营养素之一，对作物产量、品质和抗逆性均有重要影响。高温是影响马铃薯(Solanum tuberosum)产量和品质的重要环境因子，为探究磷转运蛋白对马铃薯耐热性的影响，本研究通过农杆菌(Agrobacterium tumefaciens)介导法获得了过表达磷转运蛋白基因StPHO1.3的马铃薯转基因株系，比较转基因株系与野生型株系在高温(35℃)环境下的生长发育情况发现，过表达StPHO1.3能够增强马铃薯耐热性，对马铃薯生长发育具有促进作用。亚细胞定位结果显示，StPHO1.3在细胞膜上表达；通过酵母双杂交在膜系统文库质粒中筛选StPHO1.3的互作蛋白，并通过双分子荧光互补(bimolecular fluorescence complementation, BiFC)技术进一步验证，结果表明，StPHO1.3与光系统Ⅱ蛋白亚基和钙离子转运相关蛋白均有相互作用。综上所述，过表达StPHO1.3可能通过影响光合作用和信号转导，从而增强马铃薯抵御高温胁迫的能力，促进马铃薯生长发育。本研究为深入理解磷转运蛋白的功能提供了理论依据和参考。
