Deep-sowing is an important method for avoiding drought stress in crop species,including *** candidate genes is the groundwork for investigating the molecular mechanism underlying maize deep-sowing *** study evaluated four traits(mesocotyl length at 10 and 20 cm planting depths and seedling emergence rate on days 6 and 12)related to deep-sowing tolerance using a large maize population containing 386 inbred lines genotyped with 0.5 million high-quality single nucleotide polymorphisms(SNPs).The genomewide association study detected that 273 SNPs were in linkage disequilibrium(LD)with the genetic basis of maize deep-sowing *** RNA-sequencing analysis identified 1944 and 2098 differentially expressed genes(DEGs)in two comparisons,which shared 281 *** comparing the genomic locations of the 273 SNPs with those of the 281 DEGs,we identified seven candidate genes,of which GRMZM2G119769 encoded a sucrose non-fermenting 1 kinase interactor-like ***2G119769 was selected as the candidate gene because its homologs in other plants were related to organ length,auxin,or light *** gene association mapping revealed that natural variations in GRMZM2G119769 were related to phenotypic variations in maize mesocotyl *** expression of GRMZM2G119769 was higher in deep-sowing tolerant inbred *** results suggest that GRMZM2G119769 is the most likely candidate *** study provides information on the deep-sowing tolerance of maize germplasms and identifies candidate genes,which would be useful for further research on maize deep-sowing tolerance.

　　A novel 5-deoxyflavone compound, 7, 8-dimethoxy-3′, 4′-methylene-dioxyflavone (1), was in 2002 isolated from the root bark of Albizia Odoratissima. [1] The compound 1 was preparaed from pyrogallic acid (2) and piperonal(5) in four steps (Scheme 1). [2] The spectroscopic data (1H NMR, 13C NMR, MS and IR) of 1 were in good agreement with those of natural product. [ 1]……

The local structure and thermophysical behavior of Mg-La liquid alloys were in-depth understood using deep potential molecular dynamic(DPMD) simulation driven via machine learning to promote the development of Mg-La alloys. The robustness of the trained deep potential(DP) model was thoroughly evaluated through several aspects, including root-mean-square errors(RMSEs), energy and force data, and structural information comparison results;the results indicate the carefully trained DP model is reliable. The component and temperature dependence of the local structure in the Mg-La liquid alloy was analyzed. The effect of Mg content in the system on the first coordination shell of the atomic pairs is the same as that of temperature. The pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the Mg-La liquid alloy, which is particularly pronounced in the 80at% Mg system and disappears at elevated temperatures. The density, self-diffusion coefficient, and shear viscosity for the Mg-La liquid alloy were predicted via DPMD simulation, the evolution patterns with Mg content and temperature were subsequently discussed, and a database was established accordingly. Finally, the mixing enthalpy and elemental activity of the Mg-La liquid alloy at 1200 K were reliably evaluated,which provides new guidance for related studies.

随着智能信息技术的发展,知识图谱已被广泛应用于智能搜索等各个领域。知识图谱中的信息一般采取RDF(S)的数据模型来表示。知识图谱的构建需要从大量的数据源抽取信息,而数据库是不可忽视的重要数据源。近几年,对象关系数据库得到了广泛的应用,且其中存储着丰富的语义信息,而基于对象关系数据库自动构建RDF(S)的研究却较少。因此,文中给出了对象关系数据库与RDF(S)的形式化定义,根据形式化定义将对象关系数据库中的语义信息进行抽取,提出了构建RDF(S)数据的映射规则。该映射规则不仅考虑了数据库的面向对象的语义,还考虑了数据库的约束,可以充分抽取数据库中包含的语义信息。最后实现了一个名为ORDB2RDF的映射工具,验证了该映射规则的正确性与映射结果的语义完整性。
