International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Integrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

The Genome of Phoebe zhennan (Lauraceae) and Comparative Genomics of Phoebe 楠木(樟科)基因组与楠属植物比较基因组学研究
Integrative Conservation, Volume 4, Issue 4, Page 584-599, December 2025.Phoebe zhennan is a Chinese endemic and valuable timber species of Phoebe (Lauraceae). We present a chromosome‐level genome assembly of P. zhennan. Our research provides novel insights into the genome evolution of Phoebe, including whole‐genome duplication, phylogenetic relationships of magnoliids, and key MYB regulatory genes involved in lignin ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

, 2008 为了研究重要功能基因在多倍体基因组中的演化情况,通过分子克隆的方法从四倍体大鳞结鱼(Tordouronensis)中获得13条Sox基因序列,分别为SoxB,SoxC和SoxE组成员.对大鳞结鱼Sox基因系统进化分析的结果支持鱼类特异的基因组重复的假说,同时表明,基因Sox19可能为真骨鱼特有的Sox基因家族成员.序列分析显示,与其他物种相比大鳞结鱼中Sox基因的碱基替代,绝大多数为同义替代.结果表明,所得到的Sox基因序列均受到净化选择,同时由多倍化所造成的重复基因对Sox4a ...
