The cloning, functional Analysis and identification of SNPs associated with growth traits of three digestive enzymes in Haliotis diversicolor [PDF]
, 2016 杂色鲍（Haliotisdiversicolor）是我国南方的养殖鲍种，具有重要的经济价值。研究与杂色鲍生长相关的基因及其表达规律，并筛查与生长性状相关联的SNP位点，对于深入了解生长性状调控的分子机制，培育具有优良性状的新品种具有重要意义。鲍鱼是植食性软体动物，以海藻为主要的食物和能量来源，而鲍鱼消化液中比较突出的多糖降解酶是褐藻胶裂解酶、纤维素酶、甘露聚糖酶β-1，3-葡聚糖酶和淀粉酶。因此本研究将褐藻胶裂解酶、纤维素酶和淀粉酶的三个基因作为杂色鲍生长性状相关的候选基因，通过基因克隆、饵料对酶活影响、

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 ...

Toxicity of BaP exposure during embryonic stage in zebrafish: the mechanisms involved [PDF]
, 2016 多环芳烃（PolycyclicAromaticHydrocarbon，PAH）是环境中一类分布广泛的持久性有机污染物。苯并（a）芘（Benzo(a)pyrene，BaP）作为代表性的PAH具有包括神经毒性和生殖毒性在内的多种毒性。截至目前，关于BaP神经毒性的研究大多集中于高浓度或短期的暴露实验，而环境水平浓度下、长期的BaP暴露是否能引起同样的神经毒性则研究得较少；此外，胚胎时期低浓度BaP暴露对成年阶段的神经毒性、生殖毒性效应及其机制研究更为少见。因此本研究以斑马鱼为模式动物，分别进行环境水平浓度 ...

Integrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

Jixie chuandong, 2015 针对现有测量方法存在的问题,基于测量状态与加工状态一致的检测原理,设计了环面蜗杆精度测量原理。通过设置自动标定程序和高精密时栅转台使系统自动建立三维空间的测量坐标系,并利用坐标旋转法测得测头的回转半径。采用随动控制方式来测量环面蜗杆各齿面的点在测量坐标系中的坐标值,从而得到环面蜗杆的精度。系统采用金字塔式的结构使系统更稳定、可靠性强。通过实验,验证了本方案的可行性,测得环面蜗杆螺旋线的误差为±4μm。对系统进行等精度重复性实验,系统的极差为0.9μm,方差分析说明各测量点的误差值无显著差异。

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...
