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 ...

黑鹳是重要的濒危物种,在我国动物园中已经建立了稳定的人工饲养种群,成为这一个物种的活体基因库。当前,该种群需要开展精准的遗传管理,微卫星是达到精准管理的重要遗传标记,但是,黑鹳的微卫星位点尚未有报道。本研究从白鹳、东方白鹳、林鹳和大蓝鹭4个物种中,选择29个扩增效果较好、具有多态性的微卫星位点,通过交叉扩增,测试在黑鹳的可用性。结果显示,共有18个位点能够成功扩增,其中1个位点(Cc01)分型困难,10个位点(Cc05、Cc06、WSμ13、WSμ14、Cbo102、Cbo121、Cbo133 ...

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 ...

组蛋白化学修饰与12/15-脂氧化酶代谢途径在糖尿病肾病发展中的作用
糖尿病肾病(DKD)是糖尿病患者最常见的微血管并发症之一,也是终末期肾衰竭的主要原因,其发病机制比较复杂。大量实验证实表观遗传学机制包括组蛋白化学修饰与脂质代谢产物12/15脂氧化酶(12/15-LO)参与调控DKD的特征性病理生理过程,本综述将从他们之间的相互作用关系出发,进一步探讨DKD发病机制,为DKD的治疗提供新的研究方向。

Qilianshan National Park covers approximately 40% of core snow leopard habitat patches and 50% of movement corridors between patches. Including more of these important areas within the park boundaries should be considered, as the Qilianshan National Park sits at a pivotal juncture between critical snow leopard habitat in China and Mongolia, and may ...

Assessing the genetic diversity of edible insects harvested from the wild is a pre‐requisite for designing conservation and management policies. The caterpillars of Gynanisa maja (Saturniidae) are harvested in large numbers in mopane woodlands in southern Africa, where they represent a seasonal source of income and nutrition to many rural communities ...
