大头鲤原种种群的遗传现状 [PDF]

open access: yes, 2012
大头鲤(Cyprinus pellegrini)是一种云南高原湖泊特有的国家Ⅱ级重点保护鱼类。土著种大头鲤与外来种鲤(C.carpio)的渐渗杂交在星云湖野生种群中已经广泛发生。本研究结合形态和微卫星及线粒体DNA分析检测了螺蛳铺大头鲤原种种群的遗传现状。结果显示,螺蛳铺大头鲤样本所有个体在形态上位于大头鲤与鲤的参照样本之间;在微卫星因子对应分析中也显示,其位于大头鲤与鲤的参照样本之间,但与大头鲤参照样本较为相似;在线粒体DNA分析中显示,都具有鲤的单倍型 ...

Phylogenomic insights into the relationship and the evolutionary history of planthoppers (Insecta: Hemiptera: Fulgoromorpha) 基于基因组的系统发育分析为蜡蝉亚目(Fulgoromorpha)的系统发育关系及进化提供新见解

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 495-518, July 2025.
Using genomic data from 285 species across 19 planthopper families, we conducted the first phylogenomic study targeting global planthoppers and inferred their phylogeny with the highest resolution so far. We proposed taxonomic changes including the establishment of a new family Borysthenidae stat. rev. and a new superfamily Meenoploidea superfam.

Studies on complete mitochondrial genome and population genetics of Larimichthys polyactis (Bleeker 1877) [PDF]

open access: yes, 2009
小黄鱼Larimichthyspolyactis(Bleeker1877)为广泛分布于渤海、黄海和东海的暖温性底层鱼类,是中、韩、日三国的重要的海洋渔业经济种类。由于过度捕捞和渔业生态环境污染,小黄鱼的资源受到严重破坏,种群结构趋向简单。本研究以渤海、黄海和东海的小黄鱼为研究对象,采用线粒体DNA(MitochondrialDNA,mtDNA)序列分析和微卫星DNA标记对其线粒体基因组全序列和群体遗传学进行了研究,阐明小黄鱼的起源与进化、系统地理格局、群体遗传结构和种群组成 ...

Molecular systematics and genetics diversity of two lancelets in China Seas [PDF]

open access: yes, 2009
文昌鱼由于其独特的系统进化地位,而被广泛用作研究分子进化、胚胎发育和脊椎动物起源的关键模式生物。从分子水平开展对文昌鱼的研究大多集中在基因/基因家族的演化等方面,对该类动物的起源进化、系统发育和遗传多样性的研究还远远不够深入。 在本研究中,我们测定了厦门分布的日本文昌鱼线粒体基因组全序列,结合本实验室先前测得的白氏文昌鱼mtDNA全序列,与已报道的来自日本和中国其它海区的样本数据进行了比较,进一步确证厦门海域的鳃口文昌鱼属有2个独立的物种 ...
