贝叶斯联合模型与中国洞穴鱼类分化时间的估算(鲤科:金线鲃属) [PDF]

open access: yes, 2008
金线鲃属分布于中国云贵高原及周边地区,包括10多种适应于洞穴生活、具有不同程度眼睛和色素退化的典型洞穴鱼类.迄今为止,金线鲃属的系统发育关系还存在很大争议.我们获得了34种金线鲃属鱼类及外类群的细胞色素b和ND4基因序列,用贝叶斯联合模型分析数据,重建了金线鲃属的系统发育关系;并用松散分子钟估算了本属及内部分支的起源时间.金线鲃属的单系性得到强烈的支持,本属可分为6个分支.此外,本研究结果还支持洞穴物种的多系起源假说以及季氏金线鲃(Sinocyclocheilus jii)的基部位置 ...

Complete mitochondrial genome of the mud loach Misgurnus mizolepis (Cypriniformes, Cobitidae) and its phylogenetic position in the Cypriniformes

open access: yesMitochondrial DNA Part B, 2016
The mud loach (Misgurnus mizolepis) is a small benthic species belonging to the family Cobitidae. In this study, I report the first sequencing and assembly of the complete mitochondrial genome of M. mizolepis. The complete mitochondrial genome is 16,647 bp long, consisting of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region ...
