中国斑腿蝗科线粒体基因的分子系统学研究(英文)

使用线粒体基因COⅠ,COⅡ,Cytb分析并建立中国斑腿蝗科部分种属的系统发育关系,其中对7个新种(Apalacris eminifronta,Caryanda pseudodentata,Caryanda bannaensis,Caryanda ruiliensis,Longchuanacris fui,Longchuanacris xiaoheis-hanensis,Podismodes dabieshanensis)的归属从分子角度也做了讨论。本研究将实验所获得的56条序列与NCBI中所收录的斑腿蝗科序列进行联合分析,采用最大似然法、贝叶斯推论等系统分析方法并综合P距离进行分析,最终得出以下几点结论:①龙川蝗属Longchuanaceis Zheng et Fu划归卵翅蝗亚科Caryandinae;②蹦蝗属Sinopodisma Chang、云秃蝗属Yunnanacris Chang均为华秃蝗属Podismodes Ramme的同物异名;③不支持Storozhenko将豫蝗属Yupodisma Zhang et Xia并入安秃蝗属AnapodismaDovnar-Zapolskii,从本研究所建的系统发育树来看,豫蝗属仍应作为秃蝗亚科Podisminae的一个独立属;④前人利用形态特征鉴定的七个新种与分子系统发育分析结果一致,新种独立有效。

Phylogeny of the Chinese Cantatopidae (Orthopter: Acridoidea) Inferred from Mitochondrial DNA Sequences

DNA sequence comparisons of the mitochondrial COI, COII, and Cytb genes were used to infer phylogenetic relationships of partial genera and species of Cantatopidae, including 7 new species (Apalacris eminifronta, Caryanda pseudodentata, Caryanda bannaensis, Caryanda ruiliensis, Longchuanacris fui, Longchuanacris xiaoheishanensis, Podismodes dabieshanensis). Phylogenetic trees were constructed using maximum likelihood and Bayesian inference. The combined results suggest several phylogenetic relationships including: ① Longchuanacris is placed within the subfamily Caryandinae;② Sinopodisma and Yunnanacris are both synonyms of Podismodes;③ Yupodisma is still a separate genus within Podisminae instead of a synonym of Anapodisma;4)the molecular phylogeny of 7 new species is consistant with previous morphological phylogeny. This finding suggests a combination of molecular and morphological approaches are necessary for accurate species identification.
