中文摘要:
      测定了内蒙古11种主要草原蝗虫的线粒体基因组16S rDNA序列,并构建了其分子系统树。在获得的505 pb序列中,G+C占302%,A+T占698%,表现出A/T偏向性。在505 bp个碱基中检测到156个多态性位点,占碱基总数的309%。156个多态性位点中包括50个单变异多态性位点(占总位点数的321%)和106个简约信息位点(占总位点数的679%)。分别采用NJ、ME、MP和UPGMA聚类方法构建系统发生树。结果表明,4科的17种蝗虫共聚为6支,其中槌角蝗科、斑腿蝗科与网翅蝗科3个科的蝗虫先聚在一起,再与斑翅蝗科相聚。4种聚类方法中UPGMA聚类法更为符合传统的以形态学为基础的分类体系。
英文摘要:
      The 16S rDNA sequences of 11 important grasshopper species distributed in Inner Mongolia grassland were analyzed In the 505 bp fragment of mitochondial 16S rDNA, G+C was 302% and A+T was 698%, showing a tendency to A/T 156 polymorphic loci were detected in 505 bp base, accounting for 309% of the total number of bases, including 50 single variation polymorphic sites and 106 parsimony informative sites The molecular phylogenetic trees were constructed by NJ, ME, MP and UPGMA, respectively The results showed that 17 grasshopper species from 4 families were clustered into 6 groups Gomphoceridae, Catantopidae and Arcypteridae were firstly clustered and then clustered with Oedipodidae Among four clustering methods, UPGMA result was consilient to the classification scheme of Acrioidea based on morphology.
