title: [Molecular phylogenetic relationships among species in Oxya serville(Orthoptera: Catantopidae) based on random amplified polymorphic DNA(RAPD)].
abstract: The molecular phylogenetic relationships of five species of Oxya Audient-serville including O. chinensis, O. brachyptera, O. agavisa, O. japonica and O. intricata were studied with RAPD. Genomic DNA of forty-one individuals were amplified with eight oligonucleotide (10 mer) primers which were previously selected, the specifical bands occured in all them, a total of 96 clear and reproducible bands (rang from 200-2500 bp) were generated, 95 of which were polymorphic band, the only one band (850 bp) which was amplified with S362 was common to five species of Oxya. The obtaining segments of individual primer were between 8-16, the average was 12. A molecular phylogenetic tree based on was constructed Euclidean distance among five species of rice grasshopper by between-groups linkage method, the result indicated O. chinensis was closely related to O. brachyptera, the genetic relationship of O. japonica and O. agavisa was also close, whereas O. intricata had far phylogenetic relationship with them. The results of dendrogram were consistent with the previous conclusion of morphologic classification and cytotaxonomy, and suggested RAPD was suitable for analysis of phylogenetic relationships among species of Oxya.
