摘要
Abstract
It was assumed that closely relative intestinal bacteria hadclosely relative intestinal hosts because of the same or similar symbiosis, vice versa. Based on this assumption, the amount of intestinal bacteria detected in intestines of Cyprinidae fishes was used to analyze the phylogenetic relationship among 8 Cyprinidae fishes: Ctenopharyngodon idellus, Mylopharyngodon piceus, Hypophthalmichthys molitrix, Aristichthys nobilis, Cyprinus carpio haematopterus, Carssius auratus, Megalobrama amblycephala and Megalopbrama terminalis. In the phylogenetic trees, using NJ and UPGMA methods,the genera of each subfamily were joined to a comnon nodal point. Between the subfamilies, Leuciscinae and Culterinae were first joined to a nodal point. The point, which Hypophthalmichthinae and Cyprininae were together joined to, was their ancestral nodal point. The sequence data of the 2 genes cytochrome b and ND4 of mitochondrial genome were also used to analyze the phylogenetic relationship between the 5 subfamilies of Cyprinidae. Both of the phylogenetic trees of cytochrome b and ND4 built by NJ method were different from each other in topological structure. Nevertheless, a common conclusion inferred from the 3 phylogenetic trees is that Cyprinidae is the most primary group and monophyletic in the 5 subfamilies, whereas C.auratus may be the most primary lineage; Culterinae has no position in Cyprinidae phylogenetic tree.关键词
