Application of DNA molecular markers in endangered species conservation

Chen Xia

Abstract

With the development of techniques in molecular biology,many high-efficient and reliable DNA molecular markers came forth in succession in past twenty years.In this paper,the basic principals and technical characteristics of restricted fragment length polymorphism(RFLP),microsatellites polymorphism/simple sequence repeat(SSR),random amplified polymorphic DNA(RAPD),and amplified fragment length polymorphism(AFLP)were summarized,and the application of DNA molecular markers in conservation biology,e.g.,in the studies of population genetics of endangered species,factors causing danger,and conservation strategies,was also introduced.
