Abstract: The construction of a genomic library is essential to research on genome structure and function. A comprehensive genomic library makes it possible to screen and isolate any DNA fragments from it. With the emergence of various vector systems in recent years, genomic libraries have also developed. Among these vector systems, the bacterial artificial chromosome (BAC) is presently the most widely used due to its higher transformation efficiency, lower chimerism level, ease with which inserted fragments can be isolated, and larger capability. Because of increasing human population, environmental destruction, and the rapid development of molecular genetics in recent decades, the newfield of conservation genetics, employing the theories of conservation biology and molecular genetics, has come on the stage. The construction of a genomic library of endangered wildlife, which has been playing a more and more important role in species conservation strategy, is the most effective means to save the genome resource and to provide material support for advanced research in conservation genetics.
