我国检疫性有害生物DNA条形码信息系统建设

DNA barcode databases on Chinese quarantine pests.

DNA条形码是利用一个或几个DNA片段进行物种鉴定的新技术,一经提出,就成为生物学领域的研究热点之一。在科技部的资助下,启动了国家科技支撑计划"检疫性有害生物DNA条形码数据库建设及应用"。旨在建设我国检疫性有害生物DNA条形码信息系统,建立检疫性有害生物DNA条形码数据库、凭证标本库及数字标本库,搭建我国检疫性有害生物DNA条形码鉴定平台。本文在简要回顾了国际、国内开展条形码技术与信息系统建设研究进展的基础上,提出高质量的条形码数据及高效的DNA条形码数据信息系统,是生命条形码信息系统建设的核心内容,并从DNA条形码数据的质控与信息系统建设架构方面,对我国检疫性有害生物DNA条形码信息系统建设提出了一些具体建议。

Short DNA sequences from a standardized region of the genome provide a DNA barcode for identifying species. The construction of DNA barcode databases on Chinese quarantine pests was supported by grants from Ministry of Science and Technology of the People＇s Republic of China. It is a repository for the specimen and sequence records that form the basic data unit of all barcode studies. It is a workbench that aids the management, quality assurance and analysis of barcode data. When fully developed, this database will provide a reliable, costeffective and accessible solution to Chinese quarantine pests.
