DNA条形码基于较短的DNA序列实现物种的快速、准确鉴定,不仅加快了全球生物物种的鉴定和分类步伐,也为生物多样性的管理、保护和可持续利用提供了新思路和研究方法。植物DNA条形码标准数据库的不断完善,将使植物多样性信息的快速获取成为可能;将不同类型数据资源整合、共享和利用,构建植物DNA条形码数据共享平台,是满足公众对物种准确鉴定和快速认知的重要支撑。本文介绍了近年来植物DNA条形码的研究进展;植物DNA条形码参考数据库的研发现状和存在的问题。结合上述问题,围绕"大数据"时代背景,对如何管理和使用好海量的植物信息,如何构建数据共享平台提出了一些设想:(1)数据共享平台的元数据应尽可能翔实、丰富、准确和多关联;(2)数据标准应统一规范;(3)查询入口方便、迅速、多样,易于管理,便于实现更大程度的数据共享和全球化的合作交流。
DNA barcoding technology provides an opportunity for rapid,accurate,and standardized species-level identification using short DNA sequences.This method speeds up species identification and classification,and presents a new tool for the management,conservation and sustainable development of biodiversity at a global level.Due to improvements in plant barcode database availability and functionality,it is becoming feasible to meet increasing demands for biodiversity information.A framework is needed for a barcoding server platform that utilizes,integrates,and s hares among different data types.Such a platform would be an important step towards enabling the public to rapidly identify species and acquire species-related digital information.In this paper,we review current progress on plant DNA barcoding.Secondly,we summarize the current status of,and identify bottlenecks for,plant DNA barcode reference libraries specifically.Thirdly,in the Big Data era,it is indispensable to manage and make good use of massive amounts of plant information.We provide the following suggestions for the framework of server platform:(1) metadata should be substantial,accurate and correlative;(2) data should be norm alized;(3) query entrance is c onvenient,efficient,easy to manage,and available for l arge-scale data sharing and global communication.
