新一代植物志iFlora是融人新一代测序技术、DNA条形码、地理信息和计算机信息技术等新元素的智能植物志或智能装备(李德铢等,2012)。由中国科学院昆明植物研究所发起的iFlora计划的阶段性目标是构建中国维管植物和重要大型真菌的开放、共享的数据平台,为我国生物多样性研究、保护和可持续利用提供重要的技术支撑,同时对宣传和普及植物科学知识、提高公众对生物多样性的认知等方面将发挥重要作用。在国家科技部科技基础性工作专项重点项目(2013FY112600)和国家高技术研究发展计划(863计划,2012AA021801)的支持下,结合中国科学院昆明植物研究所“一三五”任务的实施,项目组依托国家重大科学工程中国西南野生生物种质资源库、中国科学院生物多样性和生物地理学重点实验室(标本馆)和科技信息中心,构建完成了 iFlora的一个重要共享平台——“国家重点保护野生植物鉴定信息平台”。(相关链接见http://www.iflora.cn/)。 |

The first batch of China’ s Catalogue of the National Protected Key Wild Plants (NPKWP) was promulgated by the Ministry of Forestry and the Ministry of Agriculture in September 1999 and authorized by the State Council. This Catalogue includes 305 species with representatives from 92 families and 194 genera, which were classified into two protection categories. The NPKWP is the key reference employed by Chinese administrative departments to protect and manage endangered and/or economically important wild plants. Because DNA barcoding makes it possible to identify plants using vegetative and/or small tissue fragments, it allows administrative staff to identify NPKWP without taxonomic specialists. As an important part of the Next-Generation Flora (iFlora) project led by the Kunming Institute of Botany, Chinese Academy of Sciences, we built a rapid identification system for the NPKWP. Firstly, we collected 90% of the plant species on the NPKWP and their closely related species and then sequenced the plant DNA barcoding loci, rbcL, matK, ITS and trnH-psbA. This work led to the development of a system based on DNA barcodes, as well as on morphological descriptions,digital images, and geographic information. For species identification, a user may input a query barcode sequence into the platform and the system rapidly provides the most closely related species (NPKWP or not). The user can then use morphological features, photos, and geographic information in the system to obtain a final identification. |
