2014年4月24日，我园组织的第19届国际植物学大会（International Botanical Congress, IBC）命名法规修订会议第一次预备会在深圳顺利召开。参会代表包括国际植物分类协会（International Association for Plant Taxonomy, IAPT）副会长Sandra Knapp博士、第19届IBC命名法规修订会议报告人Nicholas Turland博士、IAPT秘书长Karol Marhold教授、IAPT命名法规委员会资深成员John McNeill博士，来自中科院植物研究所、中科院微生物研究所、中科院华南植物园、中科院昆明植物研究所、上海辰山植物园科研中心、江苏省中科院植物研究所等科研单位的十余位知名专家，以及将直接参与第19届IBC筹备工作的我园领导和科研人员等。会议主要包括致辞、专家报告和讨论、总结等议程。
本次会议的9个专题报告主要涉及以下内容：1. IBC的发展简史、组织机构及命名法规分委会（Nomenclature Section）的简介和工作流程；2. IAPT的发展简史、职能及其对植物分类研究和命名法规修订的支持；3. 针对发表于电子期刊的分类学处理，墨尔本会议对命名法规的相关修改及其后续影响的评估；4. 第19届IBC命名法规修订分会上可能应用的电子化设备；5. 结合中国植物分类工作中的实例，阐述墨尔本法规中尚存在的部分问题；6. 植物分类学在中国的发展简史及中国学者取得的进展；7. 真菌命名与物种数据库平台的应用；8. 植物命名与物种数据库平台项目的规划和进展；9. 生物命名法规的发展现状及未来的发展方向等。讨论环节中的热点则聚焦于如何使中国分类学家更多地参与到第19届IBC及其命名法规分会的实际工作中（例如在中国成立IAPT分委会），并力求以此为契机将中国分类学研究及国际合作推向新的阶段和新的层次。
The 5th International Barcode of Life Conference is successfully held in Kunming China from 27th to 31th October, 2013. The conference is sponsored by the Chinese Academy of Sciences (CAS) and the International Barcode of Life project (iBOL), and organized by the CAS Kunming Institute of Botany, CAS Kunming Institute of Zoology and the iBOL China National Committee.
Around 450 delegates from 43 countries or regions across the world, including researchers, students, government officials, and private sectors, attend this conference. A total of 24 plenary presentations and 139 parallel presentations were given in the conference, which provided an in-depth exposure to the latest advances in the research and applications of DNA barcoding, as well as a platform to discuss future directions of barcoding research and development. This year is the tenth anniversary of DNA barcoding. The theme of this conference is “Global Change and the Barcode of Life: Challenges and Opportunities", the conference aimed to provide a communication platform for DNA Barcoding research and practices, and to further promote worldwide DNA barcoding practice and biodiversity science.
A Kunming Declaration on the Promotion of DNA Barcoding and Biodiversity Science (attached) is signed and announced at the conference on 31st October. Through the Declaration, an ad hoc governance committee will be formed to be tasked with establishing a proposed international coordinating organization. The organization will be formally launched at the 2015 Sixth International Barcode of Life Conference to promote the excellence in the science of barcoding of all domains of life.
The 5th International Barcode of Life Conference is also sponsored by National Natural Science Foundation of China, Yunnan Baiyao Group Co., Ltd.,,Genome Canada, Life Technologies, CAS Key Laboratory for Plant Diversity and Biogeography of East Asia and State Key Laboratory of Genetic Resources and Evolution.
Incongruence between Nuclear and Chloroplast DNA Phylogenies in Pedicularis Section Cyathophora (Orobanchaceae)
Pedicularis shows high diversity in its corolla form, however, its floral ontogeny has been rarely investigated. In particular, the development of the highly variable upper lip (galea), three broad morphological types of which (beakless and toothless, beakless and toothed, beaked) can be discriminated, remains unknown. We used scanning electron microscopy to investigate the early stages of floral ontogeny in two beaked species, Pedicularis gruina and P. siphonantha. To compare the developmental processes of the three galea types, three species for each type were investigated. Initiations of floral organs in Pedicularis are consistent. Sepal initiations are successive from the lateral-adaxial primordia, followed by the lateral-abaxial ones (these sometimes missing), then the mid-adaxial one (again sometimes missing). The stamens are initiated prior to the petals, or development of petal primordia may be retarded at the early stages in comparison with that of stamen primordia. Four stamen primordia are initiated simultaneously. The five petal primordia are initiated almost simultaneously. Development processes of the upper lip among the three galea types differ in the expansion rates and directions of the cells of the two lobes and these differences govern whether or not a beak and/or teeth are formed on the upper lip. The floral ontogeny of Pedicularis is close to that of Agalinis, which supports the molecular assignment. Floral monosymmetry of Pedicularis is established at the beginning of sepal initiation and is maintained until flowering. The development of the upper lip provides some clues to the evolution of beaked and/or toothed galeas in Pedicularis.
