【科技日报】大属植物分类难题解决 全球蒿属植物族谱绘制成功

Core Viewpoint - The research team from the Chinese Academy of Sciences has successfully constructed the most comprehensive phylogenetic framework for the Artemisia genus, addressing long-standing classification challenges and proposing a new global classification system for these plants [1][2]. Group 1: Research Significance - The Artemisia genus, which includes over 500 species, plays a crucial role in global biodiversity and has significant ecological, medicinal, and chemical applications [1][2]. - Despite its importance, the classification of the Artemisia genus has been historically underdeveloped, with a lack of a robust phylogenetic framework hindering research and utilization [1][2]. Group 2: Research Methodology - The research team conducted extensive field surveys and sample collections over several years to establish the new phylogenetic framework [2]. - The study analyzed 20 key morphological traits to understand their evolutionary patterns and classification value on a global scale [2]. Group 3: New Classification System - The new classification system divides the Artemisia genus into 8 subgenera and 24 groups, providing clear classification for over 99.6% of the species [2]. - This system clarifies the phylogenetic relationships among various groups and offers a practical identification framework based on morphological traits for researchers unable to conduct molecular experiments [2]. Group 4: Future Developments - To promote global sharing of the research findings, the team plans to release a multilingual second edition of the Artemisia phylogenetic and classification diagram (APT II) for use by researchers and industry developers [4]. - The team has also initiated research for a third edition (APT III) to continue advancing the systematic study of global Artemisia plants [4].
