摘要
Comparative metabolomics plays a crucial role in investigating gene function,exploring metabolite evolution,and accelerating crop genetic improvement.However,a systematic platform for intra-and crossspecies comparison of metabolites is currently lacking.Here,we report the Plant Comparative Metabolome Database(PCMD;http://yanglab.hzau.edu.cn/PCMD),a multilevel comparison database based on predicted metabolic profiles of 530 plant species.The PCMD serves as a platform for comparing metabolite characteristics at various levels,including species,metabolites,pathways,and biological taxonomy.The database also provides a number of user-friendly online tools,such as species comparison,metabolite enrichment,and ID conversion,enabling users to perform comparisons and enrichment analyses of metabolites across different species.In addition,the PCMD establishes a unified system based on existing metabolite-related databases by standardizing metabolite numbering.The PCMD is the most speciesrich comparative plant metabolomics database currently available,and a case study demonstrates its ability to provide new insights into plant metabolic diversity.
