英文摘要：

Plant metabolomics is a newly emerging ＇omics＇, which has been widely used in plant science research. Data analysis and data mining are the hotspots and the most difficult aspects of plant metabolomics research. In this review, we summarized the major aspects of data analysis and data mining, including the characteristics of metabolomics data, procedure of data analysis, major software packages and public databases. Also data pre- processing, the statistic principle and methods used in metabolomics data analysis, and the characteristics of major software and public databases were introduced in detail. Finally, we discussed the current situation and prospect of plant metabolomics data analysis.
