EXPath is a database resource that collects and utilizes expression profiles derived from microarray under various conditions to infer metabolic pathways for six model plants: Arabidopsis thaliana, Oryza sativa, Zea mays, Solanum lycopersicum, Glycine max, and Medicago truncatula. Five main functions in EXPath are as follows.

The current EXPath release (version 2.0) include:
★ Increase model crops from three to six
★ Establish tissue-specific and organ-specific gene expression analysis
★ Construct distinct correlation networks for a group of genes under different conditions
★ Provide regulatory information of transcription factors involved in metabolic pathway or co-expressed gene group
