Provided herein is a system and method for analyzing microarray data (transcriptome profiles), metabolite data (metabolome profiles), protein level data (proteome profiles), or any combination thereof to determine the biochemical pathways affected by a treatment. The system and method can be used to generate biochemical pathway information for any organism for which metabolic profile data can be obtained. The system and method may allow users to query the pathways generated and to filter the results of queries based on the -omic profile data, pathways involving molecules of interest, notions of biochemical importance, milestone molecules, and other factors. The system and method may also be suitable for discovery of regulatory sequences in genes. In an exemplary use, the system and method can be utilized to identify three genes involved in "de novo" ammonia "biosynthesis" that are induced by light, and was able to identify a putative cis-element, GWTTGTGG, that is likely involved in the regulation of those genes.
