AraCyc can help you find these connections! Arabidopsis Metabolic EnCyclopedia Database of metabolic pathways found in Arabidopsis
www.arabidopsis.org/biocyc/ (TAIR) www.plantcyc.org/ARA (Plant Metabolic Network)
Everyone is studying metabolism
Many biological processes connect to metabolism Drought tolerance – changes in osmolyte concentrations Hormone signaling – biosynthesis and degradation of hormones Photosynthesis – chlorophyll production and ROS scavenging Translation – amino acid biosynthesis and riboswitching Plant defense – phytoalexin synthesis
Your favorite process . . .

OMICS Viewer to the rescue . . . Overlay experimental data on a metabolic map
Transcript data (for enzymes)
Proteomic data (for enzymes)
Metabolomic data
Use multiple data sources
Your data Publicly available data
Gene Expression Omnibus NASC Proteomics Database NSF2010 Metabolomics Many more . . .
Generate new testable hypotheses about your favorite gene metabolite biological process etc.

Addressing common research conundrums . . .
My (single/double/triple/quadruple) mutant has “no phenotype”!!!! Compare transcript levels / protein levels / metabolite levels in wild-type and mutant plants using the OMICS viewer Look for “hidden” perturbations in metabolism
I have a mutant with a defect in (biological process) . . . but I don’t know the mechanism Use the OMICS viewer to compare data from WT and mutant plants Download publicly available data sets related to the biological process Scan for affected areas of metabolism
I just did a microarray experiment and a bunch of metabolic enzymes popped up . . . Use the OMICS Viewer to quickly identify metabolic pathways that are up- or down-regulated
And many more . . .
