Physiological Genomics publishes results of a wide variety of studies from human and from informative model systems with techniques linking genes and pathways to physiology, from prokaryotes to eukaryotes. The Journal encourages the submission of research that links genes to cell replication, development, metabolic function, cell signal transduction and intracellular signaling pathways, tissue and organ function, and whole organism function. Physiological Genomics encourages the utilization of approaches ranging from expression profiling, assays for molecular interactions, natural and directed gene alteration, selective breeding studies, gene identification, and the assessment of gene/environment interaction. The Journal welcomes important new technologies and concepts that enhance the study of functional genomics. The Journal encourages publication of new computational approaches, integrative models, and image analysis predictive of gene function. Physiological Genomics also publishes invited reviews and perspectives that enhance the understanding of the link between genetics and physiology. The Journal is committed to rapid peer review to ensure the publication of high-quality papers and timely news and review articles.
