List of omics topics in biology

Inspired by the terms genome and genomics, other words to describe complete biological datasets, mostly sets of biomolecules originating from one organism, have been coined with the suffix -ome and -omics. Some of these terms are related to each other in a hierarchical fashion. For example, the genome contains the ORFeome, which gives rise to the transcriptome, which is translated to the proteome. Other terms are overlapping and refer to the structure and/or function of a subset of proteins (e.g. glycome, kinome).

An omicist is a scientist who studies omeomics, cataloging all the “omics” subfields.^[1]

Omics.org is a Wiki that collects and alphabetically lists all the known "omes" and "omics."^[2]

Envirome	Enviromics	Gene related environment factors (envirome)
Environmental DNA	Environmental omics	Sequencing of ambient DNA
Epigenome	Epigenomics	Epigenetic modifications	Molecular genetics	Epigenomics is the study of the complete set of epigenetic modifications on the genetic material of a cell, collectively known as the epigenome
Exposome (2005)	Exposomics	An individual's environmental exposures, including in the prenatal environment	Molecular genetics	A proposed term and field of study of the disease-causing effects of environmental factors (the "nurture" component of "nature vs. nurture").[5]
Exposome (2009)		Composite occupational exposures and occupational health problems	Occupational safety and health	The proposers of this term were aware of the previous term as used above but proposed to apply the term to a new field.[6][7]
Exome	Exomics	Exons in a genome	Molecular Genetics
Foodome	Foodomics	Food and Nutrition issues related to bioactivity, quality, safety and traceability of foods through the application and integration of advanced omics technologies to improve consumer's well-being, health, and confidence.	Nutrition	The term was first defined in 2009[8]
Genome	Genomics (Classical genetics)	Genes (DNA sequences/Chromosomes)	Genetics	"Genome" refers to the set of all genes in an organism. However, "genome" was coined decades before it was discovered that most DNA is "non-coding" and not part of a gene; thus, "genome" originally referred to the entire collection of DNA within an organism. Today, both definitions are used, depending on the context.[9]
Glycome	Glycomics	Glycans	Glycobiology
Hologenome	Hologenomics	Genomes of community members (i.e., holobionts)	Metagenomics
Humeome	Humeomics	The chemical components of soil humus	Soil science
Interferome	Interferomics	Interferons	Immunology	Also a database of the same name.[10]
Interactome	Interactomics	All interactions		The term "interactomics" is generally not used. Instead, interactomes are considered the study of systems biology.[11][12]
Ionome	Ionomics	Inorganic biomolecules	Molecular Biology
Kinome	Kinomics	Kinases	Molecular Biology	Proteins that add a phosphate group
Lipidome	Lipidomics[13]	Lipids	Biochemistry
Mechanome	Mechanomics	The mechanical systems within an organism
Metabolome	Metabolomics	Metabolites		All products of a biological reaction (including intermediates)
Metagenome	Metagenomics	Genetic material found in an environmental sample	Molecular Biology	The genetic material is assumed to contain DNA from multiple organisms and therefore multiple genomes, hence the inclusion of the prefix meta-.
Metallome	Metallomics	Metals and metalloids
Microbiome	microbiomics	Collection of microorganisms in another organism such as an animal	Microbiology
Obesidome	Obesidomics	Obesity related proteins	Proteomics	Coined by Pardo et al., 2012.[14]
ORFeome	ORFeomics	Open reading frames (ORFs)	Molecular Genetics
Organome	Organomics	Organ interactions	Cellular Signalling / Cell Signaling and Tissue Engineering	The study of crosstalk between organs using physiologically relevant in-vitro models
Parvome	Parvomics	Secondary metabolites	Biochemistry	Coined by Mark Martin and introduced by Julian Davies in 2008, referring to the Latin parvus for "small", and describing the "humungous microbial world of small (secreted) molecules of great structural diversity".[15] See also [16]
Pharmacogenetics	Pharmacogenetics	SNPs and their effect on pharmacokinetics and pharmacodynamics	Pharmacogenomics Genomics
Pharmacogenome	Pharmacogenomics	The effect of changes on the genome on pharmacology	Pharmacogenetics Genomics
Phenome	Phenomics	Phenotypes	Genetics
Physiome	Physiomics	Physiology of an organism
Phytochemome	Phytochemomics	Phytochemicals		The term has been coined by del Castillo et al., 2013, Food Research International, . Phytochemomics is a comprehensive concept aimed to increase the knowledge of phytochemicals' bioactivity which is of growing importance in agricultural, food, medicine and cosmetic sciences
