metabolomics
nounPronunciation: /mɛtəˈbɒləmɪks/
The comprehensive study of small molecule metabolites within biological systems. A systems biology approach used to understand plant responses to environmental stresses.
Full Definition
Metabolomics is the systematic identification and quantification of all metabolites present in a biological system at a specific time point. In abiotic stress research, it provides insights into the biochemical pathways and metabolic networks that plants employ to cope with environmental challenges. This omics approach complements genomics and proteomics by revealing the functional endpoints of cellular processes. Metabolomic profiling helps researchers understand how plants redistribute resources, synthesize protective compounds, and maintain cellular homeostasis under stress conditions.
Plain English
The study of all the small chemical compounds that cells produce, helping scientists understand how plants change their chemistry when stressed by things like drought or cold temperatures.
In Editorial Context
A research methodology frequently featured in high-impact abiotic stress journals, requiring specialized analytical chemistry expertise and often involving large datasets that benefit from supplementary data repositories and detailed methodological descriptions.
Etymology & History
Emerged as analytical chemistry techniques advanced enough to measure hundreds of metabolites simultaneously, following the success of genomics and proteomics
Initially focused on human disease, expanded to plant biology in early 2000s as stress research became more systems-oriented
Usage
"The manuscript's metabolomic analysis revealed significant changes in amino acid and sugar metabolism under salt stress, requiring additional statistical validation before publication."
Usage note: Often paired with other omics approaches; requires clear methodology description for reproducibility
Context: Research papers, grant applications, methodology sections, data analysis descriptions
Region: international
Also known as
Don't confuse with
Sometimes confused with targeted metabolic pathway studies, but metabolomics implies comprehensive, unbiased analysis
