proteomics
nounPronunciation: /ˌproʊtiˈoʊmɪks/
The large-scale study of protein expression, modification, and function in plant responses to abiotic stress conditions.
Full Definition
Proteomics is the comprehensive analysis of the entire protein complement expressed by an organism, tissue, or cell under specific conditions. In abiotic stress research, proteomics involves the systematic identification, quantification, and functional characterization of proteins that are differentially expressed or modified in response to environmental stresses such as drought, salinity, temperature extremes, or heavy metals. This approach provides insights into the molecular mechanisms underlying stress tolerance and helps identify potential targets for crop improvement through breeding or biotechnology.
Plain English
The study of all the proteins that plants make when they're stressed by harsh environmental conditions.
In Editorial Context
A key omics technology that requires careful experimental design description and appropriate statistical analysis for publication in high-impact journals.
Etymology & History
Emerged following the Human Genome Project as focus shifted from genes to functional proteins
Originally developed for medical research but rapidly adopted in plant biology for understanding stress responses
Usage
"The proteomic analysis revealed 127 differentially abundant proteins in heat-stressed wheat leaves, including key enzymes involved in antioxidant defense pathways."
Usage note: Should be accompanied by appropriate statistical analysis and functional annotation when presenting results
Context: Molecular biology research, systems biology, stress physiology, biotechnology
Region: international
Also known as
Don't confuse with
Sometimes confused with transcriptomics, but proteomics studies actual proteins rather than RNA transcripts
