Proteome rebalancing
nounPronunciation: /ˈproʊtiːoʊm ˌriːˈbælænsɪŋ/
The dynamic adjustment of protein abundance and composition in response to abiotic stress, involving coordinated changes in synthesis and degradation of specific proteins to redirect cellular resources. This process enables metabolic repriorization and maintenance of essential functions under limiting conditions.
Plain English
Plants adjust which proteins they make and break down to survive stress with limited resources.
Etymology & History
Usage
"Proteome rebalancing under cold stress redirected nitrogen allocation from growth to stress-protective proteins."
Style guide notes: Often used with specificity markers (e.g., 'salt-induced proteome rebalancing'); maintain as one term.
