Metabolic flux redistribution
nounPronunciation: /məˈtæbɒlɪk flʌks ˌrɪdɪˈstrɪbjuːʃən/
The reallocation of biochemical pathways and energy resources within plants in response to abiotic stress, prioritizing survival over growth. This involves shifting carbohydrates, nitrogen, and other resources toward stress-protective compounds and away from growth processes.
Plain English
The plant's redirection of biochemical processes toward survival and stress protection instead of normal growth.
Etymology & History
Usage
"Metabolic flux redistribution in cold-stressed Arabidopsis prioritized energy toward membrane stabilization over biomass accumulation."
Style guide notes: Use 'redistribution' rather than 'realignment' to emphasize quantitative changes in pathway flux.

Frequently Asked Questions
How do plants sense and trigger metabolic flux redistribution?
Stress signals (ABA, ROS) activate transcription factors that reprogram gene expression and enzyme activity patterns.
What resources are typically redirected during stress?
Carbon (toward secondary metabolites), nitrogen (toward protective proteins), and energy (toward membrane repair).
