Nutrient Remobilization
nounPronunciation: /ˈnjuːtriənt ˌriːməʊbɪlɪˈzeɪʃən/
The controlled mobilization and reallocation of essential nutrients from senescing tissues to developing organs during stress conditions, which conserves nutrient resources and extends plant survival. This process involves upregulation of transport proteins and enzymatic breakdown of macromolecules.
Plain English
Plants moving nutrients from old, dying tissues to new growth areas to survive stressful conditions.
Etymology & History
Usage
"Nutrient remobilization from mature leaves to developing grains was enhanced under terminal drought stress."
Style guide notes: Use 'remobilization' as one word; hyphenate only when preceding a noun as modifier.

Frequently Asked Questions
Which nutrients are most commonly remobilized during stress?
Nitrogen, phosphorus, potassium, and magnesium are preferentially remobilized from vegetative tissues.
How does nutrient remobilization help plants survive stress?
It maintains nutrient supply to critical organs like reproductive tissues despite limited external nutrient availability.
Why Test Candidates on This?
Nutrient remobilization is tested in crop stress physiology and agronomic management competency assessments.
