Mineral nutrient remobilization
nounPronunciation: /ˈmɪnərəl ˈnjuːtriənt ˌriːmoʊbɪləˈzeɪʃən/
The translocation of minerals such as nitrogen, phosphorus, and potassium from senescing leaves and stems to developing organs and seeds during nutrient stress or reproductive stages. This process maintains nutrient availability for growth despite reduced uptake from soil.
Plain English
Plants move valuable nutrients from old leaves to new growth when soil nutrients are scarce.
Etymology & History
Usage
"Mineral nutrient remobilization during grain filling ensured adequate phosphorus supply despite low soil availability."
Style guide notes: Hyphenate 'nutrient-remobilization' when used as compound modifier; maintain lower-case for standard usage.

Frequently Asked Questions
Which nutrients are most commonly remobilized in plants?
Nitrogen, phosphorus, and potassium are preferentially remobilized due to their high mobility and critical roles in growth.
How does nutrient stress trigger remobilization?
Low soil nutrient availability activates signaling pathways that increase nutrient resorption from senescing tissues.
Why Test Candidates on This?
Important for crop-breeding programs focusing on nutrient-use efficiency and stress tolerance.
