Anaerobic respiration induction
noun phrasePronunciation: /ˌænəˈroʊbɪk ˌrɛspəˈreɪʃən ɪnˈdʌkʃən/
The activation of alternative respiratory pathways that function without oxygen, including fermentation processes and the ethanol and lactate fermentation cycles. This response occurs when roots experience hypoxic or anoxic conditions due to waterlogging or flooding.
Plain English
When plants cannot access oxygen, they switch to breathing pathways that don't require oxygen to survive.
Etymology & History
Usage
"Anaerobic respiration induction in rice roots enables survival during prolonged submergence in paddies."
Style guide notes: Specify which fermentation products accumulate (ethanol, lactate) when discussing specific stress responses.

Frequently Asked Questions
What triggers anaerobic respiration in plants?
Waterlogging, flooding, or soil compaction that restricts oxygen availability to root tissues triggers this response.
Is anaerobic respiration as efficient as aerobic respiration?
No, anaerobic respiration produces much less ATP per glucose molecule, making it less energy-efficient.
Why Test Candidates on This?
Essential for understanding flood tolerance mechanisms in crops and predicting yield loss under waterlogging.
