Mitochondrial dysfunction under stress
noun phrasePronunciation: /ˌmɪtəˈkɒndriəl ˌdɪsˈfʌŋkʃən/
Impairment of mitochondrial structure and function during abiotic stress, including reduced ATP production, membrane depolarization, and increased ROS generation. This compromises cellular energy availability and metabolic homeostasis.
Plain English
The breakdown of plant cell powerhouses during stress, reducing energy production and increasing cellular damage.
Etymology & History
Usage
"Mitochondrial dysfunction under heat stress reduces ATP synthesis, limiting the plant's capacity for stress defense."
Style guide notes: Specify the type of dysfunction (structural, enzymatic, genetic) when discussing mitochondrial impairment.
