Determining the role of plant mitochondrial membrane functions in respiratory acclimation to the cold

Abstract

Unlike mammalian mitochondria, plant mitochondria must operate over a wide temperature range. Looking at the impact of chilling stress on mitochondrial membrane functions, it was discovered that at 4°C, the plant mitochondrial ATP synthase is differentially inhibited compared to other elements of the respiratory pathway. This effect, which is most pronounced on the only complex of the respiratory chain that physically rotates, cannot be overcome by cold acclimation of plants. This mechanism adds a new element to the respiratory acclimation model and provides a direct means of temperature perception by plant mitochondria.
