title: [Effect of low temperature on electron transport in plant mitochondria respiratory chain].
abstract: The etiolated 2.5-day winter wheat sprouts were chilled at 3 degrees C during 24 to 144 hours. After 24 h cooling, shoot intact mitochondria showed a high degree of activation of the alternative oxidase, which was measured as sodium azide and benzohydroxamate sensitivity of the organelles respiration with succinate as a substrate. The role of the alternative oxidase in limiting the level of reactive oxygen species produced in the stressed plant tissues is discussed.
