Abstract

  Environmental, biotic and abiotic stresses applied to plants are well known to induce oxidative stress in plant cells. These stresses alter plant metabolism, growth and development and, at their extremes, can lead to death. Recently, a number of studies have begun to examine the changes that occur within plant mitochondria following the induction of oxidative stress. The accumulation of reac- tive oxygen species and reactive nitrogen species, changes in protein abundance and their interactions in mitochondria following exposure to external stress, and the role of these changes in signaling beyond mitochondria, combine to define the importance of mitochondria as environmental sensors. In this mini-review we will spot light on the major metabolic changes occurred in plant mitochondria as induced by oxidative stress.
