Ethylene Signaling Enhances Mitochondrial Stress Tolerance Independently of the Transcription factor ANAC017 in Arabidopsis

Mitochondria are central to plant metabolism, yet the diversity of mechanisms plants use to cope with mitochondrial stress and its implications in cellular signaling are not fully understood. In this study, we analyzed Arabidopsis noxy (nonresponding to oxylipins) mutants affected in 9-HOT (9(S)-hydroxy-10,12,15-octadecatrienoic acid) signaling, mitochondrial function and ethylene (ET) signaling to dissect plant responses to a range of mitochondrial stresses, including inhibitors of all electron
