Abstract

Mitochondrial transcription rate and RNA steady-state levels were examined in shoots of Arabidopsis seedlings. The shoots were treated with inhibitors of complex III and IV of the cytochrome pathway (CP) and with an inhibitor of the alternative oxidase (AOX) of the mitochondrial electron transport chain. The inhibition of AOX and CP complexes III and IV affected transcription and transcript levels in different ways. CP and AOX inhibitors had opposite effects. Our data support the idea that the redox state of the electron transport chain is involved in the regulation of mitochondrial gene expression at transcriptional and post-transcriptional levels.<br /> (Copyright © 2014 Elsevier B.V. and Mitochondria Research Society.
