“…Its action could be the unifying factor in the induction of AOX by such disparate experimental conditions as chilling and the application of antimycin A, oligomycin, an inhibitor of the mitochondrial ATPase (Saisho et al, 2001), or chloramphenicol, an inhibitor of mitochondrial protein synthesis that prevents synthesis of an intact cytochrome pathway (Vartapetian et al, 1975;Zhang et al, 1996aZhang et al, , 1999. Although counterintuitive, a mitochondrial uncoupler (carbonyl cyanide p-trifluorouethoxyphenylhydrazone (FCCP)) applied to cultured tobacco cells also induced increased AOX capacity (Zhang et al, 2003). Here, too, ROS appear responsible: FCCP causes an increase in glycolysis, resulting in more reductant and an overreduction of the ETC with increased ROS production as a consequence (Zhang et al, 2003).…”
