Signal Pathways for Regulation of Plant Alternative Oxidase Genes’ Expression

Abstract This review deals with important issues in regulation of terminal alternative oxidase (AOX) plant mitochondria, which are currently investigated and discussed. AOX ensures electron transport along the nonphosphorylating cyanide-resistant pathway mitochondrial ETC plays an role maintenance redox balance cell defense against stress. Principal results concerning signaling were obtained works dealing expression АОХ1а gene Arabidopsis thaliana ( AtAOX1a ). Reports about АОХ different species analyzed. Mechanisms transcriptional posttranscriptional control over genes described. The some cis -regulatory elements AtАОХ1а promoter related transcription factors was considered. It shown that transduction signal causing may follow anterograde retrograde pathways. Information ROS-dependent ROS-independent pathways induction is given. A hypothetic sequence events light wheat leaf course greening worked out. Interactions between hormonal pathways, as well by signals plastid origin, In conclusion, it highlighted integrated into common acts a target regulator events.
