Abstract
The ability to couple photosynthetic electron transport and redox poise to plastid gene expression enables plants to respond to environmental conditions and coordinate nuclear and chloroplast activities in order to maintain photosynthetic efficiency. The plastid redox regulatory system serves as a paradigm for understanding redox-regulated gene expression. In this review, we will focus on posttranscriptional events of redox-regulated gene expression in the chloroplast. As redox regulation of enzymatic activities in the chloroplast will be covered in other reviews in this volume, as will discussions on the redox regulation of chloroplast transcription, we will concentrate on the available evidence for redox regulation of chloroplast translation, and mRNA splicing and turnover.
