Translational regulation plays a major role in plant gene expression.
Recent advances have been made in understanding how this mechanism of
control is directed in the chloroplast as well as in the cytoplasm. Ou
r knowledge of translational regulation in plant mitochondria, however
, is limited. Translational control of gene expression in yeast mitoch
ondria suggests that similar mechanisms will also play a significant r
ole in the expression of plant mitochondrial genes.
