Abstract
In photosynthetic cells, mitochondrial respiration is of major importance not only in the dark but also in the light. Important progress has been made in our understanding of the roles played by mitochondria in light. The light signal is likely to reach cellular compartments such as the mitochondrion and the nucleus via different chloroplast-originated redox messages. The potential involvement of these messages in the regulation of mitochondrial biogenesis and activity by light is discussed in view of the available experimental data.
