Four plus one: vacuoles serve in photorespiration

Photorespiration is inevitable for oxygenic photosynthesis. It has fas-cinated researchers over decades because of its multicompartmental organization. Recently, Lin and Tsay identified a vacuole glycerate transporter contributing to photo respiratory metabolism under short-term nitrogen depletion. This key finding adds a fifth interacting sub cellular compartment and extends the photorespiratory metabolic re-pair module.
