Four plus one: vacuoles serve in photorespiration

Stefan Timm et al. Trends Plant Sci. 2023 Dec.

Abstract

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

Keywords: compartmentalization; cytosolic bypass; glycerate; metabolic repair; metabolite transport.
