Photorespiration is known to be involved in carbon flux in plants, enabling the carbon lost during RuBisCO oxygenation to be recovered. We show that NPF8.4 is a transporter responsible for sequestering the photorespiratory carbon intermediate glycerate into vacuoles during nitrogen depletion, elucidating a novel function for photorespiration in nitrogen flux.
