End-product synthesis depletes the metabolite pools that drive intercellular shuttles in maize, which explains the slow recovery.

Other claims from this paper (5)
- Mechanism After a decrease in irradiance, maize photosynthesis is transiently buffered by energy from large metabolite pools in the energy shuttle and CCM.
- Observation After a decrease in irradiance, maize metabolism takes several minutes to recover to an optimal state for low irradiance.
- Mechanism After an increase in irradiance, maize photosynthesis rises rapidly, linked to build-up of CBC intermediates.
- Mechanism After an increase in irradiance, a further slow rise of maize photosynthesis is linked to gradual accumulation of the large metabolite pools.
- Mechanism Transient imbalances between CO2 pumping and utilization cause further losses of maize photosynthetic efficiency during irradiance transitions.
