Circadian regulation of photosynthesis and transpiration from genes to ecosystems

Circadian regulation is an endogenous self-sustaining mechanism that drives temporal gene expression and, amongst others, affects the diurnal patterns of photosynthesis (A) and stomatal conductance (gs). Here we review current knowledge on how circadian regulation drives diurnal gas exchange from ge...
