Abstract
This article comments on:Stutz SS, Anderson J, Zulick R, Hanson DT. 2017. Inside out: efflux of carbon dioxide from leaves represents more than leaf metabolism. Journal of Experimental Botany 68, 2849–2857.
Highlights
Knowledge of the processes of carbon (C) allocation and cycling in plants and ecosystems is important for understanding the terrestrial C cycle as a whole and changes as a result of anthropogenic impacts
The CO2 efflux from a plant organ was attributed to metabolic reactions and activity only in that same organ
On the other hand, substrate supply for respiration, which is indirectly coupled to environmental drivers, controls respiratory CO2 fluxes (Högberg and Read, 2006)
Summary
Knowledge of the processes of carbon (C) allocation and cycling in plants and ecosystems is important for understanding the terrestrial C cycle as a whole and changes as a result of anthropogenic impacts. A major new challenge became obvious: CO2 efflux is affected by the catabolic metabolism of a given organ, and by the respiration rate of plant compartments coupled via the transpiration stream to that organ.
