Photorespiratory metabolism is essential for plants to maintain functional photosynthesis in
an oxygen‐containing environment. Because the oxygenation reaction of Rubisco is …

A significant resistance to CO2 diffusion is imposed by mesophyll tissue inside leaves.
Mesophyll resistance, rm (or its reciprocal, mesophyll conductance, gm), reduces the rate at …

Understanding the short‐term responses of mesophyll conductance (gm) and stomatal
conductance (gsc) to environmental changes remains a challenging yet central aspect of …

Stable isotopes are commonly used to study the diffusion of CO2 within photosynthetic plant
tissues. The standard method used to interpret the observed preference for the lighter …

On the occasion of the 40th anniversary of the publication of the landmark model by
Farquhar, von Caemmerer & Berry on steady‐state C3 photosynthesis (known as the “FvCB …

The response of mesophyll conductance (gm) to CO2 plays a key role in photosynthesis and
ecosystem carbon cycles under climate change. Despite numerous studies, there is still …

Besides stomata, the photosynthetic CO2 pathway also involves the transport of CO2 from
the sub-stomatal air spaces inside to the carboxylation sites in the chloroplast stroma, where …

The conductance of carbon dioxide (CO2) from the substomatal cavities to the initial sites of
CO2 fixation (gm) can significantly reduce the availability of CO2 for photosynthesis. There …

The carbon atoms deposited in tree rings originate from the CO2 in the atmosphere to which
the tree's canopy is exposed. Thus, the first control on the stable carbon-isotope composition …

Abstract Main Conclusion Light quality and intensity regulate plant mesophyll conductance,
which has played an essential role in photosynthesis by controlling leaf structural and …
