DOI: 10.1093/jxb/eraa231
Abstract: Photosynthetic efficiency of plants in different environments is controlled by stomata, hydraulics, biochemistry and mesophyll conductance (gm). Recently, gm was demonstrated as the key limitation of photosynthesis in gymnosperms. However, its values across gymnosperms varied… read more here.

DOI: 10.1093/jxb/erab320
Abstract: Mesophyll conductance (gm) is an important factor limiting photosynthesis. However, gm response to long-term growth in variable [CO2] is not well understood, particularly in crop plants. Here, we grew two cultivars of wheat (Halberd and… read more here.

DOI: 10.1093/jxb/ery296
Abstract: Abstract Mesophyll conductance (gm) has been shown to affect photosynthetic capacity and thus the estimates of terrestrial carbon balance. While there have been some attempts to model gm at the leaf and larger scales, the… read more here.

DOI: 10.1093/plphys/kiad173
Abstract: Abstract Mesophyll conductance to CO2 from the intercellular air space to the CO2–H2O exchange site has been estimated using δ18O measurements (gm18). However, the gm18 estimates are affected by the uncertainties in the δ18O of… read more here.

DOI: 10.1104/pp.20.00328
Abstract: It has been argued that accumulation of nonstructural carbohydrates triggers a decrease in Rubisco content, which downregulates photosynthesis. However, a decrease in the sink-source ratio in several plant species leads to a decrease in photosynthesis… read more here.

DOI: 10.3390/plants7030062
Abstract: Whether the mesophyll conductance to CO2 movement (gm) within leaves of C3 plants changes with CO2 concentration remains a matter of debate, particularly at low CO2 concentrations. We tested for changes in gm over the… read more here.
