Mesophyll conductance: walls, membranes and spatial complexity [PDF]
New Phytologist, 2020 SummaryA 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 which Rubisco can fix CO2, increasing the water and nitrogen costs of carbon acquisition.

Photosynthetica, 2020 Our experiment was conducted to understand the effects of foliar sprays of paclobutrazol (PBZ), its mixture with abscisic acid (ABA), or water (control) on leaf carbon-use efficiency (CUEl), photosynthesis, and respiration of Euonymus japonicus seedlings.

BMC Plant Biology, 2021 Background Leaf hydraulic and economics traits are critical for balancing plant water and CO2 exchange, and their relationship has been widely studied. Leaf anatomical traits determine the efficiency of CO2 diffusion within mesophyll structure.

Mesophyll conductance: the leaf corridors for photosynthesis
Biochemical Society Transactions, 2020 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 Rubisco is located. This pathway is far to be a simple and direct way, formed by series of consecutive barriers that the CO2 should cross to be finally assimilated in ...

Modifying mesophyll conductance to optimise photosynthesis in crops [PDF]
, 2023 Mesophyll conductance (gm), the ease with which carbon dioxide can diffuse into and through plant cells, is a promising target for improving photosynthetic rates in plants. Barriers including cell walls, membranes, liquid phases and the anatomy and orientation of the cells and their subcellular organelles impose resistances on carbon dioxide diffusion ...

Temperature responses of mesophyll conductance differ greatly between species [PDF]
Plant, Cell & Environment, 2014 AbstractThe temperature responses of mesophyll conductance (gm) were investigated for nine species using carbon isotope techniques combining tunable diode laser spectroscopy and gas exchange measurements. Species included the evergreen trees Eucalyptus pauciflora and Quercus engelmannii; the tropical evergreen tree Lophostemon confertus; as well as the

Stomatal, mesophyll conductance, and biochemical limitations to photosynthesis during induction [PDF]
Plant Physiology, 2020 Abstract The dynamics of leaf photosynthesis in fluctuating light affects carbon gain by plants. Mesophyll conductance (gm) limits CO2 assimilation rate (A) under the steady state, but the extent of this limitation under non-steady-state conditions is unknown.

Variable mesophyll conductance revisited: theoretical background and experimental implications [PDF]
Plant, Cell & Environment, 2012 ABSTRACTThe CO2 concentration at the site of carboxylation inside the chloroplast stroma depends not only on the stomatal conductance, but also on the conductance of CO2 between substomatal cavities and the site of CO2 fixation. This conductance, commonly termed mesophyll conductance (gm), significantly constrains the rate of photosynthesis.

Legume Science, 2021 Photosynthesis is one of the parameters first affected by freezing stress. So studying the efficiency of photosynthetic parameters could be an effective strategy in screening freezing‐tolerant genotypes.
