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 ...

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.

GENOTYPICALY IDENTIFYING WHEAT MESOPHYLL CONDUCTANCE REGULATION UNDER PROGRESSIVE DROUGHT STRESS

Frontiers in Plant Science, 2016
Photosynthesis limitation by CO2 flow constraints from sub-stomatal cavities to carboxylation sites in chloroplasts under drought stress conditions is, at least in some plant species or crops not fully understood, yet. Leaf mesophyll conductance for CO2 (

Mesophyll diffusion conductance to CO2: An unappreciated central player in photosynthesis [PDF]

Plant Science, 2012
Mesophyll diffusion conductance to CO(2) is a key photosynthetic trait that has been studied intensively in the past years. The intention of the present review is to update knowledge of g(m), and highlight the important unknown and controversial aspects that require future work.

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

Mesophyll conductance: the leaf corridors for photosynthesis [PDF]

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 ...

Mesophyll conductance in cotton bracts: anatomically determined internal CO2 diffusion constraints on photosynthesis. [PDF]

Journal of Experimental Botany, 2018
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 potential contribution of gm to the ...

Variation in mesophyll conductance among Australian wheat genotypes

Functional Plant Biology, 2014
CO2 diffusion from substomatal intercellular cavities to sites of carboxylation in chloroplasts (mesophyll conductance; gm) limits photosynthetic rate and influences leaf intrinsic water-use efficiency (A/gsw). We investigated genotypic variability of gm and effects of gm on A/gsw among eleven wheat (Triticum aestivum L.) genotypes under light ...

Have We Selected for Higher Mesophyll Conductance in Domesticating Soybean? [PDF]

Plant Cell Environ
Soybean ( Glycine max [L.] Merr) is among the most important agricultural seed crops and source of vegetable protein. Further yield improvements per unit land area are needed to meet future demand and avoid destruction of more natural lands. Mesophyll conductance (

Estimating mesophyll conductance to CO2: methodology, potential errors, and recommendations. [PDF]

Journal of Experimental Botany, 2009
The three most commonly used methods for estimating mesophyll conductance (g(m)) are described. They are based on gas exchange measurements either (i) by themselves; (ii) in combination with chlorophyll fluorescence quenching analysis; or (iii) in combination with discrimination against (13)CO(2).
