The partial pressure of CO<sub>2</sub> at the sites of carboxylation within chloroplasts depends on the conductance to CO<sub>2</sub> diffusion from intercellular airspace to the sites of carboxylation, termed mesophyll conductance (<i>g</i> <sub>m</sub>). We investigated how <i>g</i> <sub>m</sub> varies with leaf age and through a tobacco (<i>Nicotiana tabacum</i>) canopy by combining gas exchange and carbon isotope measurements using tunable diode laser spectroscopy. We combined these measurem ...[more]
