Discovery Projects - Grant ID: DP140100488

Funded Activity Summary

Temperature response and thermal acclimation of mesophyll conductance. Photosynthetic rate and efficiency depend on diffusion of carbon dioxide from the atmosphere into leaf mesophyll cells. Carbon dioxide diffusion is affected by temperature, but we lack knowledge of how this varies between plant species. Stable isotope methodology will be used to characterise the temperature response of this carbon dioxide diffusion step. Plants from contrasting climates will be grown in different temperature regimes to reveal the extent of variation in adaptation and acclimation to temperature. This will provide new insights towards modifying photosynthesis to increase crop yield and it will also improve forecasting of global atmospheric carbon dioxide fluxes derived from the analysis of atmospheric isotope data.
