C4 photosynthetic isotope exchange in NAD-ME- and NADP-ME-type grasses

Cousins, Asaph; Badger, Murray; von Caemmerer, Susanne


Monitoring photosynthetic isotope exchange is an important tool for predicting the influence of plant communities on the global carbon cycle in response to climate change. C4 grasses play an important role in the global carbon cycle, but their contribution to the isotopic composition of atmospheric CO2 is not well understood. Instantaneous measurements of 13CO2 (Δ13C) and C18OO (Δ18O) isotope exchange in five NAD-ME and seven NADP-ME C 4 grasses have been conducted to investigate the difference...[Show more]
