    ..The Delta(18)O in these C(4) grasses is similar to low Delta(18)O previously measured in C(4) dicots which contain 2.5 times the leaf CA activity, suggesting that leaf CA activity is not a predictor of Delta(18)O in C(4) plants...

    Plant Physiol 142:662-72. 2006
    ..Furthermore, uncertainties in the isotopic composition of water at the site of exchange may also limit the ability to accurately predict theta in C(4) plants...

    Molecular Plant Physiology Group, Research School of Biological Sciences, Australian National University, Canberra, Australian Capital Territory 2601, Australia
    Plant Physiol 141:232-42. 2006
    ..Our data indicate that the extent of CA activity in C4 leaves needs to be taken into account when using Delta13C and/or delta13C to model the response of C4 photosynthesis to changing environmental conditions...

    ..6) in the wild-type and Pp mutant but increased to 0.9 in the pp mutant. We conclude that in vitro carbonic anhydrase activity overestimated as compared to values determined from Delta(18)O in wild-type plants...
