- Abstract:
- Leaf respiration (R) plays a vital role in determining global atmospheric CO2 concentrations. At present, global C exchange models assume that the temperature coefficient of R exhibited in short-term measurements can be used to model future rates of R. However, there is growing evidence that R acclimates to longer-term changes in temperature. Acclimation can result in plants maintaining constant daily rates of R. Past studies has suggested that acclimation depends on increases in enzymatic capacity of R; if correct, acclimation will require an additional supply of nitrogen. This research project will establish the extent to which thermal acclimation of leaf respiration is dependent on an adequate supply of nitrogen. To provide a more mechanistic understanding of this relationship, an approach combining intact tissue and isolated mitochondrial studies will be used.
