| leaf respiration and alternative oxidase in field-grown alpine grasses respond to natural changes in temperature and light. | • we report the first investigation of changes in electron partitioning via the alternative respiratory pathway (ap) and alternative oxidase (aox) protein abundance in field-grown plants and their role in seasonal acclimation of respiration. • we sampled two alpine grasses native to new zealand, chionochloa rubra and chionochloa pallens, from field sites of different altitudes, over 1 yr and also intensively over a 2-wk period. • in both species, respiration acclimated to seasonal changes in tem ... | 2010 | 21128944 |
