Funded Activity Summary

Answering longstanding plant ecology questions with new technology: the effects of changes in leaf proteins with age. Total leaf nitrogen is important for major processes in ecosystems. It is used as a predictor for carbon fixation because photosynthesis proteins are a large fraction of leaf nitrogen. Yet leaf nitrogen may also be allocated to stress-response and defense-related proteins at the expense of photosynthesis proteins. Our working hypothesis might explain two important ecological patterns: the decline of photosynthetic nitrogen use efficiency with leaf age; and, low and variable nitrogen recovery levels from senescent leaves across species and habitats. New quantitative proteomics methods together with protein functional categorisation can answer these questions across dozens of Australian native plant species.
