Session Proposal: Carbon Allocation Dynamics: From Plant to Ecosystem Scale (AGU25)

B022
Carbon Allocation Dynamics: From Plant to Ecosystem Scale

Session ID#: 249597

Session Description:
The partitioning of assimilated carbon to the production of different tissues, functional pools, and metabolic pathways determines their chemical composition, longevity, exposure to different decomposition pathways, and, ultimately, the proportion that is retained in long-term soil carbon pools. While carbon storage and the fluxes of photosynthesis and respiration have been extensively studied, functional understanding of carbon allocation and the role of non-structural carbohydrates remains poor and are among the greatest remaining uncertainties in ecosystem carbon cycle models. Recent evidence increasingly suggests that carbon allocation is the outcome of both source- and sink-driven controls, calling for the revision of how this process is currently characterized in models. In this session, we invite observational, experimental, and modeling studies that contribute to improved understanding of the magnitude and controls of carbon allocation within plants, and the plant-microbe-soil system more broadly.
