Beschreibungen/Notizen

• Leaves are a nexus for the exchange of water, carbon, and energy between terrestrial plants and the atmosphere. Research in recent decades has highlighted the critical importance of the underlying biophysical and anatomical determinants of CO2 and H2O transport, but a quantitative understanding of how detailed 3D leaf anatomy mediates within-leaf transport has been hindered by the lack of a consensus framework for analyzing or simulating transport and its spatial and temporal dynamics realistically, and by the difficulty of measuring within-leaf transport at the appropriate scales. We discuss how recent technological advancements now make a spatially explicit 3D leaf analysis possible, through new imaging and modeling tools that will allow us to address long-standing questions related to plant carbon–water exchange. Plant biologists have long resorted to highly simplified 1D or 2D imaging methods and modeling to study fundamentally 3D leaf processes of CO2 and H2O transport. Recent advances in imaging and computational technology are enabling a data-rich scientific pipeline that integrates leaf 3D measurement, anatomical modeling, and biophysical simulation. Adopting a 3D approach is not only critical for testing when dimensionality reduction is reliable and accurate, but also promises to deliver insights about: (i) fundamental processes of leaf CO2 and H2O transport and exchange, (ii) the translation of leaf anatomical diversity to functional diversity, and (iii) fine-scale CO2 and H2O exchange processes in broader-scale models.
