Functional status of xylem through time

Water transport in vascular plants represents a critical component of terrestrial water cycles and supplies the water needed for the exchange of CO2 in the atmosphere for photosynthesis. Yet, many fundamental principles of water transport are dif …

Beyond porosity: 3D leaf intercellular airspace traits that impact mesophyll conductance

The leaf intercellular airspace (IAS) is generally considered to have high conductance to CO2 diffusion relative to the liquid phase. While previous studies accounted for leaf-level variation in porosity and mesophyll thickness, they omitted 3D IAS …

New frontiers in the three-dimensional visualization of plant structure and function

Novel patterns of hysteresis in the response of leaf-level sap flow to vapor pressure deficit

Recent methodological advances toward measuring sap flow on small- diameter stems allow for near continuous monitoring of leaf-level water flux in response to naturally varying environmental conditions. Elucidating the response functions of sap flow …

Determining the water dynamics of flowering using miniature sap flow sensors

Angiosperms dominate almost every ecosystem globally, and for the vast majority, flowering is vital to successful reproduction, yet little work has characterized the dynamics of water use during flowering and its impacts on the reproductive biology …
