Leaf Optics:

Light absorption, photosynthesis, and hydraulics Light absorption within the leaf not only drives the photosynthetic uptake of CO2, it generates internal temperature gradients that control transpiration rates. Despite its importance for natural and agricultural systems, our understanding of the physical interaction between light and leaves, or leaf optics, is quite …

In-vivo Starch Quantification:

Spatial Mapping via X-ray MicroCT Imaging and Machine Learning Starch is the central energy storage molecule used by plants to fuel respiration and growth during periods of limited or no photosynthesis.¬† Recently, the relative starch concentration of plants entering drought was linked to mortality probability, as the relative pools of …

3D Leaf Geometry:

Controls on Photosynthesis and Transpiration Leaves are sophisticated 3D bioreactors that have been evolutionarily optimized to inhabit Earth’s broad range of environmental conditions. The rate of CO2 and H2O transport between the atmosphere and chloroplasts are key controls on plant photosynthetic capacity, productivity, and survival. Atmospheric CO2 enters and transpirational¬†H2O …

Plant Vascular Recovery:

Underlying Carbon-Water Transport Mechanisms The plant vascular system transports water from the soil into the atmosphere and distributes assimilated carbon, as carbohydrates, throughout the plant. These carbohydrate and hydraulic systems are, thus, adapted to function within the typical range of local climatic variability. Rising temperatures and changing precipitation, however, are …
