An improved theory for calculating leaf gas exchange more precisely accounting for small fluxes
gas exchange leaf von Caemmerer and Farquhar (vCF)
2023/12/8
The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for...
A systems genetics approach to deciphering the effect of dosage variation on leaf morphology in Populus
Populus leaf morphology plant genomes gene dosage morphological
2023/12/6
Gene copy number variation is frequent in plant genomes of various species, but the impact of such gene dosage variation on morphological traits is poorly understood. We used a large population of Pop...
Single-cell transcriptomics sheds light on the identity and metabolism of developing leaf cells

2023/11/30
As the main photosynthetic instruments of vascular plants, leaves are crucial and complex plant organs. A strict organization of leaf mesophyll and epidermal cell layers orchestrates photosynthesis an...
Higher leaf nitrogen content is linked to tighter stomatal regulation of transpiration and more efficient water use across dryland trees

2023/11/28
The least-cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has to cope with th...
Leaf water potential measurements using the pressure chamber: synthetic testing of assumptions towards best practices for precision and accuracy
leaf water potential plant water relations plant water status pressure bomb pressure chamber water stress
2023/11/28
Leaf water potential (ψ leaf), typically measured using the pressure chamber, is the most important metric of plant water status, providing high theoretical value and information content for multiple ...
Intact leaf gas exchange provides a robust method for measuring the kinetics of stomatal conductance responses to abscisic acid and other small molecules in Arabidopsis and grasses
Stomatalconductance Kinetics Guardcellphysiology Aquaporin
2024/3/5
Guard cells perceive external and internal stimuli and regulate stomatal conductance in plants. With the use of gas exchange analyzers, time-resolved stomatal conductance responses to light intensity,...
A Comparison of in situ Leaf Photosynthesis and Chlorophyll Fluorescence at the Top Canopies in Rainforest Mature Trees
Dipterocarpus cornutus Macaranga gigantea photosynthetic nitrogen use efficiency specific leaf area uppermost canopy
2009/6/10
The top canopy leaves of mature trees are exposed to high solar radiation, regardless of whether they are climax or pioneer trees. We compared leaf physiology and morphology at the top canopies of a c...
