On the mechanism for winter stem pressure build-up in walnut trees

The paper explains winter stem pressure build-up in walnut trees through a physical model showing sugar concentration imbalances drive vessel pressurization.

Freeze dehydration vs. supercooling in tree stems: physical and physiological modelling

The paper develops a multiphysics model to study cell dehydration and supercooling in tree stems during freezing and thawing, showing how these mechanisms protect against intracellular freezing.

Hydraulic adjustments of Scots pine colonizing a harsh environment on volcano slopes

This study examines hydraulic and leaf trait adjustments in Scots pine trees on volcano slopes under drought conditions, finding that slope trees prioritize hydraulic safety over growth.

Pathogen-derived mechanical cues regulate the spatio-temporal implementation of plant defense

The paper shows that mechanical cues from fungal pathogens trigger immunity in distant plant cells through changes in cell wall tension and cortical microtubule reorganization.

Stem bending generates electrical response in poplar

Poplar stem bending induces an electrical response with high speed and strong decrement.

Seasonal and long-term consequences of esca on grapevine stem xylem integrity

This study examines how esca disease affects xylem integrity in grapevines, showing that tyloses cause hydraulic failure in symptomatic shoots, but not in asymptomatic ones.

Plasticity of the xylem vulnerability to embolism in poplar relies on quantitative pit properties rather than on pit structure

The paper investigates how poplar trees adjust their xylem vulnerability to embolism under different environmental conditions, finding that changes in quantitative pit properties, not structure, drive this plasticity.

Modelling the spatial crosstalk between two biochemical signals explains wood formation dynamics and tree-ring structure

A dynamical model shows that two interacting signals, auxin and cytokinin/TDIF, can explain wood formation dynamics and tree-ring structure in conifers.

The cap size and shape of Arabidopsis thaliana primary roots impact the root responses to an increase in medium strength

The paper investigates how changes in root cap size and shape of Arabidopsis thaliana affect root responses to medium strength, showing that proper root cap formation is necessary for these responses.
