TL;DR: It is argued that abandoning the iso/anisohydric terminology and returning to a more fundamental hydraulic framework would provide a stronger foundation for species comparisons and ecological predictions.

TL;DR: Magnetic resonance imaging was used to continuously monitor xylem cavitation and flow rates in the stem of an intact vine during 10 d of dehydration and showed that complete stomatal closure preceded the appearance of embolism in the leaves and the stem by several days.

TL;DR: For angiosperms, whose subsidiary cells give up large volumes to allow large stomatal apertures at the cost of potentially large wrong-way responses, vein collapse could make an important contribution to these plants’ ability to transpire near the brink of cavitation-inducing water potentials.

TL;DR: This work focuses on how air-seeding occurs at the level of pit membranes, raising the question of whether capillary failure is an appropriate physical model and addresses methodological uncertainties that affect the authors' ability to infer the formation of embolism and its reversal in plant stems.
