Neither xylem collapse, cavitation, or changing leaf conductance drive stomatal closure in wheat

D Corso, S Delzon, LJ Lamarque… - Plant, Cell & …, 2020 - Wiley Online Library
Identifying the drivers of stomatal closure and leaf damage during stress in grasses is a
critical prerequisite for understanding crop resilience. Here, we investigated whether …

Hydraulic variability of tropical forests is largely independent of water availability

CM Smith‐Martin, R Muscarella, WM Hammond… - Ecology …, 2023 - Wiley Online Library

Variation in xylem vulnerability to cavitation shapes the photosynthetic legacy of drought

V Tonet, T Brodribb, I Bourbia - Plant, Cell & Environment, 2024 - Wiley Online Library
Increased drought conditions impact tree health, negatively disrupting plant water transport
which, in turn, affects plant growth and survival. Persistent drought legacy effects have been …

No gas source, no problem: proximity to pre‐existing embolism and segmentation affect embolism spreading in angiosperm xylem by gas diffusion

X Guan, L Pereira, SAM McAdam… - Plant, Cell & …, 2021 - Wiley Online Library
Embolism spreading in dehydrating angiosperm xylem is driven by gas movement between
embolized and sap‐filled conduits. Here we examine how the proximity to pre‐existing …

Xylem resistance to cavitation increases during summer in Pinus halepensis

F Feng, Y Wagner, T Klein… - Plant, Cell & …, 2023 - Wiley Online Library
Cavitation resistance has often been viewed as a relatively static trait, especially for stems of
forest trees. Meanwhile, other hydraulic traits, such as turgor loss point (Ψtlp) and xylem …
