...) will converge upon traits that avoid embolism during all but the most severe droughts. We evaluated hydraulic traits and drought responses of six common woody tree species from South Africa’s Albany Subtropical Thicket. For each species, we measured laboratory-based xylem vulnerability and pressure-volume...

... and freeze events, embolisms can form in xylem conduits, ceasing the transport of water. Understanding the formation and propagation of embolisms is crucial to predicting species’ responses to a changing climate. We develop a novel spatiotemporal model for embolism propagation, explore the dynamics of xylem...

...:https://dbpia.nl.go.kr/pages/standard-publication-reuse-rights ) Abstract Perennial woody plants accumulate native xylem embolisms over time. However, whether this makes the water transport system more vulnerable to drought-induced dysfunction as the percentage of gas-filled vessels increases is unclear. We tested...

... bacterial movement in the apoplast and the xylem. As a first step to dissect the underlying mechanisms, we analysed the apoplast proteome upon challenge with R. solanacearum in the susceptible tomato cultivar Marmande and in the and resistant Hawaii 7996. Here, we described the xylem proteomes...

... to drought stress is a major cause of forest decline. Many techniques have been developed to test the vulnerability of trees to drought-induced xylem embolism, each with advantages and limitations. We quantified drought vulnerability using optical vulnerability and ultrasonic acoustic emission (UAE...

... and resistance in grafted plants, such as grapevine, remains unclear. This study evaluates the physiological responses, drought tolerance, hydraulic vulnerability segmentation, and xylem anatomy of 2-year-old Vitis vinifera cv. Tempranillo scion grafted onto two rootstocks: 110-Richter (110R...

The Scholander pressure chamber measures xylem tension by establishing a mechanical equilibrium between the atmosphere and a flat...

... beetles representing 6 species had viable spores. Nearly all (96%) spore-bearing beetles in both years were captured in late May or June. In bimonthly xylem samples collected from healthy trees, large earlywood vessels, presumably more vulnerable to infection than latewood, were present from May to June...
