The fungus Acremonium alternatum enhances salt stress tolerance by regulating host redox homeostasis and phytohormone signaling

open access: yesPhysiologia Plantarum, Volume 176, Issue 3, May/June 2024.
Abstract While endophytic fungi offer promising avenues for bolstering plant resilience against abiotic stressors, the molecular mechanisms behind this biofortification remain largely unknown. This study employed a multifaceted approach, combining plant physiology, proteomic, metabolomic, and targeted hormonal analyses to illuminate the early response ...

ReSurveyEurope: A database of resurveyed vegetation plots in Europe

open access: yesJournal of Vegetation Science, Volume 35, Issue 2, March/April 2024.
We introduce ReSurveyEurope – a new data source of 79,190 resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We describe the scope of this initiative, provide an overview of currently available data, governance, data contribution rules, and accessibility. In addition, we outline further steps, including

Longer‐Term Outcomes of the Yacoub versus Bentall Procedure in a Nationwide Propensity‐Matched Comparison

open access: yesJournal of Cardiac Surgery, Volume 2024, Issue 1, 2024.
Background. Aortic root replacement with a composite mechanical valve graft (Bentall procedure) has been a recommended strategy in patients with aortic root aneurysm with or without aortic regurgitation. Aortic root remodeling (Yacoub procedure) has emerged as a valve‐sparing alternative although there is only scarce multicenter evidence.

Spatially balanced subsampling improves stand-level leaf area index estimation in mature Norway spruce stands

open access: yesFrontiers in Forests and Global Change
IntroductionLeaf area index (LAI) estimation is sensitive to sensor field of view (FOV), within-plot spatial heterogeneity, and sampling layout. Because LAI influences canopy radiation transmission, microclimate and vegetation–atmosphere exchange, robust
