Proprioception drives tension wood formation for autotropic straightening and postural control in trees

open access: yesNew Phytologist, EarlyView.
Proprioception controls trunk straightness in trees through opposite tension wood formation. A spherical growth chamber (a), combined with a two‐dimensional rotating clinostat (b2), suppresses gravi‐ and phototropic sensing. The tree is first tilted horizontally (b1), triggering upward gravitropic bending, actuated by tension wood formation on the ...

Navigating Digital Transformation? The Guiding Role and Socialization Processes of Change Agents

open access: yesPublic Administration, EarlyView.
ABSTRACT This article investigates the role of internal change agents in advancing digital transformation within public sector organizations. In response to the complexities of digitalization, these change agents guide their peers in adopting technology and bridging the gap between strategy and implementation. We draw on an 18‐month diary study (N = 68,

Cytokinins Promote Rust Susceptibility in Poplar by Suppressing Defence Signalling, Reducing Defence Accumulation and Reprogramming Primary Metabolism

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Cytokinins (CKs), classically recognised as plant growth regulators, are increasingly implicated in plant‐microbe interactions. Studies in herbaceous plants suggest that CKs can function as signalling molecules with dual roles in plant defence, either restricting or facilitating pathogen infection.

30 years of enamel matrix derivative: Mimicking tooth development as a clinical concept

open access: yesPeriodontology 2000, EarlyView.
Abstract The use of growth factors (GFs) has become a cornerstone of modern regenerative periodontology. While the extent to which GFs enhance tissue regeneration compared to other biomaterials was initially uncertain, it is now well established that GFs play a critical role in the regeneration of various tissue types.
