Subversion of plant endomembrane trafficking by a Plasmodiophora brassicae effector PbALE that recruits membrane components at the host–pathogen interface to aid in colonization

New Phytologist, Volume 252, Issue 5, Page 2006-2023, December 2026.
Schematics of ΔSPPbALE‐induced disruption of plant endomembrane trafficking impairs both preinvasive and postinvasive immunity against filamentous fungi and facilitates intracellular colonization by Plasmodiophora brassicae. Summary Plasmodiophora brassicae, an intracellular biotrophic protist that causes clubroot in crucifers, extensively alters the ...

Dual mechanisms give rise to biphasic stomatal opening in onion

New Phytologist, Volume 252, Issue 5, Page 1976-1987, December 2026.
Anisotropic guard cell wall stiffness enhances onion stomatal pore opening by increasing guard cell arc length. Summary Stomata are controllable micropores on the leaf surface that regulate gas exchange and water loss. Pore aperture adjustment is a mechanical process whereby changes in guard cell turgor drive changes in cell shape, resulting in ...

Reporting treatment planning, delivery, and dose evaluation for 3‐dimensional MLC‐based SFRT: A single institutional clinical experience

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Purpose/Objective We report our institutional clinical experience of treatment planning, dose evaluation, and delivery via the same‐day 3D MLC‐based crossfire method for spatially fractionated radiotherapy (SFRT) in conjunction with combination therapy. Additionally, we aimed to model our clinical outcome data to provide clinical insights into

Daily Multi‐Leaf Collimator positional error prediction using machine learning: A Dynalog‐based approach for patient specific quality assurance

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Accurate positioning of multi‐leaf collimators (MLCs) is critical for ensuring the dosimetric precision of intensity‐modulated radiation therapy (IMRT). Nonetheless, daily MLC positional variations can degrade treatment accuracy, emphasizing the need for robust methodologies to detect and predict these deviations. Purpose This study
