Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions. [PDF]
Environ Microbiol RepSoil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

A Method to Visualize Cell Proliferation of <i>Arabidopsis thaliana</i>: A Case Study of the Root Apical Meristem. [PDF]
Plant DirectABSTRACT Plant growth and development rely on a delicate balance between cell proliferation and cell differentiation. The root apical meristem (RAM) of Arabidopsis thaliana is an excellent model to study the cell cycle due to the coordinated relationship between nucleus shape and cell size at each stage, allowing for precise estimation of the cell ...

Meta‐analysis of genome‐wide DNA methylation and integrative omics of age in human skeletal muscle
Journal of Cachexia, Sarcopenia and Muscle, Volume 12, Issue 4, Page 1064-1078, August 2021., 2021 Abstract Background Knowledge of age‐related DNA methylation changes in skeletal muscle is limited, yet this tissue is severely affected by ageing in humans. Methods We conducted a large‐scale epigenome‐wide association study meta‐analysis of age in human skeletal muscle from 10 studies (total n = 908 muscle methylomes from men and women aged 18–89 ...
