Genetic dissection of the root system architecture QTLome and its relationship with early shoot development, breeding and adaptation in durum wheat

open access: yesThe Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Root system architecture (RSA), shoot architecture, and shoot‐to‐root biomass allocation are critical for optimizing crop water and nutrient capture and ultimately grain yield. Nevertheless, only a few studies adequately dissected the genetic basis of RSA and its relationship to shoot development.

A network-based approach to identify substrate classes of bacterial glycosyltransferases [PDF]

open access: yes, 2014
Background: Bacterial interactions with the environment-and/or host largely depend on the bacterial glycome. The specificities of a bacterial glycome are largely determined by glycosyltransferases (GTs), the enzymes involved in transferring sugar ...

The Influence of Lipopolysaccharide O‐Antigen Chain Length on Biofilm Formation Capacity and Outer Membrane Proteome Shape of Salmonella Enteritidis

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Shortening of the LPS O‐antigen part is related to decreased biofilm biomass formation, which also depends on the composition of the culture medium. Physicochemical properties of bacterial cells changed with the shortening of the O‐antigen, promoting bacterial aggregation, hydrodynamic size, zeta potential, and hydrophobicity.

RNA aptamers to the peptidyl transferase inhibitor chloramphenicol

open access: yesChemistry & Biology, 1997
The problem of how macromolecules adopt specific shapes to recognize small molecules in their environment is readily addressed through in vitro selections (the SELEX protocol). RNA-antibiotic interactions are particularly attractive systems for study because they provide an opportunity to expand our understanding of molecular recognition by RNA and to ...

miR‐140‐5p Overexpression Contributes to Oxidative Stress and Mitochondrial Dysfunction in Hutchinson‐Gilford Progeria Syndrome Fibroblasts Through NRF2 Pathway

open access: yesAging Cell, Volume 24, Issue 12, December 2025.
This study identifies a novel molecular mechanism involving miR‐140‐5p that contributes to the pathogenesis of HGPS. By decreasing NRF2 expression, miR‐140‐5p overexpression results in downregulation of the NRF2/KEAP1/HO‐1 antioxidant pathway in HGPS fibroblasts, leading to increased oxidative stress and mitochondrial dysfunction, two hallmarks of ...

Die molekulare Logik der nichtribosomalen Peptidsynthetasen: Identifizierung und biochemische Charakterisierung der Biosynthesegene für Gramicidin A [PDF]

open access: yes, 2005
Gramicidin ist ein Polypeptid, das aus 15 hydrophoben Aminosäuren mit alternierender L-D-Konfiguration besteht. In vivo bilden sich Homodimere, die in Membranen als Ionenkanäle fungieren.
