Turnip mosaic virus utilizes the lipid droplet biogenesis machinery to facilitate its propagation in plants

New Phytologist, EarlyView.
Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions, including membrane remodeling during abiotic stress.

The role of clathrin in post‐Golgi secretion in plant cells

New Phytologist, EarlyView.
Morphology of Arabidopsis thaliana XVE»amiCHC seedlings. Summary Within the plant endomembrane system, the vesicle coat protein clathrin localizes to the plasma membrane (PM) and the trans‐Golgi Network/early endosome (TGN/EE). While the role of clathrin in endocytosis at the PM is well established, its function at TGN/EE, presumably in late secretion (

Ventricular Synchrony in Targeted Right Ventricular Septal Pacing: A Prospective Paired Comparison to Apical Placement

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background/Objectives Right ventricular (RV) apical pacing, the standard pacing approach, often induces ventricular dyssynchrony, potentially impairing cardiac function. This study aims to investigate whether targeted RV septal pacing, guided by functional electrophysiological feedback during implantation, reduces ventricular dyssynchrony ...

Targeted Modulation of Eukaryotic Release Factor 1 (OseRF1) by an RNA Aptamer Enhances Drought Adaptation in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Drought stress severely restricts rice productivity, necessitating strategies to enhance stress resilience. Here, we identify translation termination as a tunable regulatory node for stress adaptation. Using 25 rounds of SELEX, we isolated RTAR, an RNA aptamer that binds the rice eukaryotic release factor 1 (OseRF1) with nanomolar affinity ...

RNA‐Guided Engineering of the Chloroplast Genome Enabled by Plastid‐Expressed Guide RNAs

Plant Biotechnology Journal, EarlyView.
ABSTRACT Our goal is to develop RNA‐guided engineering of the chloroplast genome using the CRISPR/Cas9 system. We designed chloroplast minigenes to obtain properly sized single guide RNAs (sgRNAs) in tobacco chloroplasts. The sgRNA 5′ end is defined by transcription from an rRNA operon promoter, and its 3′ end by processing a downstream tRNA (trnG) or ...

Loss of DET1 in High Pigment 2 Tomato Prevents High Temperature Repression of Anthocyanin Biosynthesis in Fruit Through HY5 Stabilization

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming impacts several aspects of plant physiology, with important negative effects on crop yield and production of secondary metabolites, such as anthocyanins. The anthocyanin content of vegetables and fruits has attracted public interest in the last two decades due to its health benefits, leading to the development of novel ...

What Does “STEM” Mean to Students? Exploring the Interplay Between Self‐Efficacy, Extracurricular Activities, Subject Associations, and Academic Intentions in Secondary School

School Science and Mathematics, EarlyView.
ABSTRACT Despite extensive discourse in educational research and practice, inconsistencies persist in students' perception of, and engagement with, STEM subjects. This study investigates how secondary school students perceive STEM disciplines, and which factors modulate their self‐efficacy and academic intentions. The survey (n = 853) revealed a widely
