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 ...

PERFORMANCE OF TURBO CODED SIGNALS OVER FADING CHANNELS

Electrica, 2019
In this paper, the performance of turbo coded signals are investigated for different frame numbers and encoder structures over Rician fading channels. The numerical results demonstrate the error performance degradation due to fading channel frame numbers

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

Ovarian hormone loss modifies the nucleic acid cargo of circulating extracellular vesicles and skeletal muscle metabolism after acute exercise in rats

Experimental Physiology, EarlyView.
Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.

The Performance of Turbo Coded Orthogonal Frequency Division Multiplexing System over Flat Rayleigh Fading Channel

Journal of Engineering and Sustainable Development, 2009
This work investigates the effectiveness of Turbo Codes and Orthogonal Frequency Division Multiplexing (OFDM) system, for communication over the flat Rayleigh fading additive white Gaussian noise (AWGN) channel. The Fast Fourier Transform (FFT) is used

The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

The Journal of Physiology, EarlyView.
Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained

Gq Signaling in Microglia Triggers Interferon Responses and Improves Outcome After Ischemic Stroke

Glia, Volume 74, Issue 10, October 2026.
Chemogenetic activation of Gq signaling in microglia ahead of ischemic stroke reduces infarct size in mice. Seven days after stroke, Gq‐primed microglia in the penumbra show enhanced interferon responses, altered branching patterns, and reduced phagocytosis.
