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

Plant Biotechnology Journal, Volume 24, Issue 10, Page 5440-5459, October 2026.
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 ...

Performance of Blind Turbo Equalizer in Indoor Channels

Journal of Communications Software and Systems, 2011
In this paper, we consider the transmission of turbo coded symbols in the indoor radio environment. The system isaffected by the intersymbol interference (ISI) caused by the multipath time-delay spread of the transmission medium.
