Involvement of tRNA thiolation in uORF-mediated translational regulation during Xylogenesis in Arabidopsis thaliana.

Plant & cell physiology - 5 Sept 2026

Nishii Yuichi, Araki Daichi, Saraumi Mitsuru, Takahashi Taku

Abstract excerpt

Post-transcriptional modification of tRNAs is an important mechanism for regulating translation efficiency and cellular homeostasis, yet its contribution to upstream open reading frame (uORF)-mediated translational control remains largely unexplored. In this study, we investigated the role of tRNA thiolation in thermospermine-dependent regulation of xylem development in Arabidopsis thaliana. Using a suppressor...
