Thermospermine signaling in vascular development and stress adaptation: from translational regulation to climate-resilient crops.

Thermospermine acts as a bifunctional translational regulator essential for vascular development and stress adaptation in plants, influencing xylem differentiation and secondary growth.

• Why it matters: Understanding thermospermine's role fills a critical gap in knowledge about post-transcriptional regulation of vascular tissues and stress responses, which are vital for crop resilience amid climate change.
• What they did: The study reviews how thermospermine, synthesized by ACL5, promotes translation of specific transcription factors and modulates ribosomal activity, affecting plant vascular and stress responses across species.
• The result: Insights into thermospermine's regulatory functions enable strategies to engineer climate-resilient crops with optimized vascular systems and improved tolerance to abiotic stresses.
