XND1-centered network regulates salt tolerance by integrating root xylem plasticity and Na+ unloading in Arabidopsis

Proceedings of the National Academy of Sciences, Volume 122, Issue 43, October 2025. <br/>SignificanceAlthough xylem is the primary conduit for long-distance transport in plants, its potential role in regulating ion homeostasis and salt tolerance has remained largely unexplored. Here, we demonstrate that the transcription factor XND1 (Xylem …
