The KoNF‐YC1‐KoXTH5 Regulatory Module Enhances Salt Tolerance by Cell Wall Remodeling and Ion Homeostasis in Mangrove Kandelia Obovata

Summary statement We identified 20 XTHs from mangrove kandelia obovata , with KoXTH5 being salt‐inducible. Overexpression in Arabidopsis enhanced salt tolerance by cell wall remodeling and ion homeostasis, and transcription factor KoNF‐YC1 directly activates KoXTH5, revealing a cell wall‐mediated adaptation mechanism.
