Two-faced OsNAS3 influences disease resistance via nicotianamine and ethylene

J Integr Plant Biol. 2024 Dec;66(12):2581-2585. doi: 10.1111/jipb.13788. Epub 2024 Oct 23.

Abstract

The loss and gain of OsNAS3 function both positively influence plant disease resistance. Overexpression of OsNAS3 boosts blast resistance by promoting nicotianamine accumulation, thereby enhancing blast resistance. Conversely, knockout of OsNAS3 increases ethylene biosynthesis, also contributing to improved blast resistance.
