This finding reveals how plants use chemical signals to shape their root microbiome for better health and deciphers its links to Casparian strip integrity.

Abstract

This commentary on Tsai et al. (2025) highlights glutamine's important role in attracting beneficial bacteria to colonize plant roots, deciphers its links to Casparian strip integrity, and explores its dual functions. This finding reveals how plants use chemical signals to shape their root microbiome for better health.
