The third root exudation pathway: Glutamine that leaks from defects in the endodermis recruits and assembles bacteria

Key Points

• The commentary aims to explore how glutamine leakage from plant roots affects bacterial recruitment and assembly.
• Descriptive analysis of glutamine leakage from endodermis defects.
• Examination of bacterial chemotaxis in response to glutamine release.
• Discussion of the implications for plant-bacteria interactions.
• Glutamine leakage is shown to promote bacterial colonization in roots.
• Defects in the endodermis enhance bacterial recruitment via chemotactic responses.
• Bacterial proliferation occurs due to the combined effects of glutamine leakage and chemotaxis.
