Key Points

This research aims to explore how plants respond to bacterial quorum sensing molecules and the implications for disease resistance.
Identified bacterial QS molecules and their effects on plant responses.
Assessed coordination of plant immune responses upon QS signal detection.
Plants exhibited a preemptive disease resistance strategy upon detection of the bacterial QS molecule.

Implication

Experimental findings demonstrate that plants activate a disease resistance strategy upon detecting a bacterial QS signal, indicating a novel defense mechanism.

Abstract

. Our findings demonstrate that plants can translate the detection of a specific bacterial QS molecule into a coordinated, preemptive disease resistance strategy.
