Pectin-derived oligogalacturonides shape mutualistic interactions between Bacillus and its host plant.

ABSTRACT: Certain beneficial bacteria of the root-associated microbiome such as Bacillus velezensis protect plants against diseases and are promising biocontrol agents exploited in sustainable agriculture. Unveiling the molecular dialogue governing mutualistic interactions between these beneficials and their host is essential to better understand their ecological behavior and to optimize their use as bioprotectants. However, the chemical diversity and functionality of mediators involved in this interkingdom crosstalk remain largely unexplored. In this study, we uncover a strategy by which B. velezensis exploits the root cell wall polymer pectin to prime its host for enhanced resistance against phytopathogens and to ensure a safe environment enabling its efficient root establishment.
