Using the plant growth-promoting rhizobacteria (PGPR) Pseudomonas fluorescens 2P24 as a model, this study systematically deciphered the secretome of its T3SS. We demonstrate that T3SS in PGPR promotes the secretion of a niche-constructing enzymatic toolkit while actively suppressing the release of proteins conducive to a free-living state. Thus, this work redefines a classic virulence apparatus in mutualism and provides a mechanistic framework for engineering beneficial plant-microbe interactions.","dates":{"publication":"Fri Feb 13 00:00:00 GMT 2026"},"accession":"PXD074815","cross_references":{"TAXONOMY":["294"]}}
