Genomic information for bacteria within the genus  Rahnella  remains limited.  Rahnella  sp. JZ-GX1 was previously isolated from the  Pinus massoniana  rhizosphere in China and shows potential as a plant growth-promoting (PGP) bacterium. In the present work, we combined the GridION Nanopore ONT and Illumina sequencing platforms to obtain the complete genome sequence of strain JZ-GX1, and the application effects of the strain in natural field environment was assessed. The whole genome of  Rahnella  sp. JZ-GX1 comprised a single circular chromosome (5,472,828 bp, G + C content of 53.53%) with 4,483 protein-coding sequences, 22 rRNAs, and 77 tRNAs. Based on whole genome phylogenetic and average nucleotide identity (ANI) analysis, the JZ-GX1 strain was reidentified as  R. victoriana . Genes related to indole-3-acetic acid (IAA), phosphorus solubilization, nitrogen fixation, siderophores, acetoin, 1-aminocyclopropane-1-carboxylate (ACC) deaminase, gamma-aminobutyric acid (GABA) production, spermidine and volatile organic compounds (VOCs) biosynthesis were present in the genome of strain JZ-GX1. In addition, these functions were also confirmed by  in vitro  experiments. Importantly, compared to uninoculated control plants,  Pyrus serotina ,  Malus spectabilis ,  Populus euramericana  (Dode) Guinier cv. “San Martino” (I-72 poplar) and  Pinus elliottii  plants inoculated with strain JZ-GX1 showed increased heights and ground diameters. These findings improve our understanding of  R. victoriana  JZ-GX1 as a potential biofertilizer in agriculture.
