Complete Genome Resource for <i>Pseudomonas</i> sp. Strain WP18 Isolated from a Disease-Suppressive Soil

Bacterial strain WP18 was isolated in the Mississippi Delta from the rhizosphere of a healthy soybean plant growing in a charcoal rot disease patch, caused by the fungal pathogen Macrophomina phaseolina. The 16S rDNA sequence analysis demonstrated that the strain belongs to the genus Pseudomonas. Preliminary studies show that strain WP18 possesses antimicrobial activity against known plant pathogens. Pseudomonas sp. strain WP18 was found to have a single, circular chromosome that is 6,336,986 base pairs in size. No plasmids were detected. There are a total of 5,669 coding genes in the WP18 genome, including 5,533 putative protein-coding genes, 50 putative pseudogenes, 82 genes encoding RNAs (16 rRNAs and 66 tRNAs), and a non-coding RNA. The WP18 genome has two predicted gene clusters that may encode the antimicrobial compounds hydrogen cyanide and 2,4-diacetylphloroglucinol. However, the essential genes for the production of phenazines, the Pseudomonas type III secretion system, and phytotoxins were not found. The findings of this study provide a genome resource for the bacterium. [Formula: see text] Copyright © 2025 The Author(s).
