<i>Pseudomonas boreofloridensis</i> sp. nov., and <i>Pseudomonas citrulli</i> sp. nov., isolated from watermelon in Florida.

ABSTRACT: Three fluorescent bacterial strains, K1, K13 and K18, were obtained from watermelon (Citrullus lanatus) foliage symptomatic of bacterial leaf spot of cucurbits in Florida. The strains underwent phenotypic characterization, including LOPAT (levan production, oxidase activity, pectolytic activity on potato, arginine dihydrolase production and hypersensitive response (HR) on both tobacco and tomato) and pathogenicity testing on watermelon and squash seedlings. Whole-genome sequencing of the isolates was performed, and multi-locus sequence analysis (MLSA) utilizing housekeeping genes gltA, rpoD, gapA and gyrB placed the isolates into two distinct clades within the Pseudomonas genus. Average nucleotide identity based on blast (ANIb) was used to compare
