The white-line-in-agar test is not specific for the two cultivated mushroom associated pseudomonads, Pseudomonas tolaasii and Pseudomonas “reactans”

SummaryA sharply defined white line in vitro forms between the pathogenic form of Pseudomonas tolaasii and another Pseudomonas bacterium, referred to as “reactans”. This interaction has been considered as highly specific. However, results presented in this study rise doubt about the strict specificity of this interaction, as some other pseudomonads, associated with the cultivated mushroom Agaricus bisporus, also yielded a white line precipitate when they were streaked towards Pseudomonas tolaasii LMG 2342T. Moreover, some Finnish isolates inducing brown blotch symptoms on mushrooms like P. tolaasiiT, produced a typical white precipitate when streaked towards P. “reactans” LMG 5329, even though phenotypical and genotypical features exclude these isolates from the species P. tolaasii. We propose that the white-line-in-agar (WLA) test should no longer be considered as an unequivocal diagnostic trait of P. tolaasii.
