XadA-like adhesin XADA2 regulates biofilm formation in X. fastidiosa subsp. fastidiosa putatively by engaging oleic-acid derived oxylipins.

ABSTRACT:

Background

The oxylipins 10-HpOME and 7,10-DiHoME derive from oleic acid and have been extensively studied for their ability to regulate contractions, microcolony formation and biofilm formation in the model organism Pseudomonas aeruginosa.

Methods and results

Xylella fastidiosa subsp. pauca strain de Donno has been reported to produce 10-HpOME and 7,10-DiHOME in vivo when inoculated in the model plant Nicotiana tabacum or in naturally occurring infected olive trees. In this study, we deciphered the relationship among cell adhesion and oxylipins in Xylella fastidiosa subsp. fastidiosa (Temecula1 strain) and subsp. multiplex (AlmaEM3 strain). The role of the PD0744 gene, encoding for XadA2, a non-fimbrial adhesin belonging to the trimeric autotransporter family, probably invo
