Description
Summary:[Display omitted] •ZnONRs are not effective antimicrobial agents against P. syringae.•Some pathovars of P. syringae are highly resistant to ZnONRs with tiny sizes.•Biofilm formation contributes to evaluating the virulence and fitness of P. syringae. The P. syringae bacteria is one of the most relevant pathogens for agriculture due to the large number of agricultural species it infects. At this point, the formation of biofilms contributes to determining its virulence and fitness. In agriculture, the ZnO nanoparticles are recognized for their potential use as nanofertilizers and antimicrobial compounds. In this sense, this work aimed to study the effect of ZnO nanorods (ZnONRs) on biofilms and in the planktonic state of different pathovars of the plant pathogen P. syringae. In contrast with the literature, our results showed that the tested pathovars are highly resistant to shaped-rod ZnO with tiny sizes because they showed no inhibitory effect in mature biofilms exposed to high concentrations of up to 500 µg/mL of nanoparticles.
