Esherichia coli O157:H7 F9 fimbriae recognize plant xyloglucan and elicit a response in Arabidopsis thaliana
Ontology highlight
ABSTRACT: Fresh produce are often a source of enterohaemorrhagic Escherichia coli (EHEC) outbreaks. Fimbriae are extracellular structures involved in cell-to-cell attachment and surface colonisation. F9 (fml) fimbriae have been shown to be expressed at temperatures lower than 37°C, implying a function outwith the mammalian host. As fimbriae are multimeric structures with a molecular pattern, we investigated whether F9 fimbriae could induce a transcriptional response in model plant Arabidopsis thaliana, compared to flagella (H7) and another fimbrial type (Mat3), using DNA microarrays. F9 induced the differential expression of 435 genes, including genes involved in the plant defence response.
