Abstract

Xylella fastidiosa is the causal agent of important crop diseases and is transmitted by xylem-sap-feeding insects. The bacterium colonizes xylem vessels and can persist with a commensal or pathogen lifestyle in more than 500 plant species. In the past decade, reports of X. fastidiosa across the globe have dramatically increased its known occurrence. This raises important questions: How does X. fastidiosa interact with the different host plants? How does the bacterium interact with the plant immune system? How does it influence the host's microbiome? We discuss recent strain genetic typing and plant transcriptome and microbiome analyses, which have advanced our understanding of factors that are important for X. fastidiosa plant infection.

Keywords: EFR; host adaptation; microbiome; pattern recognition receptor (PRR); plant immunity; vascular pathogen; xylem.
