 Abstract: Most plant species are associated with a plethora of bacterial species with some of them being pathogenic. Recent studies indicate that specialized metabolites - small molecule products of metabolism that are not essential for survival - produced by the pathogen play a role in colonization and pathogenicity. These compounds are used for interacting with the environment, for example they can influence microbe-microbe interactions or even host-microbe interactions. The genomic regions responsible for the production of these metabolites are called biosynthetic gene clusters (BGCs). Here we aim to show that the presence or absence of these BGCs can potentially predict successful colonization and pathogenicity of a microbe. Using bioinformatic tools we have predicted syntenic biosynthetic clusters (BGCs) in 94 different strains of the most common bacterial pathogen of Arabidopsis thaliana, Pseudomonas virdiflava. We used genome wide association mapping to identify novel BGCs associated with pathogenicity and validated the top candidates for their involvement in causing disease. Our results support a significant role of BGCs in strain-level pathogenicity variation and a pipeline for identifying novel candidates.
