Dressing like a pathogen: Comparative analysis of different Pseudomonas genomospecies wearing different features to infect Corylus avellana

During the last decade, European hazelnut (Corylus avellana) has been threatened by several bacterial and fungal infections. In particular, at least four different Pseudomonas species have developed capability to converge into same host. However, one of these species, avellanae, may infect other hosts as well. Here, we newly provide complete genome sequence two avellanae strains obtained a combination long Oxford Nanopore Technologies reads (ONT) short Illumina reads. These included in comparative analysis with all genomes known Corylus avellana available on NCBI database, infecting host plants, like Prunus, Actinidia from river epilithon. The clustered according their taxonomy, geographic origins. identification specific traits related each population cluster could give us insights regarding host–pathogen interaction range specificity. Indeed, peculiar set three type III secretion effectors, while Prunus are carrying genomic WHOP island, necessary for woody-host infection. syringae cluster, instead, contains more phytotoxins, ice nucleation but less effectors. Thus, here, confirmed that convergence was possible due unrelated mechanisms
