AB The rhizobacterium Pseudomonas alcaligenes AVO110 exhibits antagonism toward thephytopathogenic fungus Rosellinia necatrix. This strain efficiently colonizes R. necatrix hyphae andis able to feed on their exudates. Here, we report the complete genome sequence of P. alcaligenesAVO110. The phylogeny of all available P. alcaligenes genomes separates environmental isolates,including AVO110, from those obtained from infected human blood and oyster tissues, which clustertogether with Pseudomonas otitidis. Core and pan-genome analyses showed that P. alcaligenes strainsencode highly heterogenic gene pools, with the AVO110 genome encoding the largest and mostexclusive variable region (~1.6 Mb, 1795 genes). The AVO110 singletons include a wide repertoire ofgenes related to biofilm formation, several of which are transcriptionally modulated by R. necatrixexudates. One of these genes (cmpA) encodes a GGDEF/EAL domain protein specific to Pseudomonasspp. strains isolated primarily from the rhizosphere of diverse plants, but also from soil and watersamples. We also show that CmpA has a role in biofilm formation and that the integrity of itsEAL domain is involved in this function. This study contributes to a better understanding of theniche-specific adaptations and lifestyles of P. alcaligenes, including the mycophagous behavior ofstrain AVO110
