AB Pseudomonas chlororaphis (Pc) representatives are found as part of therhizosphere-associated microbiome, and different rhizospheric Pc strainsfrequently perform beneficial activities for the plant. In this study wedescribed the interactions between the rhizospheric Pc strains PCL1601,PCL1606 and PCL1607 with a focus on their effects on root performance.Differences among the three rhizospheric Pc strains selected were firstobserved in phylogenetic studies and confirmed by genome analysis, whichshowed variation in the presence of genes related to antifungal compounds orsiderophore production, among others. Observation of the interactions amongthese strains under lab conditions revealed that PCL1606 has a betteradaptation to environments rich in nutrients, and forms biofilms. Interactionexperiments on plant roots confirmed the role of the different phenotypes intheir lifestyle. The PCL1606 strain was the best adapted to the habitat ofavocado roots, and PCL1607 was the least, and disappeared from the plantroot scenario after a few days of interaction. These results confirm that 2 out 3rhizospheric Pc strains were fully compatible (PCL1601 and PCL1606),efficiently colonizing avocado roots and showing biocontrol activity againstthe fungal pathogen Rosellinia necatrix. The third strain (PCL1607) hascolonizing abilities when it is alone on the root but displayed difficultiesunder the competition scenario, and did not cause deleterious effects on theother Pc competitors when they were present. These results suggest thatstrains PCL1601 and PCL1606 are very well adapted to the avocado rootenvironment and could constitute a basis for constructing a more complexbeneficial microbial synthetic community associated with avocado plant roots.
