Conteúdo: | The rhizosphere microbiome plays a key role in plant growth and health, providing a first line of defense against pathogen root infection. Here, we investigated how breeding for resistance of common bean (Phaseolus vulgaris) to the soil borne pathogen Fusarium oxysporum (Fox) changes the composition and metabolic potential of the bacterial community in the rhizosphere. For different bean cultivars grown in two contrasting soils, rhizobacterial abundance was positively correlated with Fox-resistance. Pseudomonadaceae, Bacillaceae, Solibacteraceae and Cytophagaceae are more abundant in the rhizosphere of the resistant cultivar. Network analyses showed a non modular topology of the rhizosphere microbiome of the Fox-resistant cultivar, suggesting a more complex and highly connected bacterial community when compared to the Fox-susceptible cultivar.
