Description Decades of plant breeding have achieved huge success in controlling Fusarium wilt with resistant cultivars, while the interactions between these cultivars and rhizosphere microorganism are still elusive. Here, two phenotypes of cucumber, one resistant and one with increased susceptibility to Fusarium oxysporum f.sp. cucumerinum (Foc) were grown in soil and hydroponics, 16S rRNA sequencing and non-targeted metabolomics technologies were used to investigate rhizosphere microflora and root exudation profiles. Lower microbial community evenness of the Foc-resistant cultivar was found and the relative abundances of Comamonadaceae and Xanthomonadaceae were higher in the Foc-susceptible cultivar. FishTaco analyses revealed specific functional traits such as protein synthesis and secretion, bacterial chemotaxis and small organic acid metabolism pathways were significantly less abundant in the Foc-resistant cultivar rhizobacterial community.
