“…We hypothesized that specific, host immune sectors might be necessary for beneficial, growth-promoting activities of microbial root commensals. In the gnotobiotic FlowPot system ( 39 , 41 ), we recolonized germ-free A. thaliana Columbia-0 (Col-0, referred to as wild type [WT]) as well as a wide range of immunocompromised mutants with a synthetic multikingdom microbial community representative of naturally occurring root microbiomes (183 bacteria [B], 25 fungi [F], and 6 oomycetes [O]; BFO synthetic microbial community [SynCom], SI Appendix , Fig. S1 and Dataset S1 ) ( 3 ).…”

“…FlowPots were prepared as described before ( 39 , 41 ) with six FlowPots per microbox (SacO2, TD3000 + TPD3000, 3 L volume). Each FlowPot was repopulated with 200 µL bacterial, 200 µL fungal, and 80 µL oomycete pools, and each sterile FlowPot was mock inoculated with 480 µL 10 mM MgCl 2 (to account for the solution used to resuspend microbial cultures) and placed in light cabinets (Versatile Environmental Test Chamber MLR-352, Panasonic) with 10 h light (luminous flux per unit area inside the growth chamber average 9627.929, inside Microboxes average 6992.714).…”

“…In recent years, a reductionist approach to the synthetic community (SynCom) has been developed to study the specific mechanisms that drive community assembly and the interactions among different members in a gnotobiotic system [42] , [43] . For instance, the consistent differences between the maize phenotypes of inbred lines and hybrids and the composition of rhizosphere bacterial and fungal communities [44] have been further confirmed by inoculation with a simple community of seven bacterial strains [45] .This reductionist approach would allow global research to replicate experiments easily through two standardized pipelines: high-throughput bacterial cultivation and identification [46] , [47] and the establishment of plant growth systems [48] .…”

“…Associations between Arabidopsis and Pseudomonas species can serve as model systems to study plant-microbe interactions in the rhizosphere ( 9 11 ). Pseudomonas fluorescens and related species are widely plant-associated and are ubiquitously present in the rhizosphere microbiome.…”
