Insights into the structure and role of seed-borne bacteriome during maize germination

ABSTRACT Seed germination events modulate microbial community composition, which ultimately influences seed-to-seedling growth performance. Here, we evaluate the germinated maize (variety SHS 5050) root bacterial of disinfected seed (DS) and non-disinfected (NDS). Using a gnotobiotic system, sodium hypochlorite (1.25%; 30 min)-treated seeds showed reduction population size an apparent increase diversity associated with significant selective Burkholderia-related sequences. The shift in composition DS negatively affects speed, seedling reserve mobilization rates compared NDS. A synthetic (syncom) formed by 12 isolates (9 Burkholderia spp., 2 Bacillus 1 Staphylococcus sp.) obtained from natural microbiota herein was capable recovering when reintroduced DS. Overall, results that changes members' dominance interfere initial maize. By cultivation-dependent -independent approaches, deciphered seed–maize microbiome structure, niches location taxa relevant roles causal relationship between succession performance opens opportunities technologies to build-up communities boost plant health.
