Altered bacteria community dominance reduces tolerance to resident fungus and seed to seedling growth performance in maize (Zea mays L. var. DKB 177)

• Seed-borne bacteria is an essential source of the plant microbiome. Maize seed germination modulates ecological succession for seed-borne microbiota. Seed-bacteriome abundance taxa in germinated maize seeds. influence and growth maize. Seed microbiome acts as a “bacterial barrier” against phytopathogens. seed-bacteria community var DKB177 protect Penicillium sp. fungus. Seeds are reservoirs beneficial harmful microorganism that health. Here, we access to seedling bacteriome assembly modified by seed-disinfection underlined effect over performance root-seedlings microbial colonization. Seed-disinfection was performed with sodium hypochlorite (1.25 %, 30 min), resulting reduction cultivable-dependent fraction population, but not significantly detected real-time PCR, microscopy, biochemical analysis roots on 16S rRNA sequencing revealed non-germinated seeds 5-d exhibited similar diversity did differ structure concerning seed-disinfection. On other hand, relative genera f_Enterobacteriaceae_922761 (unassigned genus), Azospirillum, Acinetobacter disinfected-seed prior seems display changes prominence several new Interestingly, this rebuilt negatively affected speed plantlets. Additionally, re-shape increased var. DKB 177 susceptible pathogen Such natural composition removed barrier, increasing susceptibility pathogens, impairing disinfected germinate, develop.
