Application of plant artificial cultivation substrates lead to alteration rhizosphere environment. Whether this could root microbiome variation was limitedly investigated. This work aims determine the diversity shifts in cucumber under different and predict corresponding function these bacterial microbiota. Cucumber samples cultivated with two greenhouse soils were prepared. Subsequently, high throughput sequencing bioinformatics analysis applicated compare their function. In total, 311,039 sequences obtained, they annotated 42 operational taxonomic units (OTUs), belonging 28 genera, 18 families, 12 orders, four classes, three phyla. The α β from significantly different. Only 2-3 species found be discrepancy between soils. relative abundance genus Asticcacaulis, Methylophilus, Massilia, Dyella, Devosia higher than that soils, while Phenylobacterium, Noviherbaspirillum, Arenimonas lower Besides, compared community synthetic pathways for flavonoids flavonols, bile acids, indole alkaloids, lactose, neolactose increased by 41.6-, 28.7-, 5.9-, 5.5-fold, respectively, substrate 1-cultivated roots, clavulanic acid, receptor interaction, sesquiterpenoid, flavonoid flavonol, alkaloid, 42.3-, 32.4-, 13.9-, 10.3-, 6.3-, 5.2-fold, two-cultivated roots. paper verified substrates. difference microbiota predicted. would provide theoretical support discovering microbial resources building flora.
