Abstract Background The rhizosphere is the narrow zone of soil immediately surrounding root, and it a critical hotspot microbial activity, strongly influencing physiology development plants. For analyzing relationship between microbiome metabolome in tea ( Camellia sinensis ) plants, bacterial composition its correlation to metabolites were investigated under three different fertilization treatments (unfertilized, urea, cow manure) growing seasons (spring, early late summer). Results phyla Proteobacteria , Bacteroidetes Acidobacteria Actinobacteria dominated plants regardless sampling time. These indicated that compositional shift was associated with fertilizer/manure as well However, relative abundance these enriched bacteria varied fertilizer regimes. Most metabolic pathways stimulated by application all related sugars, amino acids fatty alkaloids metabolism. Organic potential mediating plant-bacteria interaction rhizosphere. Bacteria genera Proteiniphilum Fermentimonas Pseudomonas spring, Saccharimonadales Gaiellales summer, Acidobacteriales summer regulated contents organic acids. Conclusion This study documents profound changes bacterially derived regimes provides conceptual framework towards improving performance plantations.
