dc.description.abstractAims: The aim of this study was to identify the best combination of plant growth promoting bacteria (PGPB) and arbuscular mycorrhizal fungi (AMF) for biofortification and enhancing yield in wheat as well as improve soil health under field conditions. Another aim was to get insights into metabolite dynamics in plants treated with PGPB and AMF. Methods and Results: Different combinations of PGPB and AMF that gave good results in greenhouse study were used in a field study. The combined application of Bacillus subtilis CP4 (native PGPB) and AMF gave the best results with a significant increase in biomass, macronutrient and micronutrient content in wheat grains and improvement in yield-related parameters relative to the untreated control. PGPB and AMF treatment increased antioxidant enzymes and compounds and decreased the level of an oxidation marker. Metabolite profiling performed using Gas Chromatography�Mass Spectrometry (GC-MS) showed significant upregulation of specific organic acids, amino acids, sugars and sugar alcohols in plants treated with CP4 and AMF. The altered pathways due to CP4 and AMF inoculation mainly belong to carbohydrate and amino acid metabolism. A positive correlation was observed between some organic acids, sugars and amino acids with wheat growth and yield parameters. The activities of soil enzymes increased significantly with the best results shown by native PGPB and AMF combination. Conclusions: A native bacterial isolate Bacillus subtilis CP4 in combination with AMF showed exceptional ability for biofortification and yield enhancement under field conditions. The upregulation of a number of metabolites showed correlation plant growth promotion and nutrients. Significance and Impact of the Study: The combined application of native B. subtilis CP4 and AMF could offer a more sustainable approach for the development of a biofertilizer to enhance wheat nutrient content and production and soil health thereby advancing agriculture. � 2020 The Society for Applied Microbiologyen_US
