RNA sequencing of fungal-fermented soybean

Flavonoids are an important class of plant specialized metabolites. They have various biological functions, including antioxidant action and interaction with other organisms. For example, daidzein and genistein are required for symbiosis with rhizobia, and daidzein is a precursor of glyceollin. Previous studies showed that isoflavonoids were increased by the inoculation of fungi in soybean. However, transcriptomic and metabolomic change by fungal inoculation has not yet been investigated. In this study, we investigated the metabolic response of fungal-fermented soybean seedlings at the transcriptome and metabolome levels.
