Underground Explorers

This project aims to investigate the diversity of arbuscular mycorrhizal fungi (AMF) associated with African yam bean (Sphenostylis stenocarpa), an underutilised indigenous legume cultivated in southwestern Nigeria. Despite the ecological and nutritional importance of this crop, little is known about its associated mycorrhizal communities. Root and rhizosphere soil samples will be collected from smallholder farms across Ogun, Oyo, and Osun States. DNA will be extracted and subjected to PCR and sequencing to characterize AMF diversity and community composition. The resulting data will provide baseline information on fungal biodiversity in Nigerian agroecosystems and identify beneficial AMF that contribute to nutrient acquisition, soil fertility, and crop resilience. The findings will support sustainable agricultural practices by promoting the use of naturally occurring beneficial fungi as alternatives to synthetic fertilizers.
