Antimicrobial activity of fungal endophytes from Vaccinium dunalianum var. urophyllum

Fungi associated with Vaccinium species play important roles in plant growth and disease control, especially in the final blueberry production. Vaccinium dunalianum var. urophyllum (Ericaceae) is a well-known medicinal plant in Southern China used to treat inflammation and microbial infections. The...
