Fungal endophytes limit pathogen damage in a tropical tree
... Antipathogen Assays. To generate endophyte-free seedlings of T. cacao, we collected seeds from healthy, mature fruit borne on 10 randomly chosen trees at BT. Before planting in sterile soil, seeds were washed in 0.5% sodium hypochlorite (3 min) to limit viability of surface-borne fungi, and were ran ...
