Trichoderma asperellum promotes cadmium accumulation within maize seedlings

Cadmium (Cd) is one of the most toxic heavy metal pollutants known to accumulate in the soil environment and pose a threat to public health. The tolerance of endophytic fungi isolated from Kosteletzkya virginica to cadmium was determined by the Oxford cup method. Trichoderma asperellum displayed the...
