Xylariales sp.  PMI_506 (1113385)

Xylariales sp. PMI_506 was isolated as an endophytic fungus from living roots of Populus deltoides1. A large number of Xylariales species occur as endophytes in association with plants in temperate and tropical forests, with many novel species continuously being described. Some members of this group also cause disease on tree seedlings2. Endophytic Xylariales species have been characterized as potential sources of novel metabolites that can be bioactive compounds of potential use in drug industry3. Based on ITS sequence, PMI_506 is distinct from other Xylariales, and additional taxonomic study is still needed to evaluate this species.
