Xylem-associated fungus can secrete many secondary metabolites to help Aquilaria trees resist various stresses and play a crucial role in facilitating agarwood formation. However, the dynamics of endophytic fungi sinensis xylem after artificial induction have not been fully elaborated. Endophytic communities physio-biochemical properties were examined before with an inorganic salt solution, including four different times (pre-induction (0M), third (3M), sixth (6M) ninth (9M) month treatment). The relationships between fungal diversity indices evaluated. results showed that superoxide dismutase (SOD) peroxidase (POD) activities, malondialdehyde (MDA) soluble sugar content first increased then decreased time, while starch was heavily consumed treatment. significantly lower treatment than before, but species richness promoted. Fungal β-diversity also clustered into groups according times. Core shifted from rare dominant taxa growing interactions network indicate gradual complication community structure. potential functions closely related physicochemical had less effect on relative abundance species. These findings assess regulatory mechanisms microorganisms expedite formation induction.
