Root endophytic microbiomes in resistant Manchurian ash (Fraxinus mandshurica) vs. susceptible Velvet ash (Fraxinus velutina) under emerald ash borer (Agrilus planipennis) infestation
Samples were collected from Xiongan New Area, Hebei Province (39.00 N, 116.04 E), China. Root tissues were sampled from Manchurian ash (Fraxinus mandshurica) and Velvet ash (Fraxinus velutina) inoculated with emerald ash borer (Agrilus planipennis) and uninoculated control trees. Distal fine roots (< 2 mm diameter) were collected at 50 cm soil depth using sterilized scissors. A total of 20 samples were obtained, with five biological replicates per treatment.
