Endophytes of industrial hemp (Cannabis sativa L.) cultivars: identification of culturable bacteria and fungi in leaves, petioles, and seeds.

abstract：:A transformation protocol mediated by Agrobacterium tumefaciens is described for the sapstaining fungus Ophiostoma piceae. We compared transformants obtained from Agrobacterium with those obtained from yeast-like cells made into spheroplasts and treated with CaCl2. For all putative transformants analyzed, Southern hyb...
