Endophytic fungi could be associated with superior qualities and abiotic stress resistance including polycyclic aromatic hydrocarbons contaminations in the host plant. However there is lack of enough information on the effect of endophytic fungi in hydrocarbon contaminated soils. In order to know the effects of these endophytes, the air-dried soil samples of two point of Shadegan wetland in the Northwest of Persian Golf were contaminated with Naphthaline, Chrysene, and Naphthaline-chrysene in approximately 150 mg/kg. Both E+ and E- plants of each genotype were planted in the contaminated soils. The results showed that soil of pots containing endophyte-infected plants had less Naphtalen and Chresene. It seems that endophytic fungi could enhance root exudates and biomass of plants and this may promote degredation and elimination of contaminants. Plants harboring endophytic fungi could be used for phytoremediation of hydrocarbons contaminated soils.
