Abstract

Fusarium species are cosmopolitan species that frequently isolated from soils and plant
debris and can seriously damaged plant, animal and human. Persian Gulf beaches in Iran
are the ideal habitat for a variety of Fusarium species. Therefore, the study is conducted
to gather some information on the population of Fusarium species which could be found
in Persian Gulf beaches in Iran. The study involved the isolation and identification of
Fusarium species from beach soil samples in Persian Gulf beaches. The direct isolation
technique from soil particles was used to isolate Fusarium species from beach soil
samples. Fusarium species were identified by the observation of macroscopic and
microscopic characteristics. Fusarium solani is the most common species found on the
beach samples which had the highest percentage of abundance (58%). The percentage of
abundance for other Fusarium species is relatively low, where F. proliferatum consists of
12%, followed by F. equiseti (10%), F. falciforme (10%), F. oxsysporum (7%) and F.
virguliforme (3%). Molecular identification using translation elongation factor 1α (tef1)
gene and nuclear ribosomal DNA internal transcribed spacer (ITS) sequences were
conducted to confirm morphological data. Numerous Fusarium species associated with
soil and different plants have been reported from Iran. Until today, there are no reports on
F. virguliforme in Iran. The study on the Fusarium species on beach soil samples of
Persian Gulf in Iran will provide insight on the influence of environment on occurrence of
Fusarium in Persian Gulf.
