Onion (Allium cepa L.) is one of the most important vegetable crops in
Serbia, where it is grown on an approximate surface of 20,000 ha. During the
routine quality control analysis of onion seed in 2014, fungal infection was
observed in an average of 28% of the seed. The objective of this paper was to
isolate, determine, and identify Fusarium sp. based on the pathogen’s
morphological and molecular characteristics. Onion seed samples were
collected from different localities in the region of Vojvodina. To obtain a
DNA sequence-based identification, a total DNA of the 25 isolates was
extracted directly from the mycelium (~ 100 mg wet weight), with a DNeasy
Plant Mini Kit (Qiagen, Hilden, Germany). Following DNA extraction, the
translation elongation factor 1-alpha region was amplified by PCR with the
primer pair EF1 and EF2. An amplicon of 700 bp was amplified in 25 tested
isolates. Identification of one isolate was performed by sequencing the
translation elongation factor EF-1α gene, which was deposited in the NCBI
GenBank database under accession number KP658211 (Fusarium sp. FIESC3).
