First report of Onion yellow dwarf virus infecting onion in Ecuador.

Abstract:

In July 2015, onions with irregular yellow striping, downward leaf curling, and plant stunting were observed in the Tungurahua province of Ecuador. Symptomatic (n= 10) and healthy onion samples were screened by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) with OYDV polyclonal antibodies. Based on the results of DAS-ELISA tests, PCR assay and BLAST and phylogenetic analyses of the nucleotide sequences, the causal agent was identified as Onion yellow dwarf virus (OYDV). This is thought to be the first report of OYDV on onion in Ecuador.
