VELARDE-FELIX, Sixto et al. First incidence of yellow vein virus of huasteco pepper in soybean in Mexico. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.7, pp.1389-1398.  Epub Sep 30, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i7.683.

In the state of Sinaloa, soybeans are one of the few crop alternatives during the summer; therefore, its reactivation is being reconsidered. The whitefly (Bemisia tabaci Genn, Biotype ‘B’) was one of the main causes of the reduction of soybean growing areas in Mexico as a result of direct damage to flower production and plant yield, as well as of the transmission of geminiviruses. During the summer of 2013-2014, a total of 11 soybean varieties were evaluated to determine the incidence of viral diseases in the Valley of Culiacán and Valle del Fuerte, Sinaloa, Mexico. Symptomatology, amplification of DNA by polymerase chain reaction (PCR) and sequence analysis of amplified fragments confirmed the incidence of yellow vein virus of huasteco pepper (PHYVV) in soybean grown in the west of Sinaloa, Mexico. Sequence analysis showed 100% of nucleotide and amino acid identities with respect to the PHYVV1GMES isolate from Mexico (GenBank accession number KT022087). This is the first report on the emergence of PHYVV in soybean in Mexico.

Keywords : begomovirus; enzymatic sequence; yellow vein virus of huasteco pepper.
