(Springer; Australasian Plant Pathology Society, 2018-07)Three begomoviruses were identified in bean crops in northwestern Argentina: Bean golden mosaic virus (BGMV), Tomato yellow spot virus (ToYSV) and Soybean blistering mosaic virus (SbBMV). Nucleic acid hybridization probes ... -
Impact of yellow leaf virus on sugarcane commercial fields
(Springer, 2020-11-17)A survey of Sugarcane yellow leaf virus (SCYLV) was conducted in northern Argentina in 2015 and 2016 using tissue blot immunoassay (TBIA). Results showed plant infection rates of 2.2–86.7% in sugarcane commercial fields ... -
Incidence and prevalence of aphid-borne viruses infecting strawberry in Argentina
(Wiley, 2018-07)The incidence and prevalence of strawberry viruses were determined in surveys of randomly selected strawberry plants grown in different regions of Argentina. In 2009 and 2010, 1034 plants from 28 fields and 1060 plants ... -
Incidence of Garlic common latent virus in Argentina, and phylogenetic and recombination analyses of isolates = Incidência de Garlic common latent virus na Argentina, e análise filogenética e de recombinação de isolados
(Embrapa, 2015-05)The objective of this work was to estimate the incidence and prevalence of Garlic common latent virus (GarCLV) in the main production regions of garlic (Allium sativum) in Argentina, and to perform phylogenetic and ... -
Molecular characterization of a novel cytorhabdovirus with a unique genomic organization infecting yerba mate (Ilex paraguariensis) in Argentina
(Springer, 2020-04)The genome of a novel rhabdovirus was detected in yerba mate (Ilex paraguariensis St. Hil.). The newly identified virus, tentatively named "yerba mate virus A" (YmVA), has a genome of 14,961 nucleotides. Notably, eight ... -
Molecular characterization of the garlic virus B genome and evidence of allexivirus recombination
(Springer, 2018)Molecular characterization is important for differentiating allexiviruses species, since detection by serological methods may be uncertain. Eight different species have been reported as infecting garlic: Garlic virus A, ... -
Molecular characterization of yerba mate chlorosis-associated virus, a putative cytorhabdvirus infecting yerba mate (Ilex paraguariensis)
(2017-08)We present the molecular characterization of a new virus infecting yerba mate (Ilex paraguariensis St. Hil.) in Argentina. Deep sequencing of diseased yerba mate plants showing chlorotic linear patterns, chlorotic rings, ... -
Molecular identification and characterization of two rubber dandelion amalgaviruses
(2017-12-05)The Amalgaviridae family is composed of persistent viruses that share the genome architecture of Totiviridae and gene evolutionary resemblance to Partitiviridae. A single Amalgavirus genus has been assigned to this family, ... -
Novel bird’s-foot trefoil RNA viruses provide insights into a clade of legume-associated enamoviruses and rhabdoviruses
(Springer, 2019-03-09)Here, we report the identification and characterization of two novel viruses associated with bird’s-foot trefoil. Virus sequences related to those of enamoviruses (ssRNA (+); Luteoviridae; Enamovirus) and nucleorhabdoviruses ... -
Occurrence and characterization of a severe isolate of Watermelon mosaic virus from Argentina
(2016)More than 50 viruses have been reported in cucurbit crops worldwide. In Argentina, cucurbit viruses have been associated with important yield losses. The most prevalent and widespread potyvirus is Watermelon mosaic virus ... -
Orthotospovirus disease epidemic: molecular characterization and incidence in peanut crops
