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, ... -
Tomato apical leaf curl virus: a novel, monopartite geminivirus detected in tomatoes in Argentina
(2018-01)Plant viruses that are members of the Geminiviridae family have circular single-stranded DNA (ssDNA) genome and are responsible for major crop diseases worldwide. We have identified and characterized a novel monopartite ... -
Complete genome sequence of maize yellow striate virus, a new cytorhabdovirus infecting maize and wheat crops in Argentina
(Springer, 2018-01)A rhabdovirus infecting maize and wheat crops in Argentina was molecularly characterized. Through next-generation sequencing (NGS) of symptomatic leaf samples, the complete genome was obtained of two isolates of maize ... -
Genome characterization of an Argentinean isolate of alfalfa leaf curl virus
(2018-03)We investigated the molecular characteristics of an Argentinean isolate of alfalfa leaf curl virus (ALCV-Arg), a virus of the genus Capulavirus in the family Geminiviridae that was isolated from alfalfa plants showing ... -
A barnavirus sequence mined from a transcriptome of the Antarctic pearlwort Colobanthus quitensis
(2018-03)Because so few viruses in the family Barnaviridae have been reported, we searched for more of them in public sequence databases. Here, we report the complete coding sequence of Colobanthus quitensis associated barnavirus ... -
Identification and characterization of a new potyvirus infecting cucurbits
(Springer, 2018-03)A new potyvirus, tentatively named cucurbit vein banding virus (CVBV), was identified in crops of cucurbits in San Pedro (Buenos Aires, Argentina). The complete genome sequences of two isolates of CVBV were obtained by ... -
Improvement of conditional Cre-lox system through application of the regulatory sequences from Cowpea mosaic virus
(Springer, 2018-04)To study the impact of regulatory sequences from Cowpea mosaic virus (CPMV) on Cre-mediated recombination rates, the cre gene was flanked by the 5′ non-translated and 3′ non-translated regions of CPMV. This cre configuration ... -
Yield losses of asymptomatic strawberry plants infected with Strawberry mild yellow edge virus
(2018-04)After successive vegetative propagation cycles, strawberry (Fragaria × ananassa Duch.) plants often accumulate multiple virus species that result in viral symptoms and losses in yield and quality. However, strawberry plants ... -
Dataset of the first transcriptome assembly of the tree crop “yerba mate” (Ilex paraguariensis) and systematic characterization of protein coding genes
(2018-04)This contribution contains data associated to the research article entitled “Exploring the genes of yerba mate (Ilex paraguariensis A. St.-Hil.) by NGS and de novo transcriptome assembly” (Debat et al., 2014) [1]. By means ... -
Expanding the size limit of RNA viruses: Evidence of a novel divergent nidovirus in California sea hare, with a ~35.9 kb virus genome
(BioRxiv, 2018-04-24)While RNA viruses thrive with massive structural and functional diversity, their genomes size variation is particularly low, ranging only from ~2-to-33 kb. Here, I present the characterization of RNA sequences corresponding ... -
Evidence for contemporary plant mitoviruses
(2018-05)Mitoviruses have small RNA(+) genomes, replicate in mitochondria, and have been shown to infect only fungi to date. For this report, sequences that appear to represent nearly complete plant mitovirus genomes were recovered ... -
Response of soil microbial communities to agroecological versus conventional systems of extensive agriculture
(2018-05)World population growth has led to a rise in resource demands imposed on agricultural systems, generating an increased global use of natural resources. However, agroecology proposes self-regulation in order to achieve a ... -
Identification of the first endogenous Ophiovirus sequence
(BioRxiv, 2018-05-05)Endogenous viral elements (EVEs) are sequences in eukaryotic genomes that are derived from the ancestral integration of viral sequences into germline cells. Ophioviruses (family Ophioviridae) are a recently established ... -
Characterization of Argentinian Endemic Aspergillus flavus Isolates and Their Potential Use as Biocontrol Agents for Mycotoxins in Maize
(American Phytopathological Society, 2018-05-07)Maize (Zea mays L.) is a highly valuable crop in Argentina, frequently contaminated with the mycotoxins produced by Aspergillus flavus. Biocontrol products formulated with atoxigenic (nontoxic) strains of this fungal species ... -
Transcriptional Changes in Mycorrhizal and Nonmycorrhizal Soybean Plants upon Infection with the Fungal Pathogen Macrophomina phaseolina
(American Phytopathological Society, 2018-06-19)Macrophomina phaseolina is a soil-borne fungal pathogen with a wide host range that causes charcoal rot in soybean [Glycine max (L.) Merr.]. Control of the disease is a challenge, due to the absence of genetic resistance ... -
Identification, molecular characterization and relative incidence of begomoviruses infecting bean crops in northwestern Argentina: an update
(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 ... -
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 ... -
Influence of 12-years of NPS fertilization on soil quality, microbial community profile and activity under conservation agricultural management
(Asociación Argentina Ciencia del Suelo, 2018-07)Microbial parameters are considered to be potential indicators of soil quality since soil microorganisms can respond rapidly to agricultural management systems. The effect of long-term fertilizer applications on soil, ... -
