Complete genome sequence of sunflower ring blotch virus, a new potyvirus infecting sunflower in Argentina
(Springer, 2017-06)The complete genome sequence of sunflower ring blotch virus (SuRBV), a previously undescribed potyvirus infecting sunflower in Argentina, is reported. The SuRBV genome comprises 9555 nucleotides (nt) and encodes a polyprotein ... -
Tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in Argentina
(Springer, 2015-02)Begomoviruses seriously threaten tomato production in South America. Here, we present the molecular characterization of a novel tomato-infecting begomovirus isolated in Argentina and demonstrate its infectivity. After ... -
Bean leafroll virus (BLRV) in Argentina: molecular characterization and detection in alfalfa fields
(Springer, 2016-09)Alfalfa (Medicago sativa L.) is the main forage crop in Argentina and plays an essential role in the animal production chain, but it can be negatively affected by many factors, such as viral diseases. Here, we report the ... -
First report of a ‘Candidatus phytoplasma pyri’ strain in Argentina
(Springer, 2017-12)During the 2015 growing season, peach plants (Prunus persica) showing chlorotic, curling leaves and midrib thickening were detected in production fields in Mendoza province (Midwest region, Argentina). These symptoms ... -
Distinct strains of the re-emergent Cassava common mosaic virus (genus: Potexvirus) infecting cassava in Argentina
(Wiley, 2018-10)Cassava common mosaic disease (CCMD) has been reported in all regions where cassava is grown in the Americas and the causal agent, Cassava common mosaic virus (CsCMV), has been identified as a mechanically transmitted ... -
Papaya ringspot virus W infecting Luffa aegyptiaca in Cuba
(Springer, 2017-12)Luffa aegyptiaca (sponge gourd) plants showing severe leaf mosaic and deformation symptoms were observed in Villa Clara, Cuba. Electron microscopy observations of leaf dip preparations revealed flexuous filamentous particles, ... -
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, ... -
Meta‐analysis of fungicide efficacy on soybean target spot and cost–benefit assessment
(Wiley, 2018)Target spot of soybean has spread in Brazil, the southeastern United States and Argentina in the last decade. A collaborative network of field Uniform Fungicide Trials (UFT) in Brazil was created in 2011 to study the target ... -
Geographical distribution and first molecular detection of an Emaravirus, High Plains wheat mosaic virus, in Argentina
(Springer, 2017-11)High Plains wheat mosaic virus (HPWMoV) has recently been assigned to genus Emaravirus and is the causal agent of High Plains disease. In this work the geographical distribution and first molecular detection of HPWMoV in ... -
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 ... -
Distribution and genetic variability of alfalfa dwarf virus, a cytorhabdovirus associated with alfalfa dwarf disease in Argentina
(Springer, 2018-08)In 2010, a novel cytorhabdovirus named alfalfa dwarf virus (ADV) was detected for the first time in lucerne crops in Argentina showing dwarfism, in mixed infections with several other viruses. ADV appears to be endemic to ... -
Detection and identification of a 16SrIII-J phytoplasma affecting cassava (Manihot esculenta Crantz) in Argentina
(Springer; Australasian Plant Pathology Society, 2018-12)Cassava plants displaying symptoms of dwarfing, witches’ broom, and chlorosis, were detected in production fields located in Misiones province Argentina. The RFLP profiles and phylogenetic analyses based on 16S rRNA and ... -
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 ... -
Identification and molecular characterization of a novel circular single-stranded DNA virus associated with yerba mate in Argentina
(Springer, 2018-10)A single-stranded DNA (ssDNA) virus was detected in Yerba mate samples showing chlorotic linear patterns, chlorotic rings and vein yellowing. The full-genome sequences of six different isolates of this ssDNA circular virus ... -
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 ... -
A strain of Bacillus subtilis subsp. subtilis shows a specific antagonistic activity against the soil-borne pathogen of onion Setophoma terrestris
(2015)Pink Root is among the major diseases of onion and its causal agent, Setophoma terrestris, is one of the most severe pathogens in soils of tropical and subtropical climates. The management of Pink Root is difficult and the ... -
FISH-mapping of the 5S rDNA locus in chili peppers (Capsicum-Solanaceae)
(2016)We present here the physical mapping of the 5S rDNA locus in six wild and fi ve cultivated taxa of Capsicum by means of a genus-specifi c FISH probe. In all taxa, a single 5S locus per haploid genome that persistently mapped ... -
Molecular identification and characterization of two rubber dandelion amalgaviruses
