Achaparramiento de la Alfalfa, una nueva enfermedad viral en Argentina
(Edición de Autor, 2018-03-26)En el año 2010 se determinó en Argentina una nueva enfermedad viral afectando alfalfa (Medicago sativa L.) cuyos síntomas no habían sido reportados previamente en el Continente Americano. Los síntomas comprenden un severo ... -
Alfalfa dwarf cytorhabdovirus P protein is a local and systemic RNA silencing supressor which inhibis program med RISC activity and prevents transitive amplification of RNA silencing
(2016)Plants employ RNA silencing as an innate defense mechanism against viruses. As a counter-defense, plant viruses have evolved to express RNA silencing suppressor proteins (RSS), which target one or more steps of the ... -
Alfalfa mosaic virus (AMV): genetic diversity and a new natural host
(Springer, 2021-10-15)Alfalfa mosaic virus (AMV) is a plant virus belonging to the genus Alfamovirus in the family Bromoviridae. AMV occurs worldwide and is one of the most important viruses affecting a large number of plant species, mainly ... -
Anthracnose on alfalfa caused by Colletotrichum americae-borealis in Córdoba province, Argentina
(Elsevier, 2021-06-06)Alfalfa is an important forage crop in Argentina, with a large area dedicated to its cultivation. However, plant diseases are a common cause of loss because they limit productivity and reduce forage quality. Anthracnose, ... -
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 ... -
Complete genome sequence and integrated protein localization and interaction map for alfalfa dwarf virus, which combines properties of both cytoplasmic and nuclear plant rhabdoviruses
(Elsevier, 2015-09)We have determined the full-length 14,491-nucleotide genome sequence of a new plant rhabdovirus, alfalfa dwarf virus (ADV). Seven open reading frames (ORFs) were identified in the antigenomic orientation of the negative-sense, ... -
Complete genome sequence of a new enamovirus from Argentina infecting alfalfa plants showing dwarfism symptoms
(2016)Alfalfa dwarf disease, probably caused by synergistic interactions of mixed virus infections, is a major and emergent disease that threatens alfalfa production in Argentina. Deep sequencing of diseased alfalfa plant samples ... -
Complete nucleotide sequence of Alfalfa mosaic virus isolated from alfalfa (Medicago sativa L.) in Argentina
(Springer, 2014-06)The complete nucleotide sequence of an Alfalfa mosaic virus (AMV) isolate infecting alfalfa (Medicago sativa L.) in Argentina, AMV-Arg, was determined. The virus genome has the typical organization described for AMV, and ... -
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 ... -
Efecto del fungicida azoxystrobin sobre el crecimiento micelial de colletotrichum spp., agente causal de la antracnosis de la alfalfa
(Asociación Argentina de Fitopatólogos, 2021-09-22)Antracnosis es una de las enfermedades más importantes que afectan a la alfalfa (Medicago sativa L.) a nivel mundial. Generalmente la especie que más afecta es Colletotrichum trifolii. En Argentina, además de C. trifolii ... -
Estudios epidemiológicos del alfalfa enamovirus-1 en el cultivo de alfalfa de Argentina
(Asociación Argentina de Fitopatólogos, 2021-09-22)El Alfalfa enamovirus 1 (AEV 1 Género Enamovirus Familia Luteoviridae identificado en 2016 como miembro de una nueva especie viral, es uno de los virus detectados en alfalfas con síntomas de achaparramiento, la que impacta ... -
First biological data of Ceresa nigripectus [Hemiptera:Membracidae], a common treehopper on alfalfa crops in Argentina
(2014-12)Alfalfa (Medicago sativa L.; Fabaceae) is essential for argentinean agricultural development, but diseases like “witches´ broom», caused by the ArAWB phytoplasma, are limiting factors for the production of this crop. ... -
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 ... -
Geographical distribution, genetic studies and vector transmission of alfalfa enamovirus-1 infecting alfalfa crop in Argentina
(Springer, 2020-07)Alfalfa (Medicago sativa L.) growing areas of Argentina were surveyed between 2010 and 2018 to determine the geographical distribution and analyse the genetic diversity among alfalfa enamovirus-1 (AEV-1) isolates. The virus ... -
