Reaction of South American wheat genotypes to wheat streak mosaic virus
(Springer, 2018-08)Wheat streak mosaic virus (WSMV) is an emerging virus in South America that threatens cereal production. Genetic resistance is used in other regions as an effective strategy for management of this disease. The susceptibility ... -
Redefining the medicago sativa alphapartitiviruses genome sequences
(Elsevier, 2019-03-29)In Argentina, alfalfa (Medicago sativa L.) is a primary forage crop and a major feed component in dairy and beef cattle production systems. In 2010, we observed alfalfa plants showing symptoms of shortened internodes (bushy ... -
Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom
(Taylor & Francis, 2013)Sugars are part of an integrated redox system, since they are key regulators of respiration and photosynthesis, and therefore of the levels of reducing power, ATP and ROS. These elements are major determinants of the ... -
Relative incidence of cucurbit viruses and relationship with bio-meteorological variables
(Springer, 2020-02)Environmental heterogeneity can shape the plant-virus relationship, furthering the appearance of new diseases in crops, or altering disease incidence and severity. In this work, we studied the virus association with ... -
Salicylic acid determines differential senescence produced by two turnip mosaic virus strains involving reactive oxygen species and early transcriptomic changes
(2013-12)Losses produced by virus diseases depend mostly on symptom severity. Turnip mosaic virus (TuMV) is one of the most damaging and widespread potyvirus infecting members of the family Brassicaceae, including Arabidopsis ... -
Striking differences in the biological and molecular properties of onion and garlic isolates of onion yellow dwarf virus
(Springer, 2013-06)Complete nucleotide (nt) and deduced amino acid sequences of two onion yellow dwarf virus (OYDV) isolates showing mild and severe symptoms in onion but being unable to infect garlic were determined. The genomes consisted ... -
Temporal and spatial spread of potyvirus infection and its relationship to aphid populations visiting garlic crops
(Springer, 2014-11)The potyviruses Onion yellow dwarf virus (OYDV) and Leek yellow stripe virus (LYSV) are the main causes of serious losses in garlic crops worldwide. Both viruses are transmitted by aphid vectors in a non-persistent manner. ... -
The P0 protein encoded by cotton leafroll dwarf virus (CLRDV) inhibits local but not systemic RNA silencing
(2014-02)Plants employ RNA silencing as a natural defense mechanism against viruses. As a counter-defense, viruses encode silencing suppressor proteins (SSPs) that suppress RNA silencing. Most, but not all, the P0 proteins encoded ... -
The Plant Negative-Sense RNA Virosphere: Virus Discovery Through New Eyes
(Frontiers Media, 2020-09-16)The use of high-throughput sequencing (HTS) for virus diagnostics, as well as the importance of this technology as a valuable tool for discovery of novel viruses has been extensively investigated. In this review, we consider ... -
TMV induces RNA decay pathways to modulate gene silencing and disease symptoms
(2017)RNA decay pathways comprise a combination of RNA degradation mechanisms that are implicated in gene expression, development and defense responses in eukaryotes. These mechanisms are known as the RNA Quality Control or RQC ... -
Transgenic expression of tobacco mosaic virus capsid and movement proteins modulate plant basal defense and biotic stress responses in Nicotiana tabacum
(2012)Plant viruses cause metabolic and physiological changes associated with symptomatic disease phenotypes. Symptoms involve direct and indirect effects, which result in disruption of host physiology. We used transgenic ... -
Two novel flavi-like viruses shed light on the plant-infecting koshoviruses
(Springer, 2023-06-20)The family Flaviviridae is composed of viruses with a positive-sense single-stranded RNA genome and includes viruses that are important veterinary and human pathogens. Most members of the family are arthropod- and ... -
Use of 454-Pyrosequencing for the characterization of Sweet potato virus C and Sweet Potato Feathery Mottle virus Isolates fron Argentina and Development of a Multiplex one - step RT-PCR for Their Simultaneous Detection
(2016)454-pyrosequencing was applied as a tool to identify etiological agents involved in the symptoms observed in a sweet potato sample from Argentina. RNA was purified from symptomatic material and sequenced using a Roche 454 ... -
Use of silencing reporter and agroinfiltration transient assays to evaluate the potential of hpRNA construct to induce multiple tospovirus resistance
(2015-12)Tospoviruses are devastating plant viruses causing severe economic losses in a diverse range of crops worldwide. Here, we describe the development and evaluation of an RNA interference (RNAi) broad-spectrum virus resistance ... -
Viral diseases in common bean crops in Argentina
(Research Trends, 2020)Common bean (Phaseolus vulgaris) is the most important legume for direct human consumption worldwide. Several factors can affect bean yield, with viral diseases being responsible for losses in crop productivity, especially ... -
Virosis en zapallito de tronco
(EEA San Pedro, INTA, 2022)Las principales virosis que afectan al zapallito redondo son las producidas por virus del género Potyvirus. Hay 4 especies de este grupo presentes en Argentina, estos son: Watermelon mosaic virus (WMV), Zucchini yellow ... -
Virus del mosaico estriado del trigo (wheat streak mosaic virus, wsmv) en Argentina: detecciones en la campaña 2021 y medidas de prevención para 2022
(IPAVE - CIAP, INTA, 2022-04-05)Durante la campaña triguera 2021 se presentaron numerosas consultas en distintas regiones productoras sobre síntomas de amarillamiento foliar con sospecha de virosis. Este informe presenta los resultados de las detecciones ... -
Wheat curl mite, Aceria tosichella, and transmitted viruses: an expanding pest complex affecting cereal crops
(Springer, 2013-02)The wheat curl mite (WCM), Aceria tosichella, and the plant viruses it transmits represent an invasive mite-virus complex that has affected cereal crops worldwide. The main damage caused by WCM comes from its ability to ... -
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 ...
