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 ... -
Heat and water stressed field-grown soybean : a multivariate study on the relationship between physiological-biochemical traits and yield
(Elsevier, 2018-04)Heat stress (HS) combined with water stress (WS) negatively impact soybean [Glycine max (L.) Merr.] production. The aims of this research were to quantify the combined effect of HS and WS during grain filling (GF) on grain ... -
Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ... -
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 ... -
Distrofia muscular nutricional en corderos de raza Dorper en el Noroeste Argentino
(Sociedad de Medicina Veterinaria, Argentina, 2018-05-02)Se describe un brote de distrofia muscular nutricional (DMN) en el noroeste argentino que afectó a una majada de ovinos Dorper. En corderos, la incidencia fue de 18% y la mortalidad del 98%. Los signos clínicos fueron ... -
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 ... -
Efecto de la intersiembra pastura-maíz sobre la microbiota edáfica en sistema pastoril bovino del Chaco semiárido
(Asociación Argentina Ciencia del Suelo (AACS), 2018-05-15)La combinación de crecimiento demográfico, aumento de los ingresos y urbanización, plantea un desafío sin precedentes a los sistemas alimentarios y agrícolas. De manera similar, la expansión agrícola ocurrida en el noroeste ... -
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, ... -
