The 18S–25S ribosomal RNA unit of yerba mate (Ilex paraguariensis A. St.-Hil.)
(2016)We present the first report of the transcribed 18S–25S ribosomal DNA (rDNA) unit of the South American crop Ilex paraguariensis. This tree is consumed as an infusion named “mate”. Next-generation sequencing data were ... -
The Activity of the Chloroplastic Ndh Complex Is Regulated by Phosphorylation of the NDH-F Subunit
(American Society of Plant Biologists, 2003-05-01)Hydrogen peroxide (H2O2) induces increases, to different degrees, in transcripts, protein levels, and activity of the Ndh complex (EC 1.6.5.3). In the present work, we have compared the effects of relatively excess light, ... -
The chlorotic symptom induced by Sunflower chlorotic mottle virus is associated with changes in redox-related gene expression and metabolites
(Elsevier, 2012-08-18)Systemic infections are commonly associated with changes in host metabolism and gene expression. Sunflower chlorotic mottle virus (SuCMoV) causes systemic infection with sugar increase, photoinhibition and increase in ... -
The effect of Leucaena leucocephala on beef production and its toxicity in the Chaco Region of Argentina
(CIAT, 2014)Hedgerows of the fodder tree legume, Leucaena leucocephala ssp. glabrata (leucaena), planted with a companion grass, provide productive, profitable and sustainable tropical pasture (Shelton and Dalzell 2007). Although ... -
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 ... -
The prevalence of Coxiella burnetii shedding in dairy goats at the time of parturition in an endemically infected enterprise and associated milk yield losses
(Springer Nature, 2018-11)Background: This was a panel study of the prevalence of C. burnetii infection in does in an endemic dairy goat enterprise in Victoria, Australia. Our first objective was to determine the prevalence of does shedding C. ... -
The role of inoculum identity in drought stress mitigation by arbuscular mycorrhizal fungi in soybean
(2015-01)It is well known that arbuscular mycorrhizal fungi (AMF) effects on plant growth largely depend on fungus identity. The objective of this study was to test whether three individual AMF isolates and their mixture mitigate ... -
Tolerancia a la inundación de especies gramíneas forrajeras megatérmicas : bases ecofisiológicas relacionadas con su instalación y producción
(Facultad de Agronomía, Universidad de Buenos Aires, 2013)La inundación es un factor importante que afecta la implantación y producción de especies forrajeras en ecosistemas de pastizales anegables. Chloris gayana K. y Panicum coloratum L. son dos gramíneas tropicales cuyo uso ... -
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 ... -
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 ... -
TOR and SnRK1 signaling pathways in plant response to abiotic stresses: Do they always act according to the "yin-yang" model?
(2019-08-13)Plants are sessile photo-autotrophic organisms continuously exposed to a variety of environmental stresses. Monitoring the sugar level and energy status is essential, since this knowledge allows the integration of external ... -
