A barnavirus sequence mined from a transcriptome of the Antarctic pearlwort Colobanthus quitensis
(2018-03)Because so few viruses in the family Barnaviridae have been reported, we searched for more of them in public sequence databases. Here, we report the complete coding sequence of Colobanthus quitensis associated barnavirus ... -
An Integrated Physical Map of the Cultivated Hot Chili Pepper, Capsicum baccatum var. Pendulum
(2017)Capsicum baccatum var. Pendulum is the most frequently cultivated chili pepper in South America. This taxon is an outstanding source for breeding programs and genetic improvement in the genus, since its traits can be ... -

(2017-06)This contribution contains data related to the research article entitled “The 18S-25S ribosomal RNA unit of yerba mate (Ilex paraguariensis A. St.-Hil.)” (Aguilera et al., 2016) [1]. Through a bioinformatic approach involving ... -
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 ... -
Efficiency of cytogenetic methods in detecting a chromosome rearrangement induced by ionizing radiation in a cultivated chili pepper line (Capsicum baccatum var. pendulum – Solanaceae)
(2014)Purpose: To locate transient chromosome aberrations on a selected pepper cultivar and determine the tracing efficiency of different cytogenetic methods. Materials and methods: Seeds from Capsicum baccatum var. pendulum ... -
The complete genome of a putative endornavirus identified in yerba mate (Ilex paraguariensis St. Hil.)
(2014-10)We present the first report of a virus infecting the subtropical tree crop yerba mate (Ilex paraguariensis St. Hil.). Total RNA purification, followed by next-generation sequencing, transcripts assembly and annotation, ... -
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 ... -
Plant microRNAs: Recent Advances and Future Challenges
(2014-12)MicroRNAs (miRNAs) are small ∼20–24 nt species of non-coding RNAs that modulate plant gene expression by means of gene silencing through sequence-specific inhibition of target mRNAs. MiRNAs derive from pol-II transcription ... -
An In Vitro Method for Studying the Three-Way Interaction between Soybean, Rhizophagus irregularis and the Soil-Borne Pathogen Fusarium virguliforme
(2017-06)In this work, we described an in vitro system adequate for investigating the pathosystem soybean/arbuscular mycorrhizal fungi (AMF)/Fusarium virguliforme. Pre-mycorrhized plantlets with Rhizophagus irregularis were infected ... -
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 ... -
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 ... -
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 ... -
Identification of three novel subgroups within the X-disease group phytoplasma associated with strawberry redness disease
(2017-04)Strawberry plants showing symptoms of lethal redness disease were found in production fields located in Tucumán province, Argentina. The presence of phytoplasmas was confirmed by PCR of 16S rDNA gene using phytoplasma ... -
An RNA Virome Associated to the Golden Orb-Weaver Spider Nephila clavipes
(2017-10)The golden orb-weaver spider Nephila clavipes, known for its sexual size dimorphism, is abundant and widespread in the New World. The first annotated genome of orb-weaver spiders, exploring N. clavipes, has recently been ... -
