Genome-wide identification of MITE-derived microRNAs and their targets in bread wheat
Crescente, Juan Manuel; Zavallo, Diego; Del Vas, Mariana; Asurmendi, Sebastian; Helguera, Marcelo; Fernandez, Elmer; Vanzetti, Leonardo Sebastian (BioMed Central, 2022-02)Background: Plant miRNAs are a class of small non-coding RNAs that can repress gene expression at the post-transcriptional level by targeting RNA degradation or promoting translational repression. There is increasing ... -
ICTV virus taxonomy profile : Sedoreoviridae 2022
Matthijnssens, Jelle; Attoui, Houssam; Bányai, Krisztián; Brussaard, Corina P.D.; Danthi, Pranav; Del Vas, Mariana; Dermody, Terence S.; Duncan, Roy; Fāng, Qín; Johne, Reimar; Mertens, Peter P.C.; Jaafar, Fauziah Mohd; Patton, John T.; Sasaya, Takahide; Suzuki, Nobuhiro; Wei, Taiyun (Microbiology Society, 2022-10)Sedoreoviridae is a large family of icosahedral viruses that are usually regarded as non- enveloped with segmented (10–12 linear segments) dsRNA genomes of 18–26 kbp. Sedoreovirids have a broad host range, infecting mammals, ... -
In vivo subcellular localization of Mal de Río Cuarto virus (MRCV) non-structural proteins in insect cells reveals their putative functions
Maroniche, Guillermo Andrés; Mongelli, Vanesa Claudia; Llauger, Gabriela; Alfonso, Victoria; Taboga, Oscar Alberto; Del Vas, Mariana (Elsevier, 2012-09)The in vivo subcellular localization of Mal de Río Cuarto virus (MRCV, Fijivirus, Reoviridae) non-structural proteins fused to GFP was analyzed by confocal microscopy.
