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 ... -
Evidence of cassava common mosaic virus in cassava shoot apical meristems
(Wiley, 2023-05-12)Cassava (Manihot esculenta) is an allogamous and highly heterozygous species. For this reason, its seeds are not used for production purposes (Ceballos & de la Cruz, 2002); instead, plantations are established using stem ... -
Evolution of SARS-CoV-2 during the first year of the COVID-19 pandemic in Northwestern Argentina
(Elsevier, 2022-09-28)Studies about the evolution of SARS-CoV-2 lineages in different backgrounds such as naive populations are still scarce, especially from South America. This work aimed to study the introduction and diversification pattern ... -
Examples of Risk Tools for Pests in Peanut (Arachis hypogaea) Developed for Five Countries Using Microsoft Excel
(Entomological Society of America, 2022-08-03)Suppressing pest populations below economically-damaging levels is an important element of sustainable peanut (Arachis hypogaea L.) production. Peanut farmers and their advisors often approach pest management with similar ... -
Expanding the Repertoire of the Plant-Infecting Ophioviruses through Metatranscriptomics Data
(MDPI, 2023-03-25)Ophioviruses (genus Ophiovirus, family Aspiviridae) are plant-infecting viruses with non-enveloped, filamentous, naked nucleocapsid virions. Members of the genus Ophiovirus have a segmented single-stranded negative-sense ... -
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 ... -
Exploring species composition and population dynamics of thrips (Thysanoptera: Thripidae) in peanut crops in Argentina
(Springer, 2021-04-26)Thrips (Thysanoptera: Thripidae) are major pests of peanut (Arachis hypogaea L.). They cause feeding damage and indirect injuries transmitting plant viruses. In Argentina, peanut is commonly affected by thrips. The crop ... -
