Amesuviridae: a new family of plant-infecting viruses in the phylum Cressdnaviricota, realm Monodnaviria
(Springer, 2023-08-10)The phylum Cressdnaviricota comprises viruses with single-stranded, circular DNA genomes that encode an HUH-type endonuclease (known as Rep). The phylum includes two classes, eight orders, and 11 families. Here, we report ... -
An analysis of the genomic variability of the phytopathogenic mollicute Spiroplasma kunkelii
(American Phytopathological Society, 2013-02)Corn stunt disease has become a factor limiting maize production in some areas of the Americas in recent years. Although resistant maize genotypes have been developed in the past, this resistance has been unstable over ... -
An in silico analysis revealed a novel evolutionary lineage of putative mitoviruses
(Wiley, 2022-09-09)Mitoviruses (family Mitoviridae) are small capsid-less RNA viruses that replicate in the mitochondria of fungi and plants. However, to date, the only authentic animal mitovirus infecting an insect was identified as Lutzomyia ... -
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 ... -
An insight into the sialome, mialome and virome of the horn fly, Haematobia irritans
(BMC, 2019-07-29)Background: The horn fly (Haematobia irritans) is an obligate blood feeder that causes considerable economic losses in livestock industries worldwide. The control of this cattle pest is mainly based on insecticides; ... -
An insight into the sialotranscriptome and virome of Amazonian anophelines
(BioMed Central, 2019)Background: Saliva of mosquitoes contains anti-platelet, anti-clotting, vasodilatory, anti-complement and antiinflammatory substances that help the blood feeding process. The salivary polypeptides are at a fast pace ... -
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 ... -
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 ... -
An Unwanted Association: The Threat to Papaya Crops by a Novel Potexvirus in Northwest Argentina
(MDPI, 2022-10-19)An emerging virus isolated from papaya (Carica papaya) crops in northwestern (NW) Argentina was sequenced and characterized using next-generation sequencing. The resulting genome is 6667-nt long and encodes five open reading ... -
Analysis of the coding-complete genomic sequence of groundnut ringspot virus suggests a common ancestor with tomato chlorotic spot virus
(2016)Groundnut ringspot virus (GRSV) and tomato chlorotic spot virus (TCSV) share biological and serological properties, so their identification is carried out by molecular methods. Their genomes consist of three segmented RNAs: ... -
