Mitovirus and Mitochondrial Coding Sequences from Basal Fungus Entomophthora muscae
(MDPI, 2019-04-17)Fungi constituting the Entomophthora muscae species complex (members of subphylum Entomophthoromycotina, phylum Zoopagamycota) commonly kill their insect hosts and manipulate host behaviors in the process. In this study, ... -
Molecular characterization of a novel cytorhabdovirus with a unique genomic organization infecting yerba mate (Ilex paraguariensis) in Argentina
(Springer, 2020-04)The genome of a novel rhabdovirus was detected in yerba mate (Ilex paraguariensis St. Hil.). The newly identified virus, tentatively named "yerba mate virus A" (YmVA), has a genome of 14,961 nucleotides. Notably, eight ... -
Molecular characterization of a phytoplasma of the ash yellows group occurring in strawberry (Fragaria x ananassa Duch.) plants in Argentina
(2013-01)Strawberry (Fragaria x ananassa Duch. cv. Camino Real) plants showing phyllody symptoms were detected in production fields in Bella Vista (Corrientes province, Argentina). DNA from all symptomatic samples analyzed yielded ... -
Molecular characterization of effector protein SAP54 in Bellis virescence phytoplasma (16SrIII-J)
(Springer, 2019-06-03)Phytoplasmas are wall-less bacteria with a parasitic lifestyle responsible for numerous plant diseases worldwide. Since the introduction of next generation sequencing technologies, genome wide studies of these pathogens ... -
Molecular characterization of the 5S rDNA non-transcribed spacer and reconstruction of phylogenetic relationships in Capsicum
(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2021)Capsicum includes ca. 41 species of chili peppers. In this original report we PCR amplified, cloned, sequenced and characterized the 5S rDNA non-transcribed spacer -NTS- in 23 taxa of nine clades of Capsicum, divergent at ... -
Molecular characterization of the garlic virus B genome and evidence of allexivirus recombination
(Springer, 2018)Molecular characterization is important for differentiating allexiviruses species, since detection by serological methods may be uncertain. Eight different species have been reported as infecting garlic: Garlic virus A, ... -
Molecular characterization of yerba mate chlorosis-associated virus, a putative cytorhabdvirus infecting yerba mate (Ilex paraguariensis)
(2017-08)We present the molecular characterization of a new virus infecting yerba mate (Ilex paraguariensis St. Hil.) in Argentina. Deep sequencing of diseased yerba mate plants showing chlorotic linear patterns, chlorotic rings, ... -
Molecular detection of Thecaphora frezzi in peanut (Arachis Hypogaea L.) seeds
(2016)Thecaphora frezii is the causal agent of peanut smut, important disease in the Argentine production area. The pathogen can be dispersed by kernels, through surface contamination or small lesions. The aim of this work was ... -
Molecular identification and characterization of two rubber dandelion amalgaviruses
(2017-12-05)The Amalgaviridae family is composed of persistent viruses that share the genome architecture of Totiviridae and gene evolutionary resemblance to Partitiviridae. A single Amalgavirus genus has been assigned to this family, ... -
Molecular sequence data of Thecaphora frezii affecting peanut crops in Argentina
(Springer, 2013-12)In Argentina, Thecaphora frezii is the causal agent of peanut smut, causing severe yield losses in peanut growing areas. In this work sequence data of the large ribosomal subunit (28S rDNA) of four T. frezii specimens from ... -
Molecular variability of watermelon mosaic virus isolates from Argentina
