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
(Springer, 2020-03)Watermelon mosaic virus (WMV) is an economically important virus of cucurbit crops in Argentina. The available information on genetic variability must be continuously updated. In this study, we assessed the molecular ... -
