Abstract
AbstractPeanut (Arachis hypogaea L.) plants showing Tospovirus‐like symptoms were observed in Córdoba province (central Argentina). Peanut plants were collected and tested to identify the causal agent. Tospovirus‐like particles were observed by electron microscopy and Groundnut ringspot virus (GRSV) was identified by double antibody sandwich‐enzyme‐linked immunosorbent assay (DAS‐ELISA) and reverse transcription‐polymerase chain reaction (RT‐PCR). Partial nucleotide and deduced amino acid sequences of the nucleocapsid (N) gene indicated a high degree of identity with other GRSV sequences. This is the first report of the GRSV occurrence on peanuts in Argentina.
