Abstract

First report of Groundnut ringspot orthotospovirus infecting field pea (Pisum sativum L.) crop in Brazil.

Abstract

Field pea (Pisum sativum) cultivar Axé with symptoms of orthotospovirus infection (∼5% incidence) were collected under open field conditions in Brasília, Distrito Federal, Central Brazil. Ten leaf samples displaying apical chlorosis, necrosis, and deformation were evaluated. Based on the results of ELISA tests, PCR assays and nucleotide sequence analysis, the causal agent was identified as Groundnut ringspot virus (GRSV). Fabaceae members have been reported as natural TSWV hosts in Brazil, including chickpea, lentil and field pea. So far, only peanut has been reported as a Fabaceae host of GRSV in the country. This is thought to be the first worldwide report of pea-infecting GRSV isolates.
