Abstract

Brazil is currently the world's largest passion fruit producer, with an estimated production of 703 489 metric tonnes harvested in an area of 49 889 ha, 70% of which is concentrated in the northeast region. In July 2017, eight samples of passionflower vines (Passiflora edulis, cultivar Flora Brasil-200), from Mossoró County, state of Rio Grande do Norte, exhibiting severe mosaic accompanied by yellow spots, leaf deformation and blisters were received in the laboratory of Plant Virology (Escola Superior de Agricultura "Luiz de Queiroz"/Universidade de São Paulo) for diagnosis. The passion fruit plants were heavily infested by whitefly. Because symptoms resembled those associated with begomovirus infection previously reported for passionflower, total DNA was extracted from all leaf samples. Based on the results of rolling circle amplification, polymerase chain reaction assay and nucleotide sequencing, the causal agent was identified as Sida mottle Alagoas virus (SiMAV). The whitefly was identified as Bemisia tabaci Middle East-Asia Minor 1 (formerly biotype B) based on DNA sequencing results. This is thought to be the first report of SiMAV naturally infecting passionflower in Brazil.
