Tomato fruit blotch virus cytopathology strengthens evolutionary links between plant blunerviruses and insect negeviruses.
Tomato fruit blotch virus (ToFBV) is a blunervirus that causes blotches on mature tomato (Solanum lycopersicon L.) fruits in Italy and Australia in 2020, and was newly detected in Brazil. A cytological study on pericarp tissues from the blotched areas of infected fruits collected in Brasília, Brazil, revealed characteristic cell alterations. Small and slender bacilliform particles (ca. 25 nm wide × 100 nm long) were found accumulating in the perinuclear space and the lumen of the endoplasmic reticulum of the epidermis, peri- and mesocarp cells. No viroplasmlike inclusion was observed either in the nuclei or in the cytoplasm.
