In August 2021, symptoms of a viral-like infection were observed on
the leaves and fruits of tomato plants, cvs. Emperador RZF1 (Rijk
Zwaan, The Netherlands) Maxifort, Eshkol and 4129 (Seminis Veg-
etable Seeds, USA) in a 3.2 ha greenhouse complex in Isfahan province,
Iran. Plants had been raised in Iran from imported seed. The symptoms
consisted of severe mosaic and deformation of leaves (especially the
upper and young leaves) and chlorotic and brown necrotic spots on the
fruits (Figure 1). These symptoms resembled those of Tomato brown
rugose fruit virus (ToBRFV) reported elsewhere (Salem et al., 2016).
About 30% of plants were affected by symptoms across the green-

house complex. The cultivars Eshkol and 4129 were more severely
affected than others.
Extracts from leaf and fruit samples induced the formation of
necrotic local lesions on mechanically inoculated Nicotiana glutinosa
(Figure 2) indicating the possible presence of a tobamovirus. The sam-
ples were also subjected to RT-PCR using ToBRFV-specific primers:
ToBRFV-F (5’-GAAGTCCCGATGTCTGTAAGG-3’) and ToBRFV-R (5’-
GTGCCTACGGATGTGTATGA-3’) (Ling et al., 2019). The fragment
obtained from the PCR reaction (842 bp) was isolated, purified after
size confirmation (by comparison with molecular weight markers), and
