Real-time tracking of Tomato brown rugose fruit virus (ToBRFV) outbreaks in the Netherlands using Nextstrain.

ABSTRACT: Tomato brown rugose fruit virus (ToBRFV) is a Tobamovirus that was first observed in 2014 and 2015 on tomato plants in Israel and Jordan respectively. Since the first description, the virus has been reported from all continents except Oceania and Antarctica, and has been found infecting both tomato and pepper crops. In October 2019, the Dutch National Plant Protection Organization received a ToBRFV infected tomato sample as part of a generic survey targeting tomato pests. Presence of the virus was verified using Illumina sequencing. A follow-up survey was initiated to determine the extent of ToBRFV presence in the Dutch tomato horticulture and identify possible linkages between ToBRFV genotypes, companies and epidemiological traits. Nextstrain was used to visualize these potential connections. By November 2019, 68 companies had been visited of which 17 companies were found to be infected. The 50 ToBRFV genomes from these outbreak locations group in three main clusters, which are hypothesized to represent three original sources. No correlation was found between genotypes, companies and epidemiological traits, and the source(s) of the Dutch ToBRFV outbreak remain unknown. This paper describes a Nextstrain build containing ToBRFV genomes up to and including November 2019. Sharing data with this interactive online tool will enable the plant virology field to better understand and communicate the diversity and spread of this new virus. Organizations are invited to share data or materials for inclusion in the Nextstrain build, which can be accessed at https://nextstrain.nrcnvwa.nl/ToBRFV/20191231.

Project description:During the growing season of 2021-2022, a total of 145 symptomatic tomato leaf and fruit samples were collected from different locations in Riyadh Region, Saudi Arabia, showing a moderate-to-severe mosaic with dark green wrinkling, blistering, narrowing, and deformation with necrosis spot on tomato leaves, while irregular brown necrotic lesions, deformation, and yellowing spots rendering the fruits non-marketable were observed on tomato fruits. These samples were tested serologically against important tomato viruses using enzyme-linked immunosorbent assay (ELISA), and the obtained results showed that 52.4% of symptomatic tomato samples were found positive for Tomato brown rugose fruit virus (ToBRFV), wherein 12 out of 76 samples were singly infected; however, 64 out of 145 had mixed infection. A sample with a single infection of ToBRFV was used for mechanical inoculation into a range of different host plants; symptoms were observed weekly, and the presence of the ToBRFV was confirmed by ELISA and reverse transcription-polymerase chain reaction (RT-PCR). A total RNA was extracted from selected ELISA-positive samples, and RT-PCR was carried out using specific primers F-3666 and R-4718, which amplified a fragment of 1052 bp. RT-PCR products were sequenced in both directions, and partial genome nucleotide sequences were submitted to GenBank under the following accession numbers: MZ130501, MZ130502, and MZ130503. BLAST analysis of Saudi isolates of ToBRFV showed that the sequence shared nucleotide identities (99-99.5%) among them and 99-100% identity with ToBRFV isolates in different countries. A ToBRFV isolate (MZ130503) was selected for mechanical inoculation and to evaluate symptom severity responses of 13 commonly grown tomato cultivars in Saudi Arabia. All of the tomato cultivars showed a wide range of symptoms. The disease severity index of the tested cultivars ranged between 52% and 96%. The importance ToBRFV disease severity and its expanding host range due to its resistance breaking ability was discussed.
