Genomic Diversity of Tomato Brown Rugose Fruit Virus in Canadian Greenhouse Production Systems.

ABSTRACT: Tomato brown rugose fruit virus (ToBRFV) is a recently emerged viral pathogen in the Tobamovirus genus first observed in 2014 in the Middle East that has since spread worldwide, causing significant losses in greenhouse tomato production. ToBRFV is easily mechanically transmitted and can escape the durable Tm-2² resistance gene, facilitating its global spread. Seed companies have identified novel sources of resistance and introduced these resistance traits into commercial cultivars. The identity, number, and mechanisms of these putative novel resistance genes are largely unknown but could be exerting selective pressures on ToBRFV. Here, we report 15 new ToBRFV genomic sequences from Canadian greenhouse production systems in susceptible and novel resistant or toleran
