![]() ![]() The tobamoviruses are highly stable and kept infectious in soil containing buried virus-contaminated plants, on various agricultural facility tool surfaces, in seeds, and upon adhering to beneficial pollinator body parts. ![]() The prevalent route of tobamovirus infection is via mechanical plant manipulations. These symptoms are primarily attributed to infections by viruses belonging to the Tobamovirus genus, in the Virgaviridae family. Tomato plants, belonging to the Solanaceae family, and cucumber, melon, and watermelon plants, belonging to the Cucurbitaceae family, have shown the most severe disease symptoms. Plant viruses constitute the major causal factor for the diseases. In the recent years, there has been a growing concern regarding disease damages and losses occurring in vegetable crop production. Conferring resistance to rootstocks and cross-protection strategies are newly implemented approaches that could alleviate tobamovirus disease spread in both solanaceous and cucurbitaceous crops. However, CGMMV-resistant sources of cucurbitaceous vegetable crops are scarce. Promoting the production of solanaceous vegetable crops genetically resistant to ToMMV and ToBRFV infection is a promising approach. Practicing hygiene by plant growers and in nurseries is currently the main strategy for mitigation of tobamoviral infection. ![]() Mechanical plant injury suffices to initiate viral infection. These viruses adhere to agricultural facilities, contaminate the soil, infect seeds, and spread via beneficial pollinators and irrigation water. The primary route of tobamoviral infection is through mechanical means. Similarly, a recent widespread of the newly identified tobamoviruses, Tomato mottle mosaic virus (ToMMV) and Tomato brown rugose fruit virus (ToBRFV), has reduced the solanaceous crop production. The well-known tobamovirus Cucumber green mottle mosaic virus (CGMMV) has recently caused severe damages in the cucumber, melon, and watermelon cucurbitaceous crops, worldwide. The tobamoviruses are highly stable plant viruses that could cause severe disease symptoms. In the recent years, disease spread of old and newly evolved tobamoviruses has occurred worldwide, affecting production of various vegetable and ornamental crops. ![]()
