An assessment of the transmission rate of Tomato black ring virus through tomato seeds
Plant Protection Science 56 (1), 9-12
Abstract: Tomato black ring virus (TBRV) infects a wide range of economically important plants, and is distributed worldwide. TBRV is transmitted by soil-inhabiting nematodes. However, a long-distance dispersion is possible via seeds and pollen. In this study, we provided evidence that virus can be efficiently transmitted through tomato seeds. Three tomato varieties (Beta Lux, Grace and Money Maker) and four genetically diverse TBRV isolates collected originally from different hosts were used in the experiments. The seedlings were grown in an insect-proof glasshouse and the presence of TBRV was verified by immunoassay (ELISA). The seed transmission was significantly dependent on tomato cultivar and virus isolate ranging from 1.69% up to 14.57%. Bioassays using Chenopodium quinoa plants confirmed the presence of infectious virus in the seeds.
