담배 품종 NC 82, 및 KF 114와 Datura stramonium, Physalis floridana, Gomphrena globosa, Chenopodium spp.를 이전에 조사한 검정식물에 추가하여 TMV Common Tomato 및 Pepper 계통으로 감염시켜 기주 반응을 조사하였다. TMV Common 계통에 전신감염되는 NC 82와 P. floridana는 Tomato와 Pepper 계통에 의해서는 다른 증상 즉 NC 82는 국부병반, P. floridana는 무병징을 보였으며, Common과 Tomato 계통에 의해 국부병반이 나타나는 KF 114와 G. globosa는 Pepper 계통이 감염되었을 때 아무런 증상도 나타나지 않았다. Tomato와 Pepper 계통에 의한 국부병반의 수와 크기는 Xanthi-nc 보다 KF 114에서 상대적으로 작았으나 Common 계통은 차이가 없었다. Common 계통에 감염된 Xanthi-nc와 KF 114는 고온에서 전신괴저 증상을 나타냈으나 다른 계통에 의해서는 이러한 증상이 발생하지 않았다.

Tobacco (Nicotiana tabacum) cultivars including NC 82 and KF 114, and Datura stramonium, Physalis floridana, Gomphrena globosa, and Chenopodium spp. were added to the previous host plants tested for the further examination on the biological characteristics of tobacco mosaic virus (TMV) strains isolated from tobacco (TMV-Common), tomato (TMV-Tomato), and pepper (TMV-Pepper). In TMV-Tomato and TMV-Pepper, different symptoms were noted in P. floridana (no symptom development), and NC 82 (local lesion production on the inoculated leaves) from TMV-Common with which systemic mosaic symptoms were developed. Local lesions were developed in KF 114, D. stramonium, G. globosa, and Chenopodium spp by TMV-Common and TMV-Tomato, while no symptom was observed in KF 114 and G. globosa. Also the number and size of local lesions were smaller in KF 114 than Xanthi-nc tobacco (local lesion host) infected with TMV-Tomato. Systemic necrosis was induced in Xanthi-nc and KF 114 when infected with TMV-C at high temperature, but not with the other strains.
