| Abstract: | Bell pepper mottle virus (BPeMV) can be distinguished by symptomatology and host range from other tobamoviruses but a reliable identification needs serological tests. The relationships of BPeMV to tobacco mosaic virus (TMV), Odontoglossum ringspot virus (ORSV), tobacco mild green mosaic virus (TMGMV), and pepper mild mottle virus (PMMV) were investigated using precipitin drop tests on slides, immunodiffusion gel tests, double antibody sandwich enzyme-linked immunosorbent assay (ELISA), and indirectELISA using enzyme-linked goat anti-rabbit globulins for the determination of antiserum titers and serological differentiation indices (SDI). Comparisons of SDIs and amino acid composition data demonstrated that BPeMV is a new species of the tobamovirusgroup. BPeMV, ORSV, PMMV, and TMGMV form a cluster within the genus (group) and could be considered as a subgenus of tobamoviruses. |
