| a mosaic disease of senna hirsuta induced by a potyvirus in nigeria. | a virus inducing mosaic and severe leaf malformation, isolated from senna hirsuta in nigeria, was studied. the virus had a rather narrow host range, infecting a few species in caesalpinaceae, chenopodiaceae and fabaceae families. the virus was widespread in southern nigeria with prevalence ranging from 74% to 86.4% in some locations. it was transmitted mechanically and in a non-persistent manner by myzuspersicae, aphis craccivora and a. spiraecola. there was no evidence of transmission by seeds. ... | 2001 | 11719985 |
| biological and molecular characterization of a putative new potexvirus infecting senna occidentalis. | in this work, we report the complete genome sequence of, production of polyclonal antibodies against, and development of biological assays for a putative new potexvirus, named senna mosaic virus (senmv), found infecting senna occidentalis in the state of são paulo, brazil. the complete genome sequence of senmv comprises 6775 nucleotides excluding the poly(a) tail. the genome organization is similar to those of other potexviruses, with five open reading frames coding for rna-dependent rna polymer ... | 2017 | 27796545 |
