| Resumo: |
Catharanthus roseus is a perennial, evergreen herb in the family Apocynaceae, which is used as ornamental and for popular medicine to treat a wide assortment of human diseases. This paper describes a new potyvirus found causing mosaic symptom, foliar malformation and flower variegation in C. roseus. Of 28 test-plants inoculated mechanically with this potyvirus, only C. roseus and Nicotiana benthamiana developed systemic mosaic, whereas Chenopodium amaranticolor and C. quinoa exhibited chlorotic local lesions. The virus was transmitted by Aphis gossypii and Myzus nicotianae. When the nucleotide sequence of the CP gene (768nt) was compared with other members of the Potyviridae family, the highest identities varied from 67 to 76 %. For the 3' UTR (286nt), identities varied from 16.8 to 28.6 %. The name Catharanthus mosaic virus (CatMV) is proposed for this new potyvirus.
