Molecular characterization of a phytoplasma of group 16SrIX related to `Ca. Phytoplasma phoenicium' in periwinkle in Brazil
Tropical Plant Pathology 37 (2), 130-135
Abstract: Periwinkle (Catharanthus roseus), a tropical perennial plant, was found to be infected by a phytoplasma. Plants exhibiting virescence, phyllody and variegation symptoms were collected in the states of Minas Gerais and São Paulo, Brazil. The phytoplasma was transmitted by grafting from an infected periwinkle plant to healthy plants and by dodder to a citrus plant. Phytoplasma isolates from periwinkle plants from Brazil had the 16S rDNA gene sequenced and were classified in the 16SrIX group, subgroup A, belonging to the `Candidatus P. phoenicium' species.
