Resumo

Cathranthus roseus também conhecida como pervinca, planta ornamental contém vários valores medicinais, foi encontrada com poucos sintomas de folhas e vassouras de bruxa no local de Shahjahanpur, com incidência de até 8%. A etiologia do fitoplasma foi confirmada através do exame de microscopia eletrônica de varredura. Análises moleculares adicionais por meio de PCR aninhado, análise filogênica e silco RFLP confirmaram a associação do fitoplasma do subgrupo 16SrIX-C em pequenas plantas de folhas e vassouras de bruxa, que é o primeiro relatório da Índia.
