Sequence analyses of RT-PCR products obtained from seven infected leaf samples revealed existence of three potyvirus species in Indian narcissus (Narcissus tazetta L.).

Potyvirus species associated with yellow leaf stripe disease of Indian narcissus (Narcissus tazetta L.) var. Paperwhite has been studied by sequence analyses of ~ 1.5 kb genomic fragments obtained from seven RT-PCR amplifications of infected samples. Sequence analysis revealed the occurrence of three potyvirus species: cyrtanthus elatus virus-A (CEVA: KF430815, KF430816, KM066973, KM066974); narcissus yellow stripe virus (NYSV: KM066972, JQ686724) and narcissus degeneration virus (NDV: MK572806). The existence of three potyvirus species: CEVA, NYSV and NDV are being reported in Indian narcissus.
