Abstract
The complete genome sequence of Narcissus yellow stripe potyvirus (NYSV) isolated from Narcissus tazetta cv. Paperwhite exhibiting leaf chlorotic stripe symptoms was determined for the first time from India. The viral genome sequence contained 9650 nucleotides that encode a large polyprotein (372.36 kDa) of 3103 amino acids. The comparison of the NYSV genome sequences with corresponding sequences of other potyviruses revealed 90-97% identities and closest phylogenetic relationships with NYSV-Zhangzhou-1 and -ZZ-2 isolates infecting N. tazetta reported from China. Therefore, the NYSV isolate understudy was considered as a new member of NYSV and designated as NYSV-NAR2.
