| Abstract: | Leaf curl in Zinnia elegans was observed in a subtemperate region in northern India, and the causal organism was identified as Ageratum enation virus (AEV). The virus appeared to be monopartite and associated with nanovirus-like satellite DNA1. The whole genome was amplified
by rolling circle amplification, cloned, and sequenced using a primer walking strategy. The genome (FN543099) was composed
of 2753 nucleotides (nt) and that of DNA1 (FN543100) of 1374 nt. DNA-β was not detected from any of the infected samples.
The study presents the first report of a begomovirus from Zinnia spp. in India and the complete nucleotide sequence characterization of AEV associated with nanovirus-like satellite DNA1. |
