title: Nanovirus-like DNA component associated with the Malvastrum yellow mosaic virus.
abstract: Nanovirus-like DNA components signed DNA1 are single-stranded molecules associated with monopartite begomovirus-satellite complexes. DNA1 molecules ranging in size from 1373-1385 nucleotides were detected in 5 isolates Hn36, Hn38, Hn39, Hn44, and Hn45 of Malvastrum yellow mosaic virus (MalYMV) isolated in Hainan, China. DNA1 molecules of all isolates contained three characteristics: a single ORF, conserved hairpin structure, and A-rich region. Nucleotide sequence comparison showed that DNA1 molecules of 5 examined isolates shared high sequence identity (71.8-98.8%). In comparison with other begomovirus DNA1 and nanovirus-associated DNA, the sequence identities 59.6-76.3% and 27.2-38.4%, respectively, were found.
