Characterization of alphasatellites associated with monopartite begomovirus/betasatellite complexes in Yunnan, China.

ABSTRACT:

Background

Alphasatellites are single-stranded molecules that are associated with monopartite begomovirus/betasatellite complexes.

Results

Alphasatellites were identified in begomovirus-infected plant samples in Yunnan, China. All samples that contained alphasatellites also contained betasatellites, but only some samples that contained betasatellites contained alphasatellites. Thirty-three alphasatellites were sequenced, and they ranged from 1360 to 1376 nucleotides. All alphasatellites contain 3 conserved features: a single open reading frame (Rep), a conserved hairpin structure, and an adenine-rich (A-rich) region. On the basis of the phylogenetic tree of the complete nucleotide sequences, the alphasatellites were divided into 3 types with one exception. Type 1 was associa
