The first DNA 1-like α satellites in association with New World begomoviruses in natural infections
چکیده انگلیسی

From Brazilian weeds with typical symptoms of a geminivirus infection, the DNAs of two new virus species, two new strains with two variants of already known bipartite begomoviruses were sequenced. Moreover, the first two DNA 1-like satellites (α satellites) occurring naturally in the New World were identified. They are related to nanoviral DNA components and show a typical genome organization with one open reading frame coding potentially for a replication-associated protein (Rep), a conserved hairpin structure, and an A-rich region. After coinoculation with their helper begomoviruses (Euphorbia mosaic virus, EuMV or Cleome leaf crumple virus, ClLCrV) the satellite DNAs were transmitted to experimental and natural host plants. Three of the begomovirus isolates (EuMV and ClLCrV) infected Arabidopsis thaliana plants, induced mild symptoms, and one of these (ClLCrV) transreplicated the satellite efficiently. As a result, several novel tools for molecular analyses of this important model plant are provided.
