3'-coterminal subgenomic RNAs and putative cis-acting elements of Grapevine leafroll-associated virus 3 reveals 'unique' features of gene expression strategy in the genus Ampelovirus.

ABSTRACT:

Background

The family Closteroviridae comprises genera with monopartite genomes, Closterovirus and Ampelovirus, and with bipartite and tripartite genomes, Crinivirus. By contrast to closteroviruses in the genera Closterovirus and Crinivirus, much less is known about the molecular biology of viruses in the genus Ampelovirus, although they cause serious diseases in agriculturally important perennial crops like grapevines, pineapple, cherries and plums.

Results

The gene expression and cis-acting elements of Grapevine leafroll-associated virus 3 (GLRaV-3; genus Ampelovirus) was examined and compared to that of other members of the family Closteroviridae. Six putative 3'-coterminal subgenomic (sg) RNAs were abundantly present in grapevine (Vitis vinifera) infected with GLRaV-3. T
