Natural infection of Alternanthera tenella (Amaranthaceae) by a new potyvirus

Abstract

A virus was isolated from joyweed ( Alternanthera tenella Colla-Amaranthaceae), a common weed in tropical and sub-tropical regions. Examination by electron microscopy showed long flexuous particles with an average length of 756 nm in crude sap. Serological results showed positive reaction with antisera to PVY-O. A fragment of 1772 nucleotides was sequenced. The CP sequence shares 76% of identity with the CP of Potato virus Y strain NTN. These results confirm that the virus is a new potyvirus infecting A. tenella , and the name Alternanthera mild mosaic virus (AltMMV) is proposed.
