New potyvirus on Alstroemeria sp.

In the USA a new potyvirus has been characterized from Alstroemeria sp. which caused leaf streaking and necrosis and might induce considerable damage to alstroemeria cultivations. Transmission electron microscopy of crude leaf extracts revealed the presence of 780 nm long x 12 nm wide flexious rods. ELISA tests showed that the purified virus reacted strongly with a potyvitus specific antiserum.

Based on cytopathological studies, particle morphology and serology the authors assigned the virus to the potyvirus group and distinguished it from the alstroemeria mosaic potyvirus since it could not be transmitted mechanically to other host plants.

The authors provisionally named this virus 'alstroemeria streak potyvirus'.
