An unusual isolate of turnip mosaic potyvirus from Abutilon theophrasti in Piedmont, Italy
Phytoparasitica 28 (2), 149-152
Abstract: An isolate of the potyvirus turnip mosaic virus (TuMV-Ab) showing severe mosaic symptoms in Abutilon theophrasti from Piedmont (northwestern Italy) in 1993, has been found to be of an unusual pathotype and serotype. The isolate was easily transmitted by Aphyis gossiypii and Myzus persicae and was not seed-transmitted in A. theophrasti. The host range of TuMV-Ab was different from that of another Piedmont isolate of TuMV from Alliaria officinalis and from a TuMV isolate from Brassica napus. TuMV-Ab was characterized using the reactions on the four B. napus lines S4, R4, 165 and S1 as the rare pathotype 7, found only once previously in Europe. Tests with polyclonal antisera indicated that TuMV-Ab was only distantly related to the two other TuMV isolates. Serological characterization with a panel of 30 monoclonal antibodies showed that TuMV-Ab belonged to one of the less common serotypes (JPN).
