Occurrence of Agropyron Mosaic Virus in Britain.

Agropyron mosaic virus has been found in Britain for the first time. It was transmitted by the criophyid mite, Abacarus hystrix to wheat, and by sap-inoculation to 17 other festucoid species of Gramineae. The virus had flexuous, filamentous particles c. 715 × 15 am and was serologically related to a Canadian isolate. Many pinwheel and crystalline inclusions occurred in the cells of infected plants.
