A Study of Wheat Roots Infected with Ophiobolus Graminis (Sacc.) Using Fluorescence and Electron Microscopy

Abstract

Virus-like symptoms were observed on leaves of frangipani (Plurneria acutifolia Poir.) from several gardens in South Australia and New South Wales. The leaves showed chlorotic ringspots or mosaic and were often distorted (Fig. 1). As far as we are aware no viruses from frangipani have been previously isolated. This communica-tion is concerned with the isolation and characterization of an unusual strain of tobacco mosaic virus (TMV) from frangipani.
