Abstract

An isolate (TK) from a virus-infected Tropaeolum majus specimen found on the island of Korcula (Jugoslavia) was investigated for purpose of identification. The virus was identified as an isolate of turnip mosaic virus (TuMV) on the basis on the following results:
Isolate TK caused only local lesions in N. tabacum cvs. “White Burley” and “Xanthi”-nc and C. quinoa, local lesions and sporadic systemic symptoms in C. amar anticolor, as well as systemic symptoms in N. glutinosa and B. rapa var. rapa. Infected N. glutinosa and B. rapa var. rapa plants contained elongated flexuous particles with an average length of 728 nm. Isolate TK gave a positive serological reaction with the antiserum to TuMV. It provoked the building of cytoplasmic inclusion bodies composed of a great number of needle-shaped crystals which are characteristic of TuMV. Thermal inactivation point of isolate TK was between 52° and 54° C. Isolate TK may belong to the ordinary strain of TuMV. This is the first finding of TuMV in a non-cruciferous species in Jugoslavia.
Infective sap of N. glutinosa contained occasionally tubular structures of submicroscopic dimensions.
The paper contains literature data on occurrence of TuMV in non- cruciferous plants, on spontaneous infections of T. majus with viruses, and data on the viruses which have been experimentally transmitted to T. majus.
