Potato Culture

Beet western yellows virus (BWYV) was isolated from potato cultivars showing leaf roll in Tasmania. Twenty-four of 25 plants representing 11 cultivars selected from the field as showing typical leaf roll symptoms contained virus that infected Capsella bursa-pastoris. Serological tests with two isolates showed them to be closely related to several Californian BWYV isolates. Because of strict plant quarantine and certification schemes operating in Tasmania since the early 1930s, these isolates of BWYV are probably representative of leaf roll isolates that were common before world-wide certification schemes. The occurrence of BWYV in potatoes during these early periods strongly indicates a world-wide significance of BWYV in potato culture. The wide spread occurrence of BWYV associated with leaf roll in Tasmanian potatoes could have very important consequences for the potato certification scheme. These are discussed together with the use of sensitive serological tests to detect luteoviruses in potato and facilitate their control.

An isolate of beet western yellows virus (BWYV) from lettuce in Tasmania was propagated in shepherd's purse, purified, and used to produce an antiserum in a rabbit. The lettuce isolate and the antiserum to it reacted similarly to the Californian type isolate from radish and its antiserum in double antibody sandwich enzyme-linked immunosorbent assays (DAS-ELISA). The Tasmanian DAS-ELISA system was used to confirm the presence of BWYV in a range of plant species from the southern mainland states of Australia, from the North Island of New Zealand and from central Mexico. Leaf tissue containing BWYV remained serologically reactive for long periods after the tissue was desiccated either by freeze-drying, air-drying or drying over silica gel. Bean leaf roll, potato leaf roll and soybean dwarf viruses were clearly distinct from BWYV and from each other in DAS-ELISA.

Leaf Virus

A range of crop plants, pasture legumes and weeds, mostly with yellows symptoms similar to those caused by luteoviruses, were collected from the field around Tasmania and checked for infection with beet western yellows virus (BWYV) and subterranean clover red leaf virus (SCRLV) using aphids and indicator plants. BWYV was recovered from 216 of 897 plants tested, representing 30 different species and including 16 not previously recorded as natural hosts. SCRLV was recovered from 163 of 637 plants, representing twelve species including four not previously recorded as natural hosts. BWYV was isolated most often from composites and crucifers, while SCRLV was recovered most frequently from legumes. Eight plants were found infected with both viruses together. In host range studies, Tasmanian isolates of BWYV caused symptoms in lettuce, subterranean clover and sugar beet like those seen on these plants in the field from which the virus was isolated, and were thus similar to isolates of BWYV from North America. The Tasmanian isolates of BWYV were also closely related serologically to Californian isolates of BWYV; these were serologically quite distinct from isolates of SCRLV, and both these groups were serologically distinct from legume yellows virus and from potato leaf roll virus.
