    Notizen: A virus, code-named 52V, was obtained from 16 cultivars and seedlings of red raspberry by inoculation of sap to Chenopodium quinoa during spring or autumn. Some raspberry plants were infected with 52V after six months in the field, and more than 50 per cent of the plants of some cultivars were infected after four years. The virus was also obtained from Rubus occidentalis plants previously infected with virus from red raspberry by means of aphids (Amphorophora rubi and Aulacorthum solani). These aphids transmitted 52V from red raspberry to C. quinoa.52V was transmitted by inoculation of sap to six herbaceous species but induced symptoms only in Chenopodiaceae. In C. quinoa sap, 52V lost infectivity after dilution to 10−2, heating for 10 min at 52·5°C, storage at 18°C for 24 hr or treatment with n-butanol to 8·5 per cent (v/v). Preparations made by clarifying extracts with chloroform or ether followed by differential centrifugation contained a few isometric particles c. 30 nm in diameter which may be those of the virus.

    Notizen: Treatment of soil in October 1963 with 60 1b (a.i.)/acre (67⋅3 kg/ha) quintozene or 400 1b acre (448⋅4 kg/ha) D-D killed more than 95 per cent of the Longidorus elongatus present and largely prevented transmission of raspberry ringspot and tomato black ring viruses to ‘Red-gauntlet’ strawberry planted in April 1964. The herbicide chloroxuron at 5 1b (a.i)/acre (5⋅6 kg/ha) did not affect L. elongatus numbers but delayed infection of the strawberry plants by controlling weed sources of virus. Quintozene and D-D increased fruit yields four to six-fold in 1965 and nine to twelve-fold in 1966; chloroxuron caused only small increases. Quintozene persisted in the soil for several years but was not detected in strawberry fruit. In an experiment on virus-free soil, quintozene had no effect on ‘Talisman’ strawberry or ‘Mailing Jewel’ raspberry, but adversely affected growth of ‘Lloyd George’ raspberry and sugar beet. L. elongatus migrated slowly through soil and congregated in the root zone of strawberry plants. Populations in untreated plots increased about two-fold per year. Eggs were laid from April to July.

    Notizen: Summary Parsnip yellow fleck and rice tungro spherical viruses, with monopartite ss RNA genomes, resemble picornaviruses in the polymerase and NTP-binding domains of their encoded polyproteins. Though in separate genera, they may comprise a new family.

    Notizen: Summary Raspberry bushy dwarf virus (RBDV) has an unusual combination of properties and has been classified as the sole member of a new plant virus genus, for which the name idaeovirus has been proposed. Particles of RBDV resemble those of ilarviruses (familyBromoviridae) in appearance and in being transmitted in association with pollen. RBDV has two genomic RNA species, RNA-1 (5 449 nt) and RNA-2 (2 231 nt). The particles also contain RNA-3 (946 nt), a subgenomic monocistronic coat protein mRNA which is derived from the 3′ end of the bicistronic RNA-2. The single 190 K protein encoded by RNA-1 contains methyltransferase, helicase and polymerase domains. Evolutionary distance data obtained from multiple alignments of the amino acid sequence of the RBDV 190 K protein and corresponding proteins with replicative function from other plant viruses suggest that the closest affinities of RBDV are with the tripartite genomed viruses in the familyBromoviridae. We propose that the genus idaeovirus be included in the familyBromoviridae.
