“…A horticultura ornamental apresentou um marcante crescimento nos últimos 40 anos, atingindo proporções substanciais e gerando grande interesse de produtores e investidores em todos os continentes (MALTER 1996). O setor de floricultura do Estado de São Paulo, em 2001, foi responsável por 70% do um bilhão de reais movimentados pelo mercado varejista brasileiro de plantas ornamentais; montante que se aproxima ao de outras culturas tradicionalmente relevantes como café, feijão e tomate para mesa.…”

RESUMONo período de 1992 a 2003 foi investigada, visando diagnóstico, a presença de vírus, viróides, fitoplasmas e espiroplasmas em 167 gêneros de plantas ornamentais, pertencentes a 64 famílias. Para o diagnóstico e a identificação desses patógenos, foram realizados ensaios biológicos, serológicos e/ou moleculares, bem como observações ao microscópio eletrônico de transmissão. Tospovirus foram detectados em 104 amostras pertencentes a 15 gêneros, incluindo flores de corte, envasadas e folhagens; Potyviridae estavam presentes em 23 gêneros, dentre esses Hyppeastrum, Lilium, Gladiolus e Dieffenbachia infectados com Potyvirus; Cucumovirus (Cucumber mosaic virus) e Ilarvirus foram detectados em 14 e 5 gêneros, respectivamente; Tobamovirus e Potexvirus, que são de ocorrência freqüente no Brasil, infectaram 40,4% das orquídeas que representaram 29,3% do total de amostras recebidas; outros 7 gêneros (Badnavirus, Carlavirus, Caulimovirus, Furovirus, Nepovirus, Tobravirus e Tymovirus) e duas famílias (Closteroviridae e Rhabdoviridae) de fitovírus foram também detectados. Nesse período, pelo menos três novas espécies de vírus foram descritas infectando crisântemo, petúnia e caládio. Viróide foi detectado em crisântemo, fitoplasma em lisiantos e espiroplasma em prímula. ABSTRACT Virus, viroid, phytoplasm and spiroplasm detected in ornamental plants from 1992 to 2003At the Laboratório de Fitovirologia e Fisiopatologia (Instituto Biológico), a total of 167 genera of ornamental plants belonging to 64 families were investigated, from 1992 to 2003, for the presence of virus, viroid, phytoplasm and spiroplasm caused diseases. The diagnosis and identification of the viruses were carried out by means of biological, serological and molecular assays as well as electron transmission microscopy. Tospovirus were detected in 104 samples belonging to 15 genera including cut and potted flowers along with foliage plants; Potyviridae species were present in 23 genera, among which Hyppeastrum, Lilium, Gladiolus and Dieffenbachia were infected by Potyvirus; Cucumovirus (Cucumber mosaic virus) and Ilarvirus infected 14 and 5 genera, respectively; Tobamovirus and Potexvirus, which are the two most frequent viruses in Brazil, were found in 40.4% of the orchids which represented 29.3% of the ornamental plants analised; another 7 genera (Badnavirus, Carlavirus, Caulimovirus, Furovirus and Nepovirus, Tobravirus, Tymovirus) and two families (Closteroviridae and Rhabdoviridae) of plant viruses were also detected. In this period, at least three new virus species were described in chrysanthemum, petunia and caladium. Viroid was detected in chrysanthemum, phytoplasm in lisianthus and spiroplasm in primula.

Aim. To summarise and analyse scientific data on Cucumber mosaic virus strains (CMV – Cucumber mosaic virus) (Martellivirales: Bromoviridae, Cucumovirus) isolated from ornamental plants in the Far East of the Russian Federation. Discussion. The paper describes the genome structure and tripartite organization of CMV virions. Strains of this virus isolated from ornamental cultures in the south of the Russian Far East are described: Garden balsam, Common snapdragon, Dahlias, Hybrid gladiolus, Hybrid delphinium, Cambria, Indian canna, Cattleya, Tiger lily, Garden petunia, Primula obconica, Moth orchids, Fatshedera from Lize Freres, Weeping fig, Common hollyhock, Purple coneflower. The physicochemical properties (i. e. point of thermal inactivation, period of preservation of infectivity at a temperature of 20 °C, maximum dilution of juice causing disease of healthy plants) and the symptoms of these strains on a wide range of species and varieties of indicator plants are systematised according to the Russian Collection of East Asian Viruses, functioning at the Laboratory of Virology of the Federal Scientific Center for East Asia Terrestrial Biodiversity, Far Eastern Branch, Russian Academy of Sciences. Conclusions. The limiting factor in the development of floriculture is infectious diseases, among which viral infections (including CMV) are of the greatest importance, demonstrating a high strain diversity in the south of the Russian Far East. Thus, the study of the biological, physico‐chemical, immunochemical and molecular biological properties of CMV is an urgent task, as it opens up the possibility of studying isolates of this virus and classifying its strains taking into account individual characteristics and kinship relationships.
