<p>En noviembre de 1995, en los Municipios de Andes, Venecia e Hispania (Antioquia), La Tebaida y Montenegro (Quindío), se observaron hojas de plantas del don Dominico-Hartón (Musa AAB Simmonds) con rayas cloróticas y necróticas, síntomas que caracterizan la enfermedad del rayado del banano. En ocasiones las plantas presentaban síntomas de mosaico en el pseudotallo y el engrosamiento y/o rompimiento de la base del mismo. Además, en las cercanías de las plantaciones de plátano de los Municipios de Andes y Montenegro, se observaron respectivamente plantas de caña de azúcar (Saccharum officinarum) con síntomas de clorosis y de achira (Canna edulis) con síntomas de mosaico leve en sus hojas. Muestras de tejido foliar de éstas tres especies de plantas fueron analizadas para detectar la presencia del badnavirus del rayado del banano (BSV) y del virus del mosaico del pepino (CMV), mediante la prueba serológica DAS-ELISA, empleando anticuerpos policlonales comerciales (AGDIA Inc., Elkhart, IN). En el caso del plátano, en la región de Antioquia únicamente se detectó el BSV en el so% de las plantas sintomáticas analizadas, mientras que en el Quindío, el 6oo/o de las plantas estuvieron infectadas simultáneamente por BSV y CMV. El BSV se detectó también en muestras de tejido foliar de caña de azúcar y achira, pero en ningún caso resultaron positivas para el CMV, según la prueba DAS-ELISA. El análisis mediante microscopía electrónica de immunoabsorbancia (ISEM) del tejido foliar de plátano y caña de azúcar infectado, indicó la presencia de partículas baciliformes típicas del BSV de aproximadamente 30 x 110 nm. Hasta donde conocemos, este es el primer reporte sobre la presencia del BSV afectando plátano, caña de azúcar y achira en Colombia y es la primera vez que se reporta a la achira como hospedero de éste virus en el mundo.</p><p><strong><br /></strong></p><p><strong>First Report of Banana Streak Virus (BSV) Infecting Plantain (Musa AAB Simmonds), Sugar cane (Sacharumofficinarum) and Achira (Canna edulis) in Colombia</strong></p><p>Viruslike symptoms of yellow striate mosaic to necrotic streaks were observed on plantain leaves of the cultivar Dominico-Hartón (Musa AAB Simmonds) in the municipalities of Andes, Venecia and Hispania (Antioquia) and Tebaida and Montenegro (Quindío), Colombia. Symptoms sometimes included mosaic and swelling at the base of the pseudostem. Furthermore, in the neighborhood of the plantain crops, at the localities of Andes and Montenegro, it was observed respectively plants of sugarcane (Saccharum officinarum L.) with chlorotic foliar tissue and of achira (Canna edulis L.) with symptoms of mild mosaic in their leaves. The foliar tissue of symptomatic plants of these three species, was tested for banana streak virus (BSV ) and cucumber mosaic virus (CMV ) by double antibody sandwich enzime-linked immunosorbent assay (DAS-ELISA) with commercial polyclonal antisera (Agdia Inc., Elkhart, IN). BSV was detected in samples of all plant species. In Plantain, so% of the examined plants from the Antioquia region were infected by BSV, but not CMV; whereas, at the Quindío region, 6o% of the plants were simultaneously infected by both viruses, as detected by DAS- ELISA. CMV was not detected in foliar tissue of either sugarcane or achira plants. Immunosorbent electron microscopy analysis (ISEM) of BSV infected foliar tissue of plantain and sugarcane, showed the presence of viral bacilliform particles measuring ca. 30 x 110 nm, typical of BSV. Up to our knowledge, this is the first report of BSV infecting Musa spp., Saccharum officinarum and Canna edulis in Colombia, and the first time that Canna edulis is reported as a host for this virus.</p>

Leaf Symptoms

Banana (Musa sapientam L.) is an economically important crop for both export and local consumption in Taiwan. Recently, leaf symptoms characteristic of banana streak disease (1) were found on banana cv. Mysore (AAB group) introduced from Australia in the germ plasm collection of the Taiwan Banana Research Institute. The citrus mealybug (Planococus citri) has been shown to transmit banana streak virus (BSV) but not banana bunchy top virus or cucumber mosaic virus (CMV) (2). When mealybugs were fed on leaves of diseased Mysore banana and transferred to healthy banana cv. Cavendish seedlings in a growth chamber, the latter developed fine chlorotic streaks characteristic of symptoms caused by BSV within 1 to 3 months. Some chlorotic streaks became necrotic. BSV was detected in diseased but not healthy leaves of Mysore and Cavendish bananas by polymerase chain reaction (PCR) with primer pairs of BSV provided by J. E. Thomas of Queensland Department of Primary Industries. Subsequently, fine chlorotic streaks were observed in leaves of Cavendish banana in several fields in southern Taiwan. Some of these diseased plants developed severe leaf necrosis, causing heart rot of spindle leaves characteristic of symptoms caused by CMV. Presence of BSV in these plants was verified by PCR assay. However, CMV was also detected by double antibody sandwich-enzyme-linked immunosorbent assay with a monoclonal antibody to CMV, indicating that these plants were simultaneously infected by both viruses. This is the first report of BSV infecting Musa spp. in Taiwan. References: (1) B. E. L. Lockhart. Phytopathology 76:995, 1986. (2) B. E. L. Lockhart. 1995 Food & Fertilizer Technol.

Saccharicoccus Sacchari

We have recently reported on the presence of banana streak virus (BSV) affecting plantains (Musa spp.) in Colombia (2). BSV is serologically related to sugarcane bacilliform virus and has been found to be transmitted by the pink mealybug (Saccharicoccus sacchari) from sugarcane to banana (1). In the vicinity of affected plantain crops in the localities of Andes (Antioquia) and Montenegro (Quindio), we observed sugarcane (Saccharum officinarum L.) plants with chlorotic streaks on their leaves, as well as arrowroot (Canna edulis Ker-Gawl.) plants with mild mosaic symptoms. The foliar tissue of symptomatic plants of these two species was tested for BSV and cucumber mosaic virus (CMV) by double antibody sandwich-enzyme-linked immunosorbent assay with commercial polyclonal antisera (Agdia Inc., Elkhart, IN). BSV was detected in samples of both plant species, whereas CMV was not detected in either one. Immunosorbent electron microscopy analysis of BSV-infected, symptomatic, foliar tissue of sugarcane showed the presence of viral-like bacilliform particles measuring approximately 150 × 30 nm, typical of BSV. This is the first report of BSV infecting Saccharum officinarum in Colombia and the first report of Canna edulis as a host for this virus. References: (1) B. E. L. Lockhart and L. J. C. Autrey.

The Impact

Prior to the introduction of highly resistant sugarcane varieties, Sugarcane streak virus (SSV) caused serious sugar yield losses in southern Africa. Recently, sugarcane plants with streak symptoms have been identified across South Africa. Unlike the characteristic fine stippling and streaking of SSV, the symptoms resembled the broader, elongated chlorotic lesions commonly observed in wild grasses infected with the related Maize streak virus (MSV). Importantly, these symptoms have been reported on a newly released South African sugarcane cultivar, N44 (resistant to SSV). Following a first report from southern KwaZulu-Natal, South Africa in February 2006, a survey in May 2007 identified numerous plants with identical symptoms in fields of cvs. N44, N27, and N36 across the entire South African sugarcane-growing region. Between 0.04 and 1.6% of the plants in infected fields had streak symptoms. Wild grass species with similar streaking symptoms were observed adjacent to one of these fields. Potted stalks collected from infected N44 plants germinated in a glasshouse exhibited streak symptoms within 10 days. Virus genomes were isolated and sequenced from a symptomatic N44 and Urochloa plantaginea plants collected from one of the surveyed fields (1). Phylogenetic analysis determined that while viruses from both plants closely resembled the South African maize-adapted MSV strain, MSV-A4 (>98.5% genome-wide sequence identity), they were only very distantly related to SSV (~65% identity; MSV-Sasri_S: EU152254; MSV-Sasri_G: EU152255). To our knowledge, this is the first confirmed report of maize-adapted MSV variants in sugarcane. In the 1980s, “MSV strains” were serologically identified in sugarcane plants exhibiting streak symptoms in Reunion and Mauritius, but these were not genetically characterized (2,3). There have been no subsequent reports on the impact of such MSV infections on sugarcane cultivation on these islands. Also, at least five MSV strains have now been described, only one of which, MSV-A, causes significant disease in maize and it is unknown which strain was responsible for sugarcane diseases on these islands in the 1980s (2,3). MSV-A infections could have serious implications for the South African sugar industry. Besides yield losses in infected plants due to stunting and reduced photosynthesis, the virus could be considerably more difficult to control than it is in maize because sugarcane is vegetatively propagated and individual plants remain within fields for years rather than months. Moreover, there is a large MSV-A reservoir in maize and other grasses everywhere sugarcane is grown in southern Africa. References: (1) B. E. Owor et al. J Virol. Methods 140:100, 2007. (2) M. S.

Pcr Multiplex

Um protocolo de PCR multiplex foi estabelecido para a detecção do Banana streak virus (BSV) e do Cucumber mosaic virus (CMV) em bananeiras micropropagadas. Estes vírus são responsáveis por perdas na produção de bananas em todo o mundo. Alguns trabalhos descrevem a integração do BSV no genoma B da bananeira. Contudo, a existência de bananeiras híbridas livres do BSV tem sido demonstrada. Ademais, determinadas estirpes do CMV não são transmitidas mecanicamente sob condições de laboratório, nem tampouco detectadas por testes sorológicos. Como conseqüência, a indexação de matrizes para cultura de tecido algumas vezes se mostra ineficiente. A metodologia apresentada neste trabalho sobrepõe esta dificuldade, pois se baseia na detecção do ácido nucléico viral presente em amostras foliares de bananeira. Na reação, foram usados os oligonucleotídeos BADNA 1A e BADNA 4, para a detecção do BSV, e "CMV senso" e "CMV antisenso" para a detecção do CMV. Após a eletroforese foi verificada a presença de dois fragmentos de DNA amplificados simultaneamente, um dos quais com 597 pb correspondente ao BSV e o outro, com 488 pb, correspondente ao CMV. Este resultado indica que o PCR multiplex pode ser utilizado como uma ferramenta adicional na indexação do BSV e do CMV em bananeiras propagadas por cultura de tecido.
