| description | An investigation was initiated in 1998, to elucidate the etiology of two diseases of apparent viral nature in the southwestern African oil palm production region of Colombia. The ring spot disease was first observed in 1985, in the municipality of Tumaco, Nariño, causing a lethal disease of young (l-3 year-old) palms. Electron microscopy of diseased foliar tissue extracts revealed the presence of filamentous virus-like particles, ca. 800 nm in length. Double-stranded RNA ex tractions made from diseased palms, led to the cloning and partial sequencing of viral genome fragments showing amino acid sequence identities of 51-67% with the corresponding genes of the tentative foveavirus species Cherry green ringspot mottle virus and Cherry necrotic rusty mottle virus. Lower but consistent amino acid sequence identities (40-62%) were observed in comparisons with two recognized foveaviruses: Apple stem pitting virus and Rupestris stem pit ting-associated virus. The second disease, chlorotic ring , was first observed in 1996, also affecting young African oil palms in Tumaco. This disease is not lethal, but growers eliminate affected palms any way. The disease is caused by a different filamentous virus ca. 750 nm in length. The virus was characterized as a species of the genus Potyvirus, namely a strain of Sugarcane mosaic virus. Possible virus trans mission mechanisms and disease management practices are discussed here. |

En 1998 se inició una investigación para determinar la etiología a de dos enfermedades de aparente naturaleza viral, que afectan el cultivo de la palma africana de aceite en el suroccidente colombiano. La pre sencia de la mancha anular se registré por primera vez en 1985, en el municipio de Tumaco, Nariño, Esta enfermedad afecta palmas jóvenes en los primeros 1-3 años de vida. Las plantas afectadas mueren rápidamente debido a una necrosis sistémica. Esta enfermedad se asoció consistentemente a la presencia de un virus filamentoso de aproximadamente 800 nm de longitud y 15 nm de diámetro, con un genoma sencillo compuesto por una molécula de ARN de aproxima damente 8.000 nucleótidos. La caracterización molecular parcial del virus mostró identidades del 51-67% en la secuencia de aminoácidos con respecto al ORF 1 de dos especies tentativas del género Foveavirus: el Cherry green ringspot mottle virus y el Cherry necrotic rusty mottle virus. También se observaron identidades de secuencia de aminoácidos del 40-62% para la misma región, entre el virus de la palma africana de aceite y los foveavirus Apple stem pitting virus y Rupestris stem pitting-associated virus. La segunda enfermedad viral, el anillo clorótico , no es letal, pero las plantas sintomáticas son destruidas por los agricultores. Esta enfermedad se observó en 1996 en el municipio de Tumaco, afectando también palmas jóvenes. El anillo clorótico es causado por un virus filamentoso de aproximadamente 750 nm de longitud y 15 nm de diámetro, el cual induce inclusiones cilíndricas en el citoplasma de las células infectadas. El virus se transmìtió mecánicamente a especies de gramíneas (maíz, cala de azúcar, sorgo y braquiaria). Secuencias parciales del genoma viral demostraron homologías del 90.8-95% con cepas del Sugarcane mosaic virus. Se discuten aquí algunas estrategias de control. 2002 2014-10-02T08:33:34Z 2014-10-02T08:33:34Z Journal Article https://hdl.handle.net/10568/44301 es Open Access application/pdf |
