Aphelenchoides besseyi Christie (Nematoda: Aphelenchoididae), agente causal del amachamiento del frijol común

Abstract

[ES] La identificación del agente causal del amachamiento se llevó a cabo de diciembre de 2008 a noviembre de 2009 mediante cuatro pruebas: análisis para detectar ARN de doble cadena (dsRNA) de origen viral, DAS-ELISA, cumplimiento de los postulados de Koch y prueba de patogenicidad. El análisis para la detección de dsRNA reveló la presencia de dos bandas de aproximadamente 1100 y 3200 pb, coincidentes en tamaño para un miembro del género Bromovirus, aunque no se pudo establecer su asociación con el amachamiento debido a que ese patrón de bandas solo se presentó en el 55,5% de las muestras de plantas enfermas analizadas. Mediante la prueba de DASELISA no se detectó el Cowpea chlorotic mottle virus (CCMV) en ninguna de las muestras de plantas con amachamiento analizadas lo que confirma que ese virus no es causante de la enfermedad. La aplicación de los postulados de Koch y la prueba de patogenicidad permitieron identificar al nematodo Aphelenchoides besseyi Christie como el agente causal del amachamiento; asimismo, descartar a otros organismos patógenos mencionados previamente como agentes causales del amachamiento (CCMV o fitoplasma)

[EN] Identification of the causal agent of the disease “amachamiento” of common bean was carried out using four tests: analysis of double strand RNA (dsRNA) of viral origin, DAS-ELISA technique, applying Koch’s postulates and the pathogenicity test. The analysis to detect dsRNA brought about two bands of approximately 1100 and 3200 bp, a similar pattern of bands for a member of genus Bromovirus. However, those bands were present only in 55.5% of the diseased plant samples analyzed; consequently, it was not possible to establish an association of a virus with the disease. The DAS-ELISA test did not detected Cowpea chlorotic mottle virus (CCMV) in any samples of diseased plants, confirming that the causal agent of the disease is not this virus. By using both Koch’s postulates and the pathogenicity test, the nematode Aphelenchoides besseyi Christie was identified as the real causal agent of the bean disease “amachamiento” and we were able to discard other pathogen organisms previously proposed as responsible for the disease (CCMV and phytoplasm)
