Host preference in isolates of Phytophthora infestans collected from potato and tomato crops in Colombia
The plant pathogen Phytophthora infestans is the causal agent of late blight disease in both potato (Solanum tuberosum) and tomato (Solanum lycopersicum) crops. Previous studies suggest that isolates of P. infestans present differences in their potato-tomato host preference. In Colombia, potato and...

| description |
The plant pathogen Phytophthora infestans is the causal agent of late blight disease in both potato (Solanum tuberosum) and tomato (Solanum lycopersicum) crops. Previous studies suggest that isolates of P. infestans present differences in their potato-tomato host preference. In Colombia, potato and tomato are economically important. Thus, it is important to determine if populations of P. infestans growing on potato may pose a risk to nearby tomato crops and vice versa. To achieve this, detached leaflets from one susceptible variety of potato (Diacol Capiro) and detached leaflets from one susceptible variety of tomato (Chonto Santa Cruz Kada), were inoculated with six isolates of P. infestans collected from potato and six isolates of P. infestans collected from tomato from different rural areas of Colombia. Two isolates from the United States, with known host preference, were used as controls. Lesion area and mean sporulation between the two hosts were determined seven days after inoculation for all isolates. Furthermore, the incubation period and latent period on potato and tomato were also evaluated. The results suggest that isolates that had been collected on potato could represent a risk for nearby tomato crops. However, most isolates that had been collected on tomato did not grow on potato. Information on the potato-tomato host preference of isolates of P. infestans in Colombia may be important for future field-management decisions |

Estudios previos sugieren que los aislamientos de P. infestans presentan diferencias en su preferencia de hospedero papa-tomate. En Colombia, la papa y el tomate son de importancia económica. Por lo tanto, es importante determinar si las poblaciones de P. infestans que crecen en la papa pueden representar un riesgo para los cultivos de tomate cercanos y viceversa. Para lograr esto, se inocularon hojas sanas provenientes de una variedad susceptible de papa (Diacol Capiro) y hojas sanas de una variedad susceptible de tomate (Chonto Santa Cruz Kada) con seis aislamientos de P. infestans recolectados de papa y seis aislados de P. Infestantes recogidos de tomate de diferentes zonas rurales de Colombia. Se utilizaron dos aislamientos de los Estados Unidos, con preferencia de hospedero conocida, como controles. El área de la lesión y la esporulación media entre los dos hospedadores se determinaron siete días después de la inoculación para todos los aislamientos. Además, también se evaluaron el período de incubación y el período de latencia en papa y tomate. Los resultados sugieren que los aislamientos que se habían recolectado en la papa podrían representar un riesgo para los cultivos de tomate cercanos. Sin embargo, la mayoría de los aislamientos que se habían recolectado en tomate no crecían en papa. La información sobre la preferencia de aislamientos de P. infestans en Colombia por el huésped de papa y tomate puede ser importante para futuras decisiones de manejo de campo."--Tomado del Formato de Documento de GradoMicrobiólogoPregrado23 hojasapplication/pdfengUniversidad de los AndesMicrobiologíaFacultad de CienciasDepartamento de Ciencias Biológicasinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaHost preference in isolates of Phytophthora infestans collected from potato and tomato crops in ColombiaTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPPhytophthora infestansPatología vegetalPapas (Tubérculos)TomatesPlantasMicrobiologíaPublicationc1d0400e-c8b1-47fa-a90b-0c76096cd8e3virtual::1931-1c1d0400e-c8b1-47fa-a90b-0c76096cd8e3virtual::1931-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001370823virtual::1931-1TEXTu820753.pdf.txtu820753.pdf.txtExtracted texttext/plain32274https://repositorio.uniandes.edu.co/bitstreams/155762a1-843e-4507-af83-7880639e75fc/downloadfeda6bfc06f93fdaa9b79d546afcc5b3MD54ORIGINALu820753.pdfapplication/pdf305304https://repositorio.uniandes.edu.co/bitstreams/adff2d02-01af-4cbd-b78a-605626d8da3d/downloadf79207012b19d90b858f9d651a735c74MD51THUMBNAILu820753.pdf.jpgu820753.pdf.jpgIM Thumbnailimage/jpeg20581https://repositorio.uniandes.edu.co/bitstreams/f2faba8f-15c9-4d45-88ed-61002597138d/downloadf24063d0fbaca5d1935937f72a5d21f2MD551992/38982oai:repositorio.uniandes.edu.co:1992/389822024-03-13 12:05:06.002http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
