El lulo es uno de los renglones agrícolas más promisorios para la región andina Colombia, gracias a sus excelentes características organolépticas y su potencial el procesamiento industrial. En Antioquia, se ha observado en últimos años presencia plantas con síntomas enfermedades virales, que incluyen amarillamientos intervenales, mosaicos deformación brotes. este trabajo, evaluó dicha situación un grupo (bulk) muestras foliares sintomáticas obtenidas municipios del Oriente Antioqueño,...
Physalis peruviana L. is a herbaceous solanaceous plant native to the South American Andes that produces small yellow fruit of about 1-2 cm in diameter with high demand international markets. Currently, Colombia largest worldwide exporter this crop but, due emergence several phytosanitary problems, yields have experienced steady declined recent years. Viruses are not included current disease management programs P. evidence suggest viruses might play an important role decreasing productivity...
Due to the increase of international demand for functional fruits, cape gooseberry (Physalis peruviana) has become one crops highest expansion in Colombia and Andean region South America. nfortunately, emergence fungal unidentified viral diseases slowed down cultivation and, particularly, department Antioquia. In this work, a next-generation sequencing virome analysis plants from eastern Antioquia was performed, using leaves exhibiting symptoms such as mosaics, leaf deformation greening...
Las enfermedades virales son uno de los principales problemas fitopatológicos la papa. Con el fin determinar virus más prevalentes en cultivos papa var. Diacol Capiro oriente Antioqueño (Colombia), se evaluó mediante RT-qPCR presencia diez ARN (PVY, PVA, PVV, TaLMV, PVS, PLRV, PYVV, PVX, ToRSV y PMTV) 36 muestras tejido foliar. Los resultados indicaron ocurrencia cinco evaluados, con niveles prevalencia 88,9 %, 75 41,7 % 25 para PVY, PLRV respectivamente. fines comparativos, cuatro también...
Purple passion fruit, one of the most important fruit exports in Colombia, has been seriously affected recent years by several viral diseases. The aim present study was to investigate virome asymptomatic purple samples from commercial plots and nurseries Antioquia (Colombia). presence viruses first tested high-throughput sequencing (HTS) bulked leaf using total RNA dsRNA inputs. Interestingly, HTS data suggested a new badnavirus with genome 6,951 bp, which confirmed DNA rolling circle...
The productivity of potato in Colombia is far from its full potential mainly due to the high prevalence viruses seed-tubers. To gain a deeper insight into health status S. tuberosum and phureja seed-tubers used by farmers province Antioquia (Colombia), we have investigated PVY, PVV, PVS, PVX, PRLV, PYVV, PMTV PVB certified uncertified seed lots. presence was determined RT-qPCR, RT-PCR, Sanger High-Throughput Sequencing (HTS). eight were detected at least one lot sample or for most viruses,...
Viral diseases are one of the most limiting factors in production potato worldwide and their spread can be facilitated with use uncertified seed tubers. In developing countries, only a minority farmers has access to certified seeds, instead, great majority uses tubers from previous crops or purchase them local markets at lower cost. Successive cycles vegetative propagation these informal seeds result progressive decrease quality due accumulation pathogens pests. this work, we investigated...
Purple passion fruit is one of the most important crops in Colombia, but unfortunately, viral diseases have started to affect its productivity. Five viruses are known infect this crop Colombia: Soybean mosaic virus (SMV), Cowpea aphid-borne (CABMV), Passion yellow (PFYMV), Cucumber (CMV), and tentative species Gulupa bacilliform A (GBVA). In addition, emerging caused by begomoviruses were reported on other Passiflora Colombia. The incidence these adult plants, plantlets, seeds from...
Abstract Viruses are the causal agent of some most limiting diseases in Rubus crops. In this regard, a detailed knowledge virome is essential for successfully implementing mitigation strategies and assessing risk emergence novel viral diseases. Fortunately, widespread use RNA sequencing to characterize diverse aspects biology species can also be valuable source data on viruses associated with these hosts. Here, we present meta-analysis based re-examination public RNAseq from nine 23 hybrid...
La papa (Solanum tuberosum) es uno de los productos agrícolas con mayor demanda interna en Colombia. Este cultivo afectado por un complejo virus que reduce rendimientos y la calidad tubérculos-semilla. En este trabajo se evaluó prevalencia cinco ARN (PVY, PVS, PVX, PLRV PYVV) brotes tubérculos-semilla origen comercial (TC) no-comercial (TNC) sus plantas derivadas, utilizando RT-PCR tiempo real. Los resultados evidenciaron altos niveles infección el material siembra e infecciones mixtas hasta...
Cape gooseberry (Physalis peruviana) is one of the most important crops in Antioquia (Colombia). However, little known about viruses circulating southwestern region province. In this work, prevalence seven (PVY, PVS, PVX, TaLMV, PhyVNV, CGIV-1, and PMTV) was tested by RT-qPCR on seed samples, symptomatic asymptomatic plants from commercial fields region, virus genomes were investigated using high-throughput sequencing (HTS). The results showed detection all at least sample. PMTV prevalent as...
La papa criolla (Solanum phureja Juz. & Bukasov) es uno de los principales productos agrícolas la región Andina Colombia. Su siembra ocurre principalmente en pequeñas parcelas con deficiencias técnicas y bajos rendimientos. Las enfermedades origen viral son una las limitantes este cultivo, siendo virus PYVV, PVS, PLRV PVV algunos más importantes. El nivel conocimiento que se tiene del viroma Colombia incipiente. En estudio utilizando moleculares como secuenciación alto rendimiento (HTS)...
La gulupa (Passiflora edulisf. edulis) es uno de los frutales con mayor crecimiento en últimos años y gran influencia la economía Antioquia (Colombia); sin embargo, su cultivo afectado por diferentes problemas fitosanitarios, especialmente marchitez Fusariumoxysporumyenfermedades virales. En este estudio se evaluóla prevalencia cuatro virus ARN (SMV, CABMV, PFYMV CMV) mediante RT-qPCR, del género Begomovirusy badnavirus GBVA PCR, a partir muestras sintomáticas (SI) asintomáticas (AS)...
The productivity of potato in Colombia is below its potential due to continued agronomical malpractices that have resulted a high prevalence pathogens, particularly viruses. This work presents pilot virus seed-indexing study using the tuber sprouting test (TST) with RT-qPCR. TST was performed certified and uncertified seed-tuber lots cultivars: Diacol Capiro Criolla Colombia. Results indicate PYVV PMTV are highly prevalent all seed from both cultivars; PLRV, PVY, PVB cv. Capiro, but mostly...
Purple passion fruit is one of the most important exports Colombia, but its productivity being compromised by emergence several viral diseases. High-throughput sequencing (HTS) surveys viruses in purple fields province Antioquia suggested infection a new member family Tymoviridae. In this work, we characterize complete genome sequence virus, tentatively named passionfruit leaf deformation virus (PpLDV), and evaluate distribution Antioquia. PpLDV was assembled at high coverage four datasets...
El Potato virus Y (PVY) es uno de los más limitantes para la producción papa (Solanum tuberosum y S. phureja) en el mundo. Este transmitido por tubérculo-semilla diferentes especies áfidos. Para su manejo fundamental siembra tubérculos certificados sanidad viral, lo que se requieren metodologías detección altamente sensibles como ELISA RT-PCR. éstas últimas pruebas, necesario disponer cebadores específicos permitan diagnóstico del tejidos asintomáticos.
