Evaluación de la técnica de amplificación por recombinasa y polimerasa (RPA) para la detección de begomovirus presentes en cultivos de soja y poroto en Argentina = Evaluation of the RPA technique for the detection of begomoviruses present in soybean and bean crops in Argentina
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2018)Los métodos tradicionales de diagnóstico son inespecíficos para la identificación de begomovirus. Actualmente se usan técnicas moleculares, que requieren equipamientos sofisticados o procedimientos complejos. La técnica de ... -
Evaluation of the behavior of common bean cultivars and promising lines under natural virus infection = Evaluación del comportamiento de cultivares y líneas experimentales de poroto común frente a infecciones naturales de virus
(Asociación Argentina de Horticultura, 2018)Las enfermedades virales pueden afectar la estabilidad de la producción de poroto común (Phaseolus vulgaris L.), por lo que es de interés evaluar el comportamiento de diferentes cultivares y líneas avanzadas del programa ... -
Evidence for contemporary plant mitoviruses
(2018-05)Mitoviruses have small RNA(+) genomes, replicate in mitochondria, and have been shown to infect only fungi to date. For this report, sequences that appear to represent nearly complete plant mitovirus genomes were recovered ... -
Evidence of cassava common mosaic virus in cassava shoot apical meristems
(Wiley, 2023-05-12)Cassava (Manihot esculenta) is an allogamous and highly heterozygous species. For this reason, its seeds are not used for production purposes (Ceballos & de la Cruz, 2002); instead, plantations are established using stem ... -
