Molecular detection of peronospora variabilis in quinoa seed and phylogeny of the quinoa downy mildew pathogen in South America and the United States Idiomas
Testen, A. L., Jiménez-Gasco, M. M., Ochoa, J. B., and Backman, P. A. 2014. Molecular detection of Peronospora variabilis in quinoa seed and phylogeny of the quinoa downy mildew pathogen in South America and the United States. Phytopathology 104:379-386. Quinoa (Chenopodium quinoa) is an important export of the Andean region, and its key disease is quinoa downy mildew, caused by Peronospora variabilis. P. variabilis oospores can be seedborne and rapid methods to detect seedborne P. variabilis have not been developed. In this research, a polymerase chain reaction (PCR)-based detection method was developed to detect seedborne P. variabilis and a sequencing-based method was used to validate the PCR-based method. P. variabilis was detected in 31 of 33 quinoa seed lots using the PCR-based method and in 32 of 33 quinoa seed lots using the sequencing-based method.
