Desarrollo de marcadores microsatélites y mitocondriales para estudios de variación genética de Spongospora subterranea f. sp. subterranea

Bioagro, 2013
Spongospora subterranea f.sp. subterranea (Sss), agente causal de la sarna polvosa de la papa, es uno de los patógenos más limitantes de este cultivo, al afectar el sistema radicular de las plantas y la calidad de los tubérculos.

No rest for resting spores: Can predators mitigate clubroot disease?

Journal of Sustainable Agriculture and Environment, Volume 2, Issue 2, Page 131-139, June 2023., 2023
Soil microbiome predators are key players in nutrient cycling and in shaping the microbiome. Their potential use as biocontrol agents remains mainly unexplored. Using clubroot disease of Brassica crops as an example, we review the potential direct and indirect impacts microbiome predators can have on soil‐borne plant diseases.

Development and validation of a novel rapid in vitro assay for determining resistance of potato cultivars to root attachment by Spongospora subterranea zoospores

Plant Pathology, Volume 72, Issue 2, Page 392-405, February 2023., 2023
We developed a novel rapid and robust in vitro assay for screening potato varietal resistance to Spongospora subterranea root attachment and infection. Abstract Spongospora subterranea f. sp. subterranea is a major pathogen of potatoes leading to losses in tuber quality and yield.

Towards biological control of Spongospora subterranea f. sp. subterranea, the causal agent of powdery scab in potato [PDF]

Australasian Plant Pathology, 2017
Powdery scab of potato, caused by the obligate biotrophic protozoan pathogen Spongospora subterranea f.sp. subterranea (Sss), is a major problem in potato growing areas throughout the world. It results in lesions (scabs) on the surface of the tubers which renders them unmarketable.

Eficiencia de dos consorcios bacterianos para el control de Spongospora subterranea f. sp. subterranea en cultivos de papa Solanum tuberosum var. andígena

Temas Agrarios, 2021
Para los cultivadores de papa, las plagas y enfermedades son los principales problemas que afectan la producción. Cultivos completos se pierden por la enfermedad llamada sarna polvorosa causada por el protozoo Spongospora subterranea f. sp. subterranea (

Powdery Scab of Potato Etiology, its Management through Chemical and Biological Methods [PDF]

Phytopathogenomics and Disease Control
Potato (Solanum tuberosum) production is significantly constrained by powdery scab, caused by Spongospora subterranea f. sp. subterranea (Sss), a soil-borne pathogen that also transmits Potato mop-top virus (PMTV).

Occurrence of Potato Powdery Scab Caused by Spongospora subterranea f. sp. subterranea in Costa Rica

Plant Disease, 2002
Powdery scab of potatoes, caused by Spongospora subterranea (Wallr.) Lagerheim f. sp. subterranea Tomlinson, is important worldwide due to its effect on tuber quality and transmission of Potato mop-top virus. Although powdery scab-like lesions have been observed on potato in Costa Rica (1), the presence of the pathogen has not been confirmed. During a

Pest categorisation of Synchytrium endobioticum

EFSA Journal, Volume 16, Issue 7, July 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of the fungus Synchytrium endobioticum, the causal agent of potato wart disease, for the European Union (EU). The identity of the pest is well established and reliable methods exist for its detection and identification. S. endobioticum is present in most continents.

Long‐Read Metabarcoding With Optimized Bioinformatic Analysis Outperforms Short‐Read Metabarcoding for Assessing Soil Protist Diversity and Ecology

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Comparing 18S metabarcoding of protist cultures and environmental samples with short and long read sequencing highlighted the advantages of each method. In particular, the study of 26 vineyard soil samples with long reads showed high potential and reliability for ecological research with an increased sensitivity to environmental patterns.
