Untargeted metabolomic analysis reveals a potential role of saponins in the partial resistance of pea (Pisum sativum) against a root rot pathogen, Aphanomyces euteiches.

Phytopathology
In soil-borne diseases, the plant-pathogen interaction begins as soon as the seed germinates and develops into a seedling. Aphanomyces euteiches, an oomycete, stays dormant in soil and gets activated by sensing the host through chemical signals present ...

Aphanomyces root rot of cauliflower

Mycopathologia, 1977
A species of Aphanomyces De Bary was found inciting a destructive root rot disease of cauliflower (Brassica oleracea L. var. botrytis) and cabbage (Brassica oleracea L. var. capitata) in the heavy soil fields of Varanasi, U. P. The pathogen was isolated on corn meal agar and oat meal agar.

Characterization of Aphanomyces euteiches pathotypes infecting peas in Western Canada.

Plant Disease, 2021
Aphanomyces root rot, caused by the soil-borne oomycete Aphanomyces euteiches Drechs., has developed into a serious disease in the pea and lentil-producing areas of the Great Plains of North America.

Viability and maturation ofAphanomyces cochlioidesoospores

Mycologia, 2003
Plasmolysis, tetrazolium bromide staining and microscopic appearance were tested for their usefulness in determining viability of oospores of Aphanomyces cochlioides. For comparison, three lethal treatments were employed to contrast the reaction of dead oospores and untreated, presumably viable oospores.

APHANOMYCES PHYCOPHILUS IN CULTURE

American Journal of Botany, 1938
APHANOMYCES PHYCOPHILUS De Bary, one of the rarer Saprolegniales, was first described by DeBary in 1860 from a collection made at Frankfort am Main. Since then it has been reported from Michigan by Kauffman (1915), from Indiana by Weatherwax (1914), from New York by Sparrow (1933), and from North Carolina by Couch (1926).

Molecular characterization of Aphanomyces species associated with legumes

Mycological Research, 2004
The identification of plant-associated isolates of Aphanomyces spp. has been mainly based on morphological characters. These types of features, however, can be unreliable due to their high variation and degree of overlap between different taxa. In this work, strains of Aphanomyces, with plant pathogenic and non-pathogenic characteristics, derived ...

Distribution and abundance of Aphanomyces euteiches in agricultural soils: effect of land use type, soil properties, and crop management practices

Agriculture, Ecosystems & Environment. Applied Soil Ecology, 2020
Aphanomyces euteiches is a soil-borne pathogen that causes root rot in susceptible pulse crops. Although widespread across Canada, A. euteiches was not reported in Saskatchewan until 2012. The distribution of this pathogen across the Canadian prairies is
