Production of protease isozymes by Aphanomyces cochlioides and Aphanomyces euteiches

Physiological and Molecular Plant Pathology, 2004
The production of protease activity by the sugarbeet pathogen Aphanomyces cochlioides, the legume pathogen A. euteiches, and the fish pathogen Saprolegnia parasitica was examined. Protease activity was readily detected in supernatants of water cultures of each organism using autoclaved host tissue as a nutrient source.

Natural variation of Medicago truncatula resistance to Aphanomyces euteiches

European Journal of Plant Pathology, 2012
We analysed the resistance variation in 14 natural populations of Medicago truncatula from Tunisia to Aphanomyces euteiches infection. The reaction of M. truncatula lines to A. euteiches infection varied from susceptibility to full resistance. Of the overall level of phenotypic variation, 65.4 % was found to occur within populations.

Evaluation of the forma specialis concept in Aphanomyces euteiches

Mycological Research, 1991
One hundred and fifty-seven isolates of Aphanomyces euteiches were collected for comparison of morphology and pathogenicity. Pea, alfalfa or snapbean were used as baits for 140 isolates, 17 were collected using other crop and weed species. Isolates were tested for pathogenicity to seedlings of pea, alfalfa, snapbean, red clover and sugarbeet, and ...

Variability in Virulence ofAphanomyces euteiches

Plant Disease, 1991
Host specificity of Aphanomyces euteiches was studied with 14 isolates from throughout the United States and Canada. Isolates were obtained by baiting from soil samples and by direct recovery from roots of field-grown plants. At least one of the 14 isolates of A.

SOME FACTORS AFFECTING GROWTH OF APHANOMYCES EUTEICHES IN SYNTHETIC MEDIA

American Journal of Botany, 1960
Papavizas, G. C., and C. B. Davey. (USDA, ARS, Crops Research Division, Beltsville, Maryland.) Some factors affecting growth of Aphanomyces euteiches in synthetic media. Amer. Jour. Bot. 47(9) : 758–765. Illus. 1960.—Some nutritional requirements of 3 single‐zoospore isolates of Aphanomyces euteiches Drechsler were studied in a synthetic medium (SM‐1 ...

Reaction of Red Clover toAphanomyces euteiches

Plant Disease, 1992
Aphanomyces euteiches is an economically important root rot pathogen of pea (Pisum sativum). Red clover (Trifolium pratense) is known to be a host but expresses low susceptiblity to A. eutiches. Recently, an isolate (Ae-572) of A. euteiches was observed to be highly virulent on red clover.

Seed treatment of peas with fosetyl-Al against Aphanomyces euteiches

Netherlands Journal of Plant Pathology, 1990
In 1983, seed dressing of peas with fosetyl-Al (Aliette) compared favourably with all other treatments on a field heavily contaminated with foot and root rot pathogens. Experiments carried out in 1983 and 1984 could not establish the reason for this phenomenon.

Quantification of Aphanomyces euteiches in pea roots using specific fatty acids

Mycological Research, 2000
The fatty acid composition of pea roots with and without the root pathogen Aphanomyces euteiches was studied using whole cell fatty acids (WCFA), phospholipid fatty acids (PLFA) and neutral lipid fatty acids (NLFA). Initial screening for A. euteiches markers using WCFA analysis showed that the fatty acids 14:1·9, 14:0, 20:4 and 20:5 were specific to ...

Targeted CRISPR-Cas9-based gene knockouts in Aphanomyces euteiches

2023
Oomycete genome editing using CRISPR/Cas9 system represents the most promising and powerful technique to study genes involved in pathogenicity such as effectors. However, most of the reported successful studies have been obtained on Phytophthora sp.
