“…A low level of genetic diversity in A. euteiches populations was observed between the different locations in France, as shown by the moderate number of multilocus genotypes identified (13 different MLGs within 205 isolates) including a predominant MLG (MLG1) shared by 54% of the isolates studied. This result is consistent with previous studies conducted on French and American A. euteiches populations, using codominant or dominant markers (Malvick and Percich, 1998 ; Wicker, 2001 ; Grünwald and Hoheisel, 2006 ; Mieuzet et al, 2016 ; Le May et al, 2018 ). In this study, the similar level of differentiation observed within and among populations also confirmed the absence of a clear genetic structure, as previously reported (Malvick and Percich, 1998 ; Wicker et al, 2001 ; Grünwald and Hoheisel, 2006 ).…”

“…In France, a preliminary study of the genetic diversity using AFLP markers found unstructured populations among 56 pea A. euteiches isolates collected in infested fields (unpublished data). Recently, Mieuzet et al ( 2016 ) and Le May et al ( 2018 ) used SSR and Sequence Related Amplified Polymorphisms (SRAP) markers, respectively, to show the absence of genetic structure among French pea isolates sampled from research disease nurseries. However, in the same study, Le May also found significant genetic structure among American isolates sampled from four American nurseries.…”

“…Five strains of A. euteiches were used in this study. Three French strains (Rb84, C6, and B2) belonged to pathotype I (Le May et al, 2017), and two U.S. strains (MF1 and Ae109) belonged to pathotype III (Wicker, Hulle, & Rouxel, 2001). These five strains were isolated from infested peas and stored on a sterile Corn Meal Agar media at 10°C.…”

“…species including common bean, broad bean, faba bean, clover and alfalfa (Burnett, Coventry, Hirth, & Greenhalgh, 1994;Greenhalgh & Merriman, 1985;Lamari & Bernier, 1985;Moussart, Even, & Tivoli, 2008;Pfender & Hagedorn, 1982;Tivoli, Baranger, Sivasithamparam, & Barbetti, 2006). It is a phenotypically and genotypically heterogeneous species (Grünwald & Hoheisel, 2006;Malvick & Percich, 1997; Le May et al, 2017;Quillévéré-Hamard et al, 2018). Aphanomyces euteiches is a diploid and homothallic pathogen producing both oospores (sexual reproduction) and zoospores (asexual reproduction; Grünwald & Hoheisel, 2006).…”
