“…E. quercicola was systematically found to be associated with flag-shoots. It has been suggested that oak powdery mildew can survive from one growing season to the next as resting mycelium or conidia within dormant buds (van Peeteren 1912;Neger 1915). Woodward et al (1929) and Kerling (1966) E. alphitoides E. quercicola observed the overwintering of mycelia in infested buds, from which malformed shoots developed in spring, the stem and leaves being covered with mycelium and conidia.…”

Niche partitioning of the genetic lineages of the oak powdery mildew complex

Recent molecular studies have shown that four genetic lineages, probably cryptic species, cause oak powdery mildew in Europe. We tested the hypothesis of niche differentiation between the two most frequent species (Erysiphe alphitoides and Erysiphe quercicola), by determining their relative prevalences at various times during the growing season. E. quercicola was strictly associated with the flag-shoot symptom in a 2-yr sampling campaign of 35 natural oak seedling populations. Additional sampling during Aug.eSep. in the same stands showed that E. alphitoides predominated in most (70 %) cases. Time-course monitoring of powdery mildew in two natural regenerating oak populations confirmed the inverse patterns of relative abundance for these two species in early and late season. The coexistence of these two closely related species may be due to the use of different strategies, resulting from a trade-off between overwintering (flag-shoots vs. chasmothecia) and late-season performance.
