Abstract

Microcyclic conidiogenesis (MC) was recently described in several species of powdery mildew fungi. This process, defined as the production of conidia on a fungal spore without any, or only a minimal, involvement of hyphal growth, was observed on powdery mildew conidia that have already germinated on host plant surfaces and have been attached to the epidermal cells. Most probably, MC contributes to a quick propagation of young powdery mildew colonies because new conidia are sometimes produced in a shorter time on microcyclic conidiophores than on the hyphae of the young mycelium. This article reports MC in Erysiphe necator ex grapevine, Podosphaera leucotricha ex apple, Golovinomyces orontii ex tobacco, and Neoerysiphe galeopsidis ex Lamium purpureum based on light and low-temperature scanning electron microscopic studies.
