Sterol Induction of Reproduction and Stimulation of Growth of <i>Pythium</i> and <i>Phytophthora</i>

Abstract

Sterols of fungal, plant, and animal origin induced sexual reproduction in Pythium periplocum and Phytophthora megasperma var. sojae and the formation of large zoosporangia in Phytophthora parasitica var. nicotianae. Some sterols, especially cholesterol, stimulated growth.
