SEXUAL HORMONES IN ACHLYA

Sexual Hormones in Achlya

The sexual reproductive process of Achlya ambisexualis, a heterothallic form belonging to a well known and widely distributed genus of saprophytic aquatic fungi, is initiated and coordinated by means of specific substances (Raper, 1939, a).

Sebocytes express very little of the key enzyme, cytochrome P450c17, necessar...
