Abstract

CHEMICAL regulation of sexual development in fungi was suggested in the 1880s by Sachs and de Bary (see ref. 1). Burgeff2 later demonstrated that the so-called + and − strains of Mucor mucedo if separated by a colloidion membrane, produced zygophores that grew toward each other. The presence of diffusible substances which function in the sexual cycle has since been demonstrated in, for example, Achlya1,3–8, Allomyces9,10, Ascobolus11–13, Mucor14–20, Saccharormyces21–23, and Neurospora24–27. Varied functions have been attributed to these extracts. In some well studied systems, such as Achlya and Mucor, chemical substances have been reported at almost all stages of sexual development, each serving to initiate the next stage4,17.
