Volatile Sexual Hormones in Mucor mucedo Mesland, D. A. M. and Huisman, J. G. and Van Den Ende, H.,, 80, 111-117 (1974), doi = https://doi.org/10.1099/00221287-80-1-111, publicationName = Microbiology Society, issn = 1350-0872, abstract= SUMMARY: A special technique permitted observation of sexual reactions between mycelia of Mucor mucedo without diffusion contact via the substrate. Morphogenetic phenomena (zygophore formation) appeared to be induced by volatile substances in a sex-specific way. Zygophores, induced via the air, showed chemotropic activity. The volatile stimuli were partly purified by thin-layer chromatography and appeared to have the same RF values as precursors of trisporic acids. Trisporic acids are currently assumed to be responsible for the induction of zygophore formation via the substrate., language=, type=
