Conidia induce the formation of protoperithecia in Neurospora crassa: further characterization of white collar mutants

Abstract

The treatment of undifferentiated mycelia with heavy suspensions of their own conidia triggers protoperithecial development. This effect was also observed with white collar (wc) mutants and suggests that the wc genes are not structural genes necessary for morphogenesis of protoperithecia but that they are probably involved in regulation.
