Sexual Reproduction• Fungal nuclei are normally haploid, with theexception of transient diploid stages formedduring the sexual life cycles• Sexual reproduction requires the fusion of<strong>hyphae</strong> from different mating types• Fungi use sexual signaling molecules calledpheromones to communicate their mating typeCopyright © 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
