Abstract
A TYPICAL smut life cycle has three phases—diploid, haploid, and dikaryon1. Diploid spores (teliospores) formed in the host tissue are a resting phase. They undergo meiosis at germination to form haploid vegetative cells which are usually yeast-like. The dikaryon is the pathogenic phase and is made up of cells with two haploid nuclei. It is initiated by the fusion of two compatible non-pathogenic haploid cells and the formation of an infection hypha by the fusion product.
