Evolutionary biology: genomic clues to original sex in fungi.
Sexual identity in fungi is conferred by a diverse group of transcription factors. Analysis of a Zygomycota genome, representing a basal branch within the fungi, indicates that HMG-domain proteins were present as ancestral sex determinants and suggests a mechanism for the evolution of eukaryotic sex chromosomes.
