Yeast's lifestyle couples mating with meiosis

Mating and meiosis -- the specialized cell division that reduces the number of chromosomes in a cell -- are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, where the two programs work in unison, according to a new study. Comparison with other species suggests that this fusion may support C. lusitaniae's "haploid lifestyle" of maintaining only one set of chromosomes in each cell.
