Yeast Cell Communication in Mating

Yeast cell communication helps control mating, colony growth, and other cell responses. Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes with a nucleus. Their signaling works much like cell signaling in other eukaryotic cells.

A signal often begins when a ligand, such ...

Single-celled eukaryotes, like yeasts, also communicate through cell-surface receptor proteins, similar to multicellular eukaryotes.

For example, during sexual reproduction, yeast cells form two haploid cell types called a and α mating types. Each type contains a single set of chromosomes.

Each mating type secretes specific mating fa...
