Behavioural ecology: The social side of wild yeast
David C. Queller1
Abstract
The workhorse of cell biology, yeast, is a surprisingly cooperative organism. It uses an unusual means of identifying partners — a 'green-beard gene', which encodes a tag that must match among cooperating cells.
Everyone knows how a glass or two of beer can act as social glue, making even misanthropes amiable. Oddly, the production of beer has a similarly convivial effect on the tiny brewers that make it, cells of the yeast Saccharomyces cerevisiae.
