Animals are known to adjust their sexual behaviour depending on mate competition. Here
we report similar regulation for mating behaviour in a sexual unicellular eukaryote, the …

The handicap principle holds that costly sexual signals can reliably indicate mate quality.
Only individuals of high quality can afford a strong signal—the cost of signaling is relatively …

Yeast cells approach a mating partner by polarizing along a gradient of mating pheromones
that are secreted by cells of the opposite mating type. The Bar1 protease is secreted by a …

Many cells detect and follow gradients of chemical signals to perform their functions. Yeast
cells use gradients of extracellular pheromones to locate mating partners, providing a …

Sex with another species can be disastrous, especially for organisms that mate only once,
like yeast [1–3]. Courtship signals, including pheromones, often differ between species and …

Cells' ability to track chemical gradients is integral to many biological phenomena, including
fertilization, development, accessing nutrients, and combating infection. Mating of the yeast …

Evolution has resulted in numerous innovations that allow organisms to increase their
fitness by choosing particular mating partners, including secondary sexual characteristics …

The fundamental principle underlying sexual selection theory is that an allele conferring an
advantage in the competition for mates will spread through a population. Remarkably, this …

Yeast decode pheromone gradients to locate mating partners, providing a model for
chemotropism. How yeast polarize toward a single partner in crowded environments is …

The maintenance and detection of signaling gradients are critical for proper development
and cell migration. In single-cell organisms, gradient detection allows cells to orient toward a …
