Research performed in the yeast Saccharomyces cerevisiae has significantly improved our understanding of important cellular phenomona such as regulation of the cell cycle, aging, and cell death. The many benefits of working with S. cerevisiae include the facts that they are inexpensive to grow in the lab and that many ready-to-use strains are now commercially available. Nevertheless, proper maintenance of this organism is critical for successful experiments. This video will provide an overview...

Saccharomyces cerevisiae is a species of yeast that is an extremely valuable model organism. Importantly, S. cerevisiae is a unicellular eukaryote that undergoes many of the same biological processes as humans. This video provides an introduction to the yeast cell cycle, and explains how S. cerevisiae reproduces both asexually and sexually Yeast reproduce asexually through a process known as budding. In contrast, yeast sometimes participate in sexual reproduction, which is important because...

S. cerevisiae are unicellular eukaryotes that are a commonly-used model organism in biological research. In the course of their work, yeast researchers rely upon the fundamental technique of transformation (the uptake of foreign DNA by the cell) to control gene expression, induce genetic deletions, express recombinant proteins, and label subcellular structures. This video provides an overview of how and why yeast transformation is carried out in the lab. The important features of yeast...

Yeast Two-Hybrid Assay to Determine Protein Self-Association in Yeast Cells

2025
This video demonstrates the yeast two-hybrid assay to detect specific protein self-interactions. In this assay, the protein of interest is tagged to two domains of a transcription factor that encodes the β-galactosidase enzyme. When the two proteins interact, this causes transcription and translation to form the enzyme, which is then detected using a biochemical assay.

PCR-mediated gene modification can be used to generate fluorescent protein fusions in Candida species, which facilitates visualization and quantitation of yeast cells and proteins. Herein, we present a strategy for constructing a fluorescent protein fusion (Eno1-FP) in Candida parapsilosis.
FAQs
A species’ metabolism, physiology, and environmental tolerance help determine where it can thrive. Metabolism describes how it obtains and uses energy, while physiology includes functional characteristics that support growth. Together, these differences explain why yeast species occupy different environments and interact with surrounding organisms in distinct ways, making comparative biology important.
Yeast species can reproduce primarily by budding or by fission, providing a useful biological comparison. Because reproduction is connected with cell growth, examining the dominant pattern helps researchers investigate how yeast cells propagate and how reproductive strategies vary among fungi. This comparison also supports broader studies of cellular development and organismal diversity.
When oxygen is limited, many yeast species can obtain energy by fermenting sugars. This process produces ethanol and carbon dioxide, linking cellular metabolism to visible outcomes such as gas formation and alcohol production. Differences in metabolic behavior help explain why species vary in their usefulness for food production, biotechnology, and biological research.
Researchers can compare yeast species by examining cell growth, reproductive pattern, metabolism, physiology, and tolerance of environmental conditions. These characteristics reveal how species differ while supporting investigations of genetics and other eukaryotic processes. Such comparisons connect observable traits with underlying biological variation and help identify species suited to particular research questions.
Metabolism, growth-related physiology, and environmental tolerance are key considerations when yeast species are applied to baking, brewing, or biotechnology. Their ability to convert sugars into ethanol and carbon dioxide can support particular production goals, while species-level differences determine how well they perform under the conditions associated with a given application.
Saccharomyces cerevisiae serves both practical and scientific roles. It is used in baking, brewing, biotechnology, and the production of useful biological products, while also supporting studies of cell growth, genetics, and eukaryotic processes. Its importance therefore extends beyond one application, connecting fundamental biology with food production and industrial research.
