Yeast biology is the study of yeast, a type of fungi that is widely used in biological research and industry. Yeast, particularly the species Saccharomyces cerevisiae, is a model organism that has been extensively studied due to its simple genetics, rapid growth rate, and ease of manipulation in the laboratory. Research in yeast biology encompasses a wide range of topics, including cell cycle regulation, gene expression, metabolism, and stress response mechanisms. Yeast is also used as a model system to study various human diseases, including cancer and neurodegenerative disorders. Additionally, yeast is crucial for industrial applications such as fermentation in the production of bread, beer, and wine.
