GENETICS: Yeast as a Model Organism

Yeast as a Model Genetic Organism

The budding yeast Saccharomyces cerevisiae has emerged as a versatile and robust model system of eukaryotic genetics. Mutant screening and segregation analysis are simpler and easier to perform in yeast than in multicellular organisms; and fundamental eukaryotic biology, such as cell cycle control and alternation of generations, is wellconserved throughout eukaryotic taxa. Yeast has a high endo...

Chlamydomonas as a Model Organism.

The unicellular green alga Chlamydomonas offers a simple life cycle, easy isolation of mutants, and a growing array of tools and techniques for molecular genetic studies. Among the principal areas of current investigation using this model system are flagellar structure and function, genetics of basal bodies (centrioles), chloroplast biogenesis, photosynthesis, light perception, cell-cell recogn...

Introduction: C. elegans as a model organism

organism The nematode Caenorhabditis elegans is a genetically tractable multicellular organism that has been the subject of intense study for more than four decades. It has been successfully used as a model system to address fundamental questions in multiple fields of biology, including development, neurobiology and aging. In recent years, this tiny nematode worm has been applied to the study o...

Functional Analysis of Human Subtelomeric Breakage Motifs Using Yeast as a Model Organism

Yeast biofilm colony as an orchestrated multicellular organism

Although still often considered as simple unicellular organisms, in natural settings yeast cells tend to organize into intricate multicellular communities. Due to specific mechanisms only feasible at the population level, their capacity for social behavior is advantageous for their survival in a harmful environment. Feral Saccharomyces cerevisiae strains form complex structured colonies, which ...
