Area of Science:

  • * Molecular Biology
  • * Genomics
  • * Microbiology

Background:

  • * Saccharomyces cerevisiae (baker's yeast) is crucial for biotechnology and a key model organism in biological research.
  • * It is the first eukaryote to have its complete genome sequenced.
  • * Genome sequencing provides a wealth of biological information but also highlights knowledge gaps.

Purpose of the Study:

  • * To analyze the implications of the complete genome sequence of Saccharomyces cerevisiae.
  • * To identify the proportion of yeast genes with unknown functions.
  • * To explore the potential of yeast as a model for post-genomic studies.

Main Methods:

  • * Analysis of the complete Saccharomyces cerevisiae genome sequence.
  • * Identification and characterization of gene functions.
  • * Assessment of the potential for large-scale reverse genetics.

Main Results:

  • * The complete genome sequence of Saccharomyces cerevisiae has been determined.
  • * A significant number of yeast genes are identified as 'orphan' genes with unpredictable functions.
  • * The study highlights the extensive remaining unknowns within a simple eukaryotic genome.

Conclusions:

  • * The sequencing of the yeast genome offers vast biological insights but reveals substantial gaps in functional understanding.
  • * Yeast serves as a powerful model for post-sequencing research, particularly for studying orphan genes.
  • * Future research faces the challenge of formulating novel questions to address the functional genomics of yeast.
