Life beyond 6,000 genes: From sequence to synthesis in a post-genomics era

Abstract The publication of the Saccharomyces cerevisiae genome sequence thirty years ago marked a defining shift in modern biology, establishing yeast as the first fully sequenced eukaryotic model cell. Access to a complete reference genome has catalysed a renaissance in experimental biology, providing the foundation for advances in functional genomics, systems biology, synthetic biology, and biotechnology. This article celebrates the achievements of the yeast sequencing project and highlights how genomics has evolved from a descriptive resource into a central enabling infrastructure for engineering biology, leading to a post-genomic era defined by genome-scale design. We chart the progression from decoding the genome to the omics revolution, highlighting both recent discoveries and persistent enigmas surrounding the ‘dark matter’ of the yeast genome. We then describe how access to a well-annotated reference genome has culminated in a new era of synthetic genomics exemplified by the Sc2.0 project. Finally, we explore how emerging trends in artificial intelligence and bioelectronics may shape the next thirty years of yeast genomics and engineering biology. This integration of past achievements and future trajectories reinforces the enduring role of S. cerevisiae as a primary eukaryotic model for biological discovery and biotechnological innovation.
