Context: Researchers from Indiana University conducted an experiment using a synthetically designed minimal cell containing only essential genes for survival to understand how such a cell would evolve under evolutionary forces.
- They used a synthetic version of Mycoplasma mycoides, a microbe commonly found in the guts of goats and cattle, creating a stripped-down minimal cell (JCVI-syn3.B) with only 493 genes.
- Despite the minimal cell’s reduced fitness and sickness due to genome minimization, the researchers found that it could evolve as fast as a normal cell.
The minimal cells evolved differently from non-minimal cells, and the study shed light on microbial evolution and the potential of synthetic organisms in synthetic biology applications. The findings show that even organisms with minimal genomes can evolve and adapt effectively, providing valuable insights into evolutionary processes.
