It is common among protists that the sexual cycle is inducible by stressful conditions such as starvation.Such conditions often cause DNA damage. A central feature of meiosis is homologous recombination between non-sister chromosomes. In T. thermophilia this process of meiotic recombination may be beneficial for repairing DNA damages caused by starvation.
