Petite mutation be induced using a variety of mutagens, including DNA intercalating agents, as well as chemicals that can interfere with DNA synthesis in growing cells. Mutagens that create Petites are implicated in increased rates of degenerative diseases and in the aging process. A mutation that produces small (petite" > petite) anaerobic-like colonies had shown first in Yeast Saccharomyces cerevisiae and described by Boris Ephrussi and his co-workers in 1949 in Gif-sur-Yvette, France.
