The researchers think these epimutations could be employed in a variety of situations, enabling an organism to adapt to an unfavorable environment and then adapt again when conditions improve. Though they have only shown epimutations in two species of M. circinelloides, they have already been approached by a number of other researchers who are interested in investigating similar unstable behavior in other organisms like Aspergillus and Neurospora.

"It could be like the discovery of other molecular phenomena like introns or microRNAs, where it all began with just one example," said Heitman. "We think this discovery may turn out to be generalized fairly quickly."
