The “mirror” capability of ballistospore-forming yeast species.

(A) The plate on the left was inoculated with Sporobolomyces sp. wild type strain IAM 13481, and inverted onto an uninoculated plate on the right. (B) Diagram of the steps in the formation of a ballistospore from a yeast cell, based on [2], [10]. (C) The 18 mirror mutants isolated in this study growing on the top plate (left) and their replication to a bottom plate (right). The wild type strain is in the top left hand corner of the bottom plate.
