Two sex loci are present in S. megalocarpus. The color coding indicates HMG-domain-encoding genes (red, sexM and sexP), those conserved in Mucoromycotina species (green, blue, or brown), and those not associated with sex loci (gray). ψ, a pseudogene or fragment of a degenerated transposable element (Tn). The dark blue section of ψ rnhA indicates the inverted region within this pseudogene. Details about each of the genetic elements are provided in Table S1 in the supplemental material.
