Furthermore, although enrichment of RNAs with mitochondrial functions among the Leotiomyceta Puf3 targets was highly significant ( Fig 4B , odds-ratio = 3.9, p = 10 −25 by Fisher's exact test), and the overlap with Saccharomycotina Puf3 targets was also significant (13%, odds-ratio = 3.2, p = 10 −6 by Fisher's exact test), the Leotiomyceta Puf3 target set included only 26 of the 202 Saccharomycotina Puf3 targets that have orthologs in N . crassa and included 87 mitochondrial targets not observed in Saccharomycotina.
