ψND5-2 compensatory mutations. (A) Phylogenetic distributions of three ψND5-2 direct repeat sequence haplotypes among temperate and tropical-clade C. briggsae isolates are shown on top. Black lines indicate lineages that encode DRSeq1 (identical to downstream ND5 sequence), blue lines show lineage with DRSeq2 and red lines show DRSeq3-encoding lineages. Boostrap support (neighbor-joining over maximum parsimony) is shown for relevant nodes. Specific DNA sequence changes in DRSeq2 and DRSeq3 are shown on bottom. (B) Variation in ND5 heteroplasmic deletion frequencies among isolates encoding different ψND5-2 sequences is shown. Error bars show S. E. M. (C) Mean fecundities of isolates encoding different ψND5-2 sequences are shown. Error bars show S. E. M.
