Figure Lengend Snippet: Mitochondrial genome organization and transcriptional activity in T. penetrans . A) A circular plot depicting the genomic organization of the complete mitochondrial genome of human parasite, Tunga penetrans . The mitochondrial genome encodes 13 protein coding genes, 22 transfer RNAs and 2 ribosomal RNA genes, along with a replication origin. Genes are color-coded by functional category and transcribed in clockwise (outer circle) or counterclockwise (inner circle) directions. The genome’s organization and gene order are conserved relative to other Siphonaptera species. B) RNA-Seq read coverage across the mitochondrial genome of T. penetrans . The coverage plot highlights regions of high transcriptional activity, particularly in the large ribosomal RNA subunit ( rrnL ) and cytochrome c oxidase genes ( cox1-cox3 ). RNA-Seq reads were mapped to the mitochondrial genome to validate and refine the assembly, ensuring accuracy in gene annotation. The red line indicates number of sequences from the nanopore reads that mapped back to the genome.
