Figure 3 in The complete mitochondrial genome of the mackerel icefish, Champsocephalus gunnari (Actinopterygii: Channichthyidae), with reference to the evolution of mitochondrial genomes in Antarctic notothenioids
Figure 3. Map of the mackerel icefish mitochondrial (mt) genome as a circular diagram. The map represents the mt genome of a type-1 individual in which ND6 and tRNAGlu were transposed to a position between tRNAThr and tRNAPro flanked by intergenic spacers (UN3 and UN4), and the ND6- to -CR segment was duplicated once. Fourteen protein-coding genes, two rRNA genes, and noncoding regions are labelled with abbreviations. Twenty-four tRNA genes are shown by a one-letter amino acid code. Different codons used by each of tRNALeu and tRNASer are shown in parentheses. Genes transcribed from the heavy strand and light strand are respectively presented outside and inside the circle. Heavy- and light-strand replication origins are represented by OH and OL, respectively. Abbreviations: 12S, 12S ribosomal RNA; 16S, 16S ribosomal RNA; A, tRNAAla; ATP, ATP synthase; C, tRNACys; CO, cytochrome oxidase; Cyt b, cytochrome b; D, tRNAAsp; E, tRNAGlu; F, tRNAPhe; G, tRNAGly; H, tRNAHis; I, tRNAIle; K, tRNALys; L, tRNALeu; M, tRNAMet; N, tRNAAsn; ND, nicotiamide adenine dinucleotide (reduced form) dehydrogenase; P, tRNAPro; Q, tRNAGln; R, tRNAArg; S, tRNASer; T, tRNAThr; V, tRNAVal; W, tRNATrp; Y, tRNATyr.
Data for: Three amphioxus reference genomes reveal gene and chromosome evolution of chordates
<p><span>The slow-evolving invertebrate amphioxus has an irreplaceable role in advancing our understanding into vertebrate origin and innovations. Here we resolve the nearly complete chromosomal genomes of three amphioxus species, one of which best recapitulates the 17 chordate ancestor linkage groups. We reconstruct the fusions, retention, or rearrangements between descendants of whole genome duplications (WGDs), which gave rise to the extant microchromosomes that likely existed in the vertebrate ancestor. Similar to vertebrates, the amphioxus genome gradually establishes its 3D chromatin architecture at the onset of zygotic activation and forms two topologically associated domains at the <em>Hox</em> gene cluster. We find that all three amphioxus species have ZW sex chromosomes with little sequence differentiation, and their putative sex-determining regions are nonhomologous to each other. Our results illuminate the unappreciated interspecific diversity and developmental dynamics of amphioxus genomes and provide high-quality references for understanding the mechanisms of chordate functional genome evolution.</span></p>
Fig. 1 in The mitochondrial genomes of ladybird beetles and implications for evolution and phylogeny
Fig. 1. Organizational maps of the 13 new mitogenomes sequenced in this study. Genes labelled above the line are transcribed in the same direction from left to right, while genes labelled below the line are transcribed in the same direction from right to left. The genes and intergenic spacers are scaled to their length in the mitogenome.
