The parasite chromosomes exhibit limited conservation of
gene synteny with Plasmodium falciparum, and its plastid - like genome represents the first example where all apicoplast genes are encoded on one DNA strand.
Comparative genomics analyses with uncultivated environmental TM7 assemblies show remarkable conserved
gene synteny and only minimal gene loss / gain that may have occurred as TM7x adapted to conditions within the human host.

To address these challenges, we generated a uniform reannotation of the protein - coding
genes for all avian genomes based on
synteny in chicken and zebra finch (SM2).
For ~ 13,000 (low - coverage genomes) to ~ 18,000 (high - coverage genomes) annotated
genes across avian species (44), phylomeDB inferred orthologs for 94.58 % of them and these agreed with the
synteny - based orthology of the 8251 protein - coding
genes of the TENT by 93 %.
Metazoans can now be defined by a long list of genomic synapomorphies —
gene content, intron — exon structure and
syntenies — as well as characteristics common to all animal life such as sex, development, controlled cellular proliferation, differentiation and growth, and immunity.
The organization of
genes shows conserved
synteny (that is, conserved linkage without necessarily requiring colinearity) relative to other animals.
In particular, 83 of the 153 longest Amphimedon scaffolds (those that contain
genes from more than ten distinct metazoan
gene families, sufficient for
synteny to be assessed) show segments of conserved
synteny with other animals (Supplementary Note 6).
