V r. 2013 dvě nezávislé skupiny osekvenovaly kompletní genomy obou taxonomicky známých druhů latimérií (Latimeria). Článek krátce shrnuje celou historii jejich objevu, zeměpisné rozšíření a stručně podává přehled vývoji poznatků o jednotlivých částech jejich genomu. Poté komentuje výsledky zmíněných celogenomových studií zejména vzhledem ke dvěma skupinám genů – společné pro paprskoploutvé ryby (Actinopterygii) a latimérii a společné pro latimérii a čtvernožce (Tetrapoda).

Two independent research groups decipher the complete genomes of both taxonomically known species of the genus Latimeria. This note briefly summarizes the discovery and geographic distribution of coelacanth species, and overviews the history of findings dealing with various parts of their genomes. It also comments on the results of both whole genome sequencing studies, especially as regards two gene groups – those present in ray-finned fishes (Actinopterygii) and coelacanth and those present in coelacanth and tetrapods.
