Abstract EN
Genes without introns are a characteristic feature of prokaryotes, but there are still a number of intronless genes in eukaryotes.
To study these eukaryotic genes that have prokaryotic architecture could help to understand the evolutionary patterns of related genes and genomes.
Our analyses revealed a number of intronless genes that reside in 6 deuterostomes (sea urchin, sea squirt, zebrafish, chicken, platypus, and human).
We also determined the conservation for each intronless gene in archaea, bacteria, fungi, plants, metazoans, and other eukaryotes.
Proportions of intronless genes that are inherited from the common ancestor of archaea, bacteria, and eukaryotes in these species were consistent with their phylogenetic positions, with more proportions of ancient intronless genes residing in more primitive species.
In these species, intronless genes belong to different cellular roles and gene ontology (GO) categories, and some of these functions are very basic.
Part of intronless genes is derived from other intronless genes or multiexon genes in each species.
In conclusion, we showed that a varying number and proportion of intronless genes reside in these 6 deuterostomes, and some of them function importantly.
These genes are good candidates for subsequent functional and evolutionary analyses specifically.
