Operons (clusters of co-regulated genes with related functions) are common features of
bacterial genomes. More recently, functional gene clustering has been reported in …

Trans‐splicing is the joining together of portions of two separate pre‐mRNA molecules. The
two distinct categories of spliceosomal trans‐splicing are genic trans‐splicing, which joins …

Chaetognaths (arrow worms) are an enigmatic group of marine animals whose phylogenetic
position remains elusive, in part because they display a mix of developmental and …

The Viridiplantae (green plants) include land plants as well as the two distinct lineages of
green algae, chlorophytes and charophytes. Despite their critical importance for identifying …

Pre-RNA splicing is an essential step in generating mature mRNA. RNA trans-splicing
combines two separate pre-mRNA molecules to form a chimeric non-co-linear RNA, which …

Molecular markers for tracing animal sample origins and compositions are critical for
applications such as parasite detection, contamination screening, and sample …

The cryptochrome/photolyase (CRY/PL) family represents an ancient group of proteins
fulfilling two fundamental functions. While photolyases repair UV-induced DNA damages …

The origin of chordates has been debated for more than a century, with one key issue being
the emergence of the notochord. In vertebrates, the notochord develops by convergence …

The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan
and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws …

Lophotrochozoa is a protostome clade that includes disparate animals such as molluscs,
annelids, bryozoans, and flatworms, giving it the distinction of including the most body plans …
