Annotated genomic loci and expression profiles of Hydractinia echinata H3.3.1 and H3.3.2. a H3.3.1 expression in feeding polyps and male and female sexual polyps. H3.3.1 is highly abundant in female germ cells (red wedge). The annotated genomic locus of H3.3.1 shows its coding sequence, mapped RNA reads (showing the number of reads mapped), a predicted TATA-box and a polyA signal. The gene contains two exons. b H3.3.1 expression is replication-independent and its transcripts do not co-localise with EdU-positive S-phase cells in both feeding polyps (red wedge in Bi) and male sexual polyps (white asterisk in Bii). Replicating cells do not contain H3.3.1 transcripts (yellow asterisk in Bii). c H3.3.2 expression in feeding polyps. The annotated genomic locus of H3.3.2 shows its coding sequence, mapped RNA reads (showing the number of reads mapped), a predicted TATA-box and a 3′-UTR stem-loop. The gene contains one exon. H3.3.2 expression is replication-dependent, and its transcripts co-localise with EdU-positive S-phase cells (red wedge)
