There was a mistake in Figure 4D as published. PK-2 sequence inside the box was displayed as “CACU” and the correct is “CAUU”. The corrected Figure 4D appears below.

Halobacterium salinarum circRNAs in IS200/IS605 transposases and their ωRNAs. (A) VNG_RS00170/VNG0044H (gray box) and its ωRNA (blue box) with the annotated circRNA, circRNA_0012 (red arc). Black triangles mark transcript processing sites (TPS) associated with the ωRNA (Ibrahim et al., 2021). Coordinates on top of the main chromosome (NC_002607.1), in base pairs. (B) VNG_RS104000/VNG02652H (gray box) and its ωRNA (blue box) with the annotated circRNA, circRNA_0397 (red arc). Coordinates on top of the main chromosome (NC_002607.1), in base pairs. (C) RNA structure of sot0044 ωRNA. Black triangles mark the TPS as in panel A. Red triangles mark the start and end of junctions in circRNA_0012. Helices are numbered as in Supplementary Figure S9. (D) RNA structure of sot2652 ωRNA. Red triangles mark the start and end of junctions in circRNA_0012. Helices are numbered as in Supplementary Figure S9. PK, pseudoknot; TEM, transposon encoded motif. (E) RT-PCR validation of circRNA_0397 associated with sot2652. The left panel is a reaction made with convergent primers expected to amplify both linear and circular templates. The middle panel is the reaction made with divergent primers expected to amplify only circular products. The right panel is made with primers that amplify a linear product that is digested by RNAse R. Blue arrows (left) indicate the expected linear product, while red arrows (right) indicate the expected bands for circRNA junction amplification. The uncropped image of the agarose gel is in Supplementary Figure S11.

Five-panel scientific figure showing genetic and molecular analyses. Panels A and B: gene diagrams display VNG_RS00170 and VNG_RS10400 with blue arrows for sot0044 and sot2652, genomic coordinates, and red arcs indicating specific regions. Panels C and D: RNA secondary structure models labeled PK-1 and PK-2, with boxed guide sequences, hairpin structures, and marked sites, including red arrowheads. Panel E: three gel electrophoresis images comparing gDNA, RNA, and RNAse R-treated samples; bands are marked with blue and red arrowheads to indicate relevant changes.
