Here  we show that the teleost sinus venosus SV is a chamber like vessel comprised of an outer layer of smooth muscle cells. We find that in adult zebrafish nr2f1a mutants  which lack atria  the SV comes to physically resemble the thicker bulbus arteriosus BA at the arterial pole of the heart through an adaptive  hypertensive response involving smooth muscle proliferation due to aberrant hemodynamic flow. Single cell transcriptomics show that smooth muscle and endothelial cell populations within the adapting SV also take on arterial signatures. Bulk transcriptomics of the blood sinuses flanking the tunicate heart reinforce a model of greater equivalency in ancestral chordate BA and SV precursors. Our data simultaneously reveal that secondary complications from congenital heart defects can develop in adult zebrafish similar to those in humans and that the foundation of equivalency between flanking auxiliary vessels may remain latent within basal vertebrate hearts.

Therefore  we treated them as single end libraries by choosing read1 or read2 to match the strand as much as possible  and batch correction was applied as described below. Only uniquely aligned reads were retained for downstream analysis. Gene expression levels were quantified as raw read counts using FeatureCounts in the subread package with an option  \u201c O   fracOverlap 0.8\u201d  and with a proper strand option  s. Given the mixed sequencing batches and library types  we incorporated RUVseq batch correction RUVs  k=1 in DESeq2 differential analysis. Differentially expressed genes were identified by FDR < 0.05. Hierarchical clustering was performed using the Pearson correlation coefficient as a similarity measure under Ward\u2019s criterion  and a heatmap was visualized in z score.
