Primer sequences used for qPCR experiments.

The primer sets were designed based on sequences from cloned genes (clone) or from transcriptome data (transcriptome). If from cloned genes, the corresponding GenBank accession number is provided in the table. If from transcriptome data, the sequences were retrieved by BLAST searches using as templates the annotated mRNA sequences from the sea urchin Strongylocentrotus purpuratus and subsequently validated by reciprocal BLAST against the NCBI GenBank database. The accession number of the corresponding NCBI sequence is provided in the table. Abbreviations: P. lividus, Paracentrotus lividus; L. variegatus, Lytechinus variegatus; H. erythrogramma, Heliocidaris erythrogramma. (XLSX)
