Tissues-specific transcriptome of Strongylocentrotus intermedius was sequenced for the first time.
In total 96,764 contigs within 24,778 gene families in S. intermedius were annotated.
Potential tissue-specific pathways progressed in different tissues were annotated.
In S. intermedius, 1074 (4.3% of all genes) genes were annotated as defending genes.
Coelomocytes is the main immune monitor, complement is very important in S. intermedius.
