Transcriptomes of tissues of the razor clam Sinonovacula constricta

The razor clam Sinonovacula constricta (Lamarck 1818) is a famous marine bivalve species that widely distributed along the western Pacific coast with important economical and nutritional values. During the evolution, S. constricta has formed specific biological features to adapt to its living habit. To clarify the underlying molecular mechanism in forming the specific biological features, the tissues of siphon, gill, labial palp, foot, mantle, and intestine of S. constricta were subjected to RNA-sequencing. The results showed significant differences existed in gene expression among different tissues, which provided a molecular framework for understanding the differentiation of S. constricta tissues and their underlying specific biological functions. Overall design: The tissues of siphon, gill, labial palp, foot, mantle, and intestine were collected from healthy adult S. constricta (65.23 mm × 22.78 mm, shell length × shell width). Each sample was triplicated, and derived form a mixture from three individuals. After RNA extraction, the samples were subjected to Pacific Biosciences RS sequencing instrument for RNA-sequencing (Novogene Bioinformatics Technology Co., Ltd, Beijing, China).
