Expression profiles of contigs similar to P24733, the myosin heavy chain of striated muscle in GigasDatabase version 6 (A) and the new alignement of these contigs in GigasDatabase version 8 (B). A. Fourteen probes similar to P24733 (Myosin Heavy Chain from Argopecten irradians) show the same profiles of transcript abundance (line) and appear more abundant in mantle (M), Muscle (MS) and Hemocytes (HE) than in other tissues, and two probes did not show significant variation of signal intensity among tissue samples (dots). For each biological sample, numbers identify the individuals (individuals 1 to 8), letters identify the tissues (GI: Gills; G: gonad; DG: Digestive gland; M: Mantle; MS: Adductor muscle; P: Labial palps; GG: Visceral ganglia; HE: Hemocytes), followed by m for males (individuals 1, 7 and 8) and f for females (individuals 2, 3, 5 and 6). a, b, c and d correspond to pools of 6 individuals necessary to extract a sufficient amount of RNA for both visceral ganglia and hemocyte samples. B. The 16 contigs similar to P24733 have been re-assembled into 3 contigs [BQ426757; CU686461; CU686207] and one singleton [AM853364] in the most recent assembly of C. gigas transcriptome (GigasDatabase, version 8, February 2011).
