Figure 1. The tissue distribution of AjNOS, Ajarginase and Ajagmatinase in normal sea cucumber detected by quantitative PCR.

The transcript levels in coelomocytes, intestine, tentacle, and respiratory tress were normalized to that in muscle. Five biological replicates were performed in the experiment and the obtained data were expressed as the mean ± SD (n = 5). Asterisks indicated significant differences: *P < 0.05, **P < 0.01.
