Expression of SpAIDLs in S. purpuratus. a The expression levels of SpAIDL1, 2, 3, 4a, 9, and 18S RNAs in coelomocytes (C), the esophagus (E), the small intestine (SI), the large intestine (LI), and the gonad (G) obtained from three individual S. purpuratus (Sp146♀, Sp147♂, and Sp148♀) were measured by RT-qPCR with two technical replicates per sample. The expression levels are normalized to the amounts of 18S, and the error bars indicate the standard deviation. The insets are a magnified view. b, c Six animals were injected with either live V. diazotrophicus (Sp138, 139, and 140) or sterile sea water (Sp141, 142, and 143). The time course of SpAIDL2, SpAIDL9, and SpIL17-9 expression levels were measured by RT-qPCR with each data point being the mean of two technical replicates. The expression levels were first normalized to 18S and then to the expression at t = 0 for each transcript for each sea urchin. The horizontal bars indicate the mean
