Figure 2

Expression of MlNR1 (A-J) and MlNR2 (K-N) in embryos and juveniles of Mnemiopsis. A-E show aboral views of MlNR1, with F-J showing lateral views of the corresponding embryo. (A-B, F-G) MlNR1 expression in ectoderm of the future tentacle bulb (tb) in the gastrula and late gastrula stage. (C-D, H-I) Expression continues in ectoderm of future tentacle bulb as well as in additional domain along the sagittal plane (arrowhead) in the postgastrula. (E, J) MlNR1 expression is restricted to the apical organ (ao) in the cydippid stage. (K-N) MlNR2 is broadly detected in the endoderm (en) in developmental stages after gastrulation and in the cydippid. It is only in the most aboral part of the pharynx (ph). There are also additional domains in the ectoderm (white arrowheads).
