Figure 7. Runt gene expression in lancelet larvae (B. floridae).

Figure 7

Anterior site is located to the left and the dorsal site towards the top. Whole mount in situ hybridization at stages of 16 h (A, B), 26 h (C, D) and 33 h (E, F). A), C) and E) Runt gene exon 1 variant. B), D) and F) Runt gene exon 2 variant. Note that the primary pigment spot, indicated by an arrow, lays in the nerve chord and does not represent a Runt expression domain. An: Anterior notochord, Nt: Neural tube, Nc: Notochord, Hg: Hindgut, Pp: Primary pigment spot, Ppi: Preoral pit.
