Asymmetric gene expression is initiated randomly in ntl and tbx16 mutants. (A–C) At 10–12 SS spaw is normally expressed in a symmetric ‘perinodal’ domain flanking KV (arrow in panel A) and is just being initiated asymmetrically in left LPM (arrowhead in panel A). All views are dorsal; left (L) and right (R) sides are indicated in panel A. In both ntl and tbx16 mutant embryos, perinodal spaw expression was greatly reduced or absent (arrow in panels B, C) and LPM expression was left-sided, right-sided (arrowhead in panels B and C) or bilateral (see Table 1). (D–F) At 17–19 SS spaw remained left-sided in wild-type embryos (D) and randomized in tbx16 mutants (E), but was bilateral in all ntl mutants (F) (see Table 1). (G–I) The nodal antagonist charon is expressed around KV in wild-type embryos (arrow in panel G) and tbx16 mutants (arrow in panel H), but is reduced or absent in ntl mutant embryos (arrow in panel I). |
