Figure Caption

Fig. 9 Pdlim7 and Tbx5 directly regulate tbx2b AV expression. (A-C) In situ hybridization of tbx2b 48 hpf at the AV boundary in wild-type (A), hst/+ (B), and hst/hst (C) embryos. (D) AV boundary expansion of tbx2b in wild-type embryo after 2 ng MO2 injection. (E) tbx2b expression in hst/+ embryo injected with MO2 or (F) injected with 75 pg pdlim7 mRNA. (G) Quantification of tbx2b expression levels in uninjected controls (n = 94), 2 ng MO2 (n = 70), and 75 pg mRNA (n = 92). (H-J) Schematics illustrating the effect on the Tbx5 target gene tbx2b in wild-type (H), Pdlim7 MO (I), or pdlim7 mRNA (J) injected embryos.
