zBbs1 and zNphp7.2 morphant embryos showed defects in convergent extension movements.
(A) Representative side views of control embryos and morphants demonstrate the analysis of the body gap angle which is inversely related to length of the body. Embryos were randomly picked at 8–10 somite stage. Open arrowhead marks first somite, filled arrowhead ninth somite respectively. Scale bar = 200 µm. (B) The expression of krx20/myod1 in morphant embryos showed shortened body axis with significantly broader somites compared to control. (C) The morphants of zbbs1 and znphp7.2 showed wider body gap angle compared to control embryos. The numbers in the brackets (n) are the numbers of total embryos which were examined.
