Fig. 6. The first five Tc'eve stripes are formed normally in
Tc'Krjaws. Ventral views of stage-matched wild-type (A-D)
and Tc'Krjaws (E-H) embryos. The youngest wild-type (A,B)
and all Tc'Krjaws (E-H) embryos have been triply labelled
for Tc'eve (brown), Tc'en and Tc'gt mRNA (both
blue); in the older wild-type embryos (C,D), only Tc'eve (brown) and
Tc'en or Tc'wg (blue) are labelled. Tc'gt
expression was used to identify mutant embryos: the posterior giant
domain(s) present in wild-type germbands (A,B) are missing in
Tc'Krjaws (E,F); black arrowheads indicate the position of
these domains. In older Tc'Krjaws embryos, two ectopic
Tc'gt domains appear in the first and third thoracic segments (grey
arrowheads in F-H). In Tc'Krjaws mutant germbands (E,F),
the primary eve stripes 3 and 4, and the secondary segmental stripes
of eve2 form in a similar way to wild type (A,B) (stripes
eve1a and eve1b are partially obscured by en
stripes and the maxillary Tc'gt expression). Later on, eve3
splits into segmental stripes, while eve5 becomes detectable (C,G).
The segmental stripes 4a and 4b remain imperfect in
Tc'Krjaws, while eve5 forms a sharp anterior
boundary (H).
