Some statements with respect to the regeneration in hydra.
A. The major head inducer of the hypostome organizer is a set of Wnt proteins acting through the canonical B-catenin pathway.
B. The major head inducer of the hypostome organizer is a set of Wnt proteins acting through the noncanonical B-catenin pathway.
C. These Wnt proteins are seen in the apical end of the early bud, defining the hypostome region as the bud elongates
D. If the Wnt signaling inhibitor GSK3 is itself inhibited throughout the body axis, ectopic tentacles form at all levels, and each piece of the trunk has the ability to stimulate the outgrowth of new buds.
E. transgenic hydra made to globally misexpress the downstream Wnt effector ectopic tentacles form at all levels, and each piece of the trunk has the ability to stimulate the outgrowth of new buds.
Which of the following statements are incorrect?
