      form31 embryos show a discontinuous lumen in the dorsal trunk of the tracheal system.

      Amnioserosa cells of form31 mutant embryos are bigger and present a more regular, more round shape, and a exhibit a decrease in the amplitude of the cell contraction..

      form31 embryos exhibit delayed dorsal closure, with puckering of the dorsal epidermis, an unstretched leading edge, a malformed canthus and disintegration of the Amnioserosa.
