    Loss of maternal and zygotic R in RCD3 germ-line clones disrupts ventral cuticle resulting in twi-positive mesoderm remaining on the surface after gastrulation. In some RCD3 mutants the germband becomes twisted during gastrulation. Coupling between actomyosin constriction and cell shape change is disrupted in RCD3 mutants. Balls of actin and myosin appear at the apical surface of mesodermal cells, and cell constriction halts prematurely, with myosin balls not contiguous with adherens junctions.

    Mutant clones in the eye show no defect at early pupal stages. But in the resulting adult eyes scars indicate that mutant tissue does not survive to the adult stage. Remnants of rhabdomere are present in the degenerated tissue. Mutants derived from germline clones show (non-paternally-rescuable) embryonic lethality. Affected embryos show normal axis specification, including for the terminal system. Gastrulation is affected, for 50% of embryos the ventral furrow never closes, although the mesodermal precursors display the usual apical construction and membrane blebbing. At the time of ventral furrow formation nuclei of invaginating cells are found at a variety of levels, instead of in the more usual basal location. Dorsal migration of internalised mesoderm is less extensive than in wild type. Dorsal structures such as the dorsal vessel do not form. Tracheal development seems relatively unaffected. Pole cell migration is severely impaired. Only a small number of cells reach the gonad. Head involution frequently fails and dorsal closure fails 5-10% of the time. These defects are decreased by paternally rescuing R+. The cytoskeleton in gastrulating embryos seems relatively normal.
