UASt regulatory sequences drive expression of an inverted repeat.
Embryos expressing Pglym78KK107771 under the control of either Scer\GAL4Mef2.PR or Scer\GAL4kirre.PU show a significant reduction in the size of the segmental border muscle (SBM) and DA1 muscle, and also in the number of nuclei present in these muscles.
Expression of Pglym78KK107771 under the control of Scer\GAL4Mef2.PR has no effect on heart development in the embryo.
Expression of Pglym78KK107771 under the control of Scer\GAL4elav.PU has no effect on nervous system development in the embryo.
Expression of Pglym78KK107771 under the control of Scer\GAL469B has no effect on epidermal development in the embryo.
Embryos expressing Pglym78KK107771 under the control of Scer\GAL4kirre.PU have thinner than normal muscles and contain unfused myoblasts.
Embryos expressing Pglym78KK107771 under the control of Scer\GAL4kirre.PU show a significant reduction in the size of the segmental border muscle (SBM) and DA1 muscle, and also in the number of nuclei present in these muscles. The defect appears to be due to a premature fusion arrest at 11-11.5 hours after egg laying.
The number of actin foci in the fusion-competent myoblasts is significantly reduced compared to wild type in stage 13 and 14 embryos expressing Pglym78KK107771 under the control of Scer\GAL4kirre.PU.
