Description

nos 5' UTR and coding region, followed by the sensitised 3' UTR containing nucleotides 6-96 (the +1 localisation element sequence), 181-408 (the +3 localisation element sequence), and 548-786 of the nos 3' UTR. Tag:MS2 stem loops have been inserted near the terminus of the 3' UTR.

nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos carrying a Df(2L)BSC32/+ mutation display a reduction in abdominal segmentation, forming an average of 2.4 abdominal segments.

nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos carrying a aubQC42/+ mutation display a reduction in abdominal segmentation, forming an average of 2-3 abdominal segments. Mutant embryos display the normal number of pole cells.

nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos carrying a aubHN/+ mutation display a reduction in abdominal segmentation, forming an average of 3-4 abdominal segments.

nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos carrying a squHE47/+ mutation do not display a reduction in abdominal segmentation compared to nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos.

rump1 mutant embryos carrying a nosBN, nos+1+3.T:MS2\MCP.BS/nosBN mutation display an increase in the number of embryos that develop less than 8 abdominal segments.

rump1 mutant embryos carrying an aubQC42/+ mutation, and the mutation nosBN, nos+1+3.T:MS2\MCP.BS/nosBN , display an increase in the number of embryos that develop less than 8 abdominal segments.
