      Additional Comments

      Statement
      Reference

      The very low number of eggs laid by vasPH165 homozygous females is not rescued by maternal combination with bel::vasvas.C.bel.T:Avic\GFP-EGFP and the few embryos produced by the vasPH165;bel::vasvas.C.bel.T:Avic\GFP-EGFP females display severe defects in dorsal-ventral patterning.

      The failure to form pole cells as well as the impaired dorsal patterning (assessed by no. of ftz stripes) observed in embryos from vas1 homozygous mothers is partially rescued in progeny from vas1;bel::vasvas.C.bel.T:Avic\GFP-EGFP females.
