(15) A function for this distributed vasa is postulated based on the observation that embryos from Bicaudal-D mothers, in which abdominal determinants are incorrectly localized to the anterior pole, do not show any ectopic vasa localization, though abdomen development at the anterior end depends on the amount of vasa protein in the embryo.
(16) These provocative features are reminiscent of that of K10, bicoid and Bicaudal-D gene transcripts and lead us to hypothesize that the yemanuclein-alpha gene plays a key role in egg organization.
