Journal ArticleDOI
Localized maternal orthodenticle patterns anterior and posterior in the long germ wasp Nasonia.
TL;DR: It is shown that Nasonia otd maternal mRNA is localized at both poles of the embryo, and resulting protein gradients pattern both poles, which means that localized NasonIA otd has two major roles that allow long germ development.
Journal ArticleDOI
A caudal mRNA gradient controls posterior development in the wasp Nasonia.
Eugenia C. Olesnicky,Ava E. Brent,Lori Tonnes,Megan Walker,Mary Anne Pultz,David S. Leaf,Claude Desplan +6 more
TL;DR: The study of anteroposterior patterning in insects that lack Bicoid can provide insight into the evolution of the diversity of body plan patterning networks and suggest that caudal is an ancestral master organizer of patterning, and that its role has been reduced in higher dipterans such as Drosophila.
Journal ArticleDOI
Members of the SNARE hypothesis are associated with cortical granule exocytosis in the sea urchin egg
TL;DR: The results suggest that at least some steps in the biology of cortical granules may be mediated by SNARE homologues, and this finding should facilitate examination of specific events of the fertilization reaction and the mechanism of stimulus‐dependent exocytosis.
Journal ArticleDOI
A major role for zygotic hunchback in patterning the Nasonia embryo
Mary Anne Pultz,Lori Westendorf,Samuel D. Gale,Kyle Hawkins,Jeremy A. Lynch,Jason N. Pitt,Nick L. Reeves,Jennifer C. Y. Yao,Stephen Small,Claude Desplan,David S. Leaf +10 more
TL;DR: A lesion in Nasonia hunchback is found to be responsible for the severe zygotic headless mutant phenotype, in which most head structures and the thorax are deleted, as are the three most posterior abdominal segments, which defines a major role forZygotic Nasonian hunchbacks in anterior patterning, more extensive than the functions described for hunch back in Drosophila or Tribolium.
Journal ArticleDOI
The jewel wasp Nasonia: querying the genome with haplo-diploid genetics.
Mary Anne Pultz,David S. Leaf +1 more
TL;DR: The jewel wasp Nasonia vitripennis is considered the “Drosophila melanogaster of the Hymenoptera” and offers insect geneticists a means for applying haplo‐diploid genetics to the analysis of developmental processes.
