Meeting Abstract 23-4 Friday, Jan. 4 11:00 – 11:15 Investigating the Molecular Basis of PGC Specification and Migration in a Hemipteran Insect LOCHAB, AK*; EXTAVOUR, CG; Harvard University alochab@g.harvard.edu For mature gametes to form, the first precursors of the sex cell lineage must be specified and correctly localized during embryonic development. These precursors are known as Primordial […]

Hox Genes Limit Germ Cell Formation in the Short Germ Insect Gryllus bimaculatus
Meeting Abstract 23-6 Friday, Jan. 4 11:30 – 11:45 Hox Genes Limit Germ Cell Formation in the Short Germ Insect Gryllus bimaculatus. BARNETT, AA*; NAKAMURA, T; EXTAVOUR, CE; DeSales University; Harvard University; Harvard University austen.barnett@desales.edu Hox genes are conserved transcription factor-encoding genes that specify the body regions of bilaterally symmetrical animals. In the cricket Gryllus bimaculatus, a […]
GENETICS OF STRUCTURAL COLORATION IN PIERID BUTTERFLY WINGS
Meeting Abstract 23-7 Friday, Jan. 4 11:45 – 12:00 GENETICS OF STRUCTURAL COLORATION IN PIERID BUTTERFLY WINGS RODRIGUEZ, LF*; COLE, J; FENNER, J; COUNTERMAN, B; Mississippi State University; Mississippi State University; Mississippi State University; Mississippi State University lfr36@msstate.edu Butterfly wing color patterns result from an arrangement of monochromatic scales containing both chemical pigments and a delicate architecture […]
Evolution of Anterior-Posterior Axis Specification and Patterning Insights from the Sea Urchin Embryo
Meeting Abstract 23-3 Friday, Jan. 4 10:45 – 11:00 Evolution of Anterior-Posterior Axis Specification and Patterning: Insights from the Sea Urchin Embryo RANGE , RC; Auburn University range@auburn.edu The early specification and patterning of cell fates along the primary body axis of many metazoan embryos relies on a gradient of Wnt signaling. In most embryos this patterning […]
Double your fun gene duplication and the diversification of novel cell types
Meeting Abstract 23-2 Friday, Jan. 4 10:30 – 10:45 Double your fun: gene duplication and the diversification of novel cell types BABONIS, LS*; MARTINDALE, MQ; Univ of Florida, Whitney Lab; Univ of Florida, Whitney Lab babonis@whitney.ufl.edu The question of how novelty arises has lurked in the background of evolutionary biology for decades. One common hypothesis suggests that […]
