The Iroquois (Iro) family of genes are found in nematodes, insects and vertebrates. They
usually occur in one or two genomic clusters of three genes each and encode transcriptional …

▪ Abstract During the past decade, much progress has been made in understanding how the
adult fly is built. Some old concepts such as those of compartments and selector genes have …

The honeybee Apis mellifera has major ecological and economic importance. We analyze
patterns of genetic variation at 8.3 million SNPs, identified by sequencing 140 honeybee …

The Drosophila wing imaginal disc is a tissue of undifferentiated cells that are precursors of
the wing and most of the notum of the adult fly. The wing disc first forms during …

Protein ser/thr phosphatase 2A family members (PP2A, PP4, and PP6) are implicated in the
control of numerous biological processes, but our understanding of the in vivo function and …

The origin of insect wings has long been debated. Central to this debate is whether wings
are a novel structure on the body wall resulting from gene co-option, or evolved from an …

Genome-wide RNA interference (RNAi) screens have identified near-complete sets of genes
involved in cellular processes. However, this methodology has not yet been used to study …

The segmental heritage of all vertebrates is evident in the character of the vertebral column.
And yet, the extent to which direct translation of pattern from the somitic mesoderm and de …

Understanding how novel complex traits originate is a foundational challenge in
evolutionary biology. We investigated the origin of prothoracic horns in scarabaeine beetles …

The transcription factors GATA3 and Pax2 are expressed throughout development of the
mouse inner ear. We have used antibodies to study their temporal and spatial expression …
