There is now compelling evidence that many arthropods pattern their segments using a
clock-and-wavefront mechanism, analogous to that operating during vertebrate …

The panarthropod head represents a complex body region that has evolved through the
integration and functional specialization of the anterior appendage-bearing segments …

Background The red flour beetle Tribolium castaneum has emerged as an important model
organism for the study of gene function in development and physiology, for ecological and …

Genetic screens are powerful tools to identify the genes required for a given biological
process. However, for technical reasons, comprehensive screens have been restricted to …

Entomopathogenic fungi and their insect hosts represent a model system for examining
invertebrate-pathogen coevolutionary selection processes. Here we report the …

Abstract The Asian citrus psyllid, Diaphorina citri is the principal vector of huanglongbing,
which transmits Candidatus Liberibacter asiaticus. Trehalase is a key enzyme involved in …

The anterior-most unit of the crown-group arthropod body plan includes three segments, the
pre-gnathal segments, that contain three neuromeres that together comprise the brain …

Gene expression has been employed for homologizing body regions across bilateria. The
molecular comparison of vertebrate and fly brains has led to a number of disputed homology …

Beetle horns are attractive models for studying the evolution of novel traits, as they display
diverse shapes, sizes, and numbers among closely related species within the family …

Background Most of the known genes required for developmental processes have been
identified by genetic screens in a few well-studied model organisms, which have been …
