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

Major histocompatibility complex (MHC) molecules are key players in initiating immune
responses towards invading pathogens. Both MHC class I and class II genes are present in …

Vertebrate segmentation relies on a mechanism characterized by oscillating gene
expression. Whether this mechanism is used by other segmented animals has been …

Extensive research into Drosophila melanogaster embryogenesis has improved our
understanding of insect developmental mechanisms. However, Drosophila development is …

Most of our knowledge of insect genomes comes from Holometabolous species, which
undergo complete metamorphosis and have genomes typically under 2 Gb with little signs of …

Modular body organization is found widely across multicellular organisms, and some of
them form repetitive modular structures via the process of segmentation. It's vastly interesting …

The hallmark of the arthropods is their segmented body, although origin of segmentation,
however, is unresolved. In order to shed light on the origin of segmentation we investigated …

Spiders belong to the chelicerates, which is an arthropod group that branches basally from
myriapods, crustaceans and insects. Spiders are thus useful models with which to …

Background Primordial germ cell (PGC) specification is a universal process across animals,
but the molecular mechanisms specifying PGCs are remarkably diverse. In Drosophila …

Sequential addition of segments in the posteriorly growing end of the embryo is a
developmental mechanism common to many bilaterians. However, posterior growth and …
