We identified the hunchback-like (hb) gene in the Capitella polychaete, revealing its role in early development. Its expression patterns suggest the anterior organizing function of hb in flies may have evolved in arthropods or insects.

Area of Science:

  • Developmental Biology
  • Evolutionary Biology
  • Genetics

Background:

  • The hunchback (hb) gene is crucial for anterior patterning in flies.
  • Understanding hb homologues in other animals provides insights into body plan evolution.

Purpose of the Study:

  • To characterize the segmentation gene homologue hunchback-like (Cc-hb) in the basal polychaete Capitella capitata.
  • To investigate the expression patterns and potential function of Cc-hb during annelid development.

Main Methods:

  • Utilized a pan-annelid cross-species antibody against the hunchback-like gene product.
  • Examined Cc-hb expression during cleavage, gastrulation, and organogenesis in Capitella capitata.

Main Results:

  • Cc-hb exhibits maternal and zygotic expression throughout early development.

  • Cc-hb is detected in the developing gut, epithelia, and neurons, but not in trunk segmental precursors.
  • Expression patterns show similarities to leech hb homologues, with differences potentially linked to life history variations.

    • Conclusions:

    • Cc-hb plays a role in early annelid development, distinct from its anterior patterning role in flies.
    • The anterior organizing function of hb likely originated in the arthropod or insect lineage, not in the common ancestor of annelids.
