Gene expression in bryozoan larvae suggest a fundamental importance of pre-patterned blastemic cells in the bryozoan life-cycle
(BioMed Central, 2011-06-06)
Background: Bryozoa is a clade of aquatic protostomes. The bryozoan life cycle typically comprises a larval stage, which metamorphoses into a sessile adult that proliferates by asexual budding to form colonies. The homology ...
Coordinated spatial and temporal expression of Hox genes during embryogenesis in the acoel Convolutriloba longifissura
(BioMed Central, 2009-10-01)
Background: Hox genes are critical for patterning the bilaterian anterior-posterior axis. The evolution of their clustered genomic arrangement and ancestral function has been debated since their discovery. As acoels appear ...
Developmental diversity in free-living flatworms
(BioMed Central, 2012-03-19)
Abstract Flatworm embryology has attracted attention since the early beginnings of comparative evolutionary biology. Considered for a long time the most basal bilaterians, the Platyhelminthes (excluding Acoelomorpha) ...
