TY - JOUR AU - Hejnol, Andreas AU - Martindale, Mark Q. PY - 2009 DA - 2009/10/01 TI - Coordinated spatial and temporal expression of Hox genes during embryogenesis in the acoel Convolutriloba longifissura JO - BMC Biology SP - 65 VL - 7 IS - 1 AB - 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 to represent the sister group to the remaining Bilateria (Nephrozoa), investigating Hox gene expression will provide an insight into the ancestral features of the Hox genes in metazoan evolution.
