| Abstract: | Partial homeobox gene fragments were amplified from Patiriella exigua genomic DNA by PCR using degenerate primers. The primers spanned a region of 82 nucleotides within the homeobox, encompassing amino acids 21–47 of the homeodomain. The deduced amino acid sequences of the seven Hox gene sequences plus one Xlox-type gene sequence from P. exigua are presented and compared with similar sequences from other organisms. This work is a preliminary step in the analysis of the evolution of development in the Patiriella species group and the roles of Hox gene expression therein. |
