Identification of an antennapedia-like homeobox gene in the ascidians Styela clava and S. plicata.
Homeobox genes from the urochordates Styela clava (AHox2) and S. plicata (AHox3) were cloned and analyzed. The two genes are homologous and Antennapedia-like. The homeobox regions have 87% identity at the nucleotide level and are identical at the amino-acid level. No introns are present in the homeobox region of AHox3, and AHox3 is represented at a low copy number per haploid genome. AHox2 and AHox3 represent the second type of homeobox gene found in this evolutionarily and developmentally important group of organisms.
