Homeobox genes have been implicated in a number of regulatory processes associated with the embryonic patterning and cell differentiation of eukaryotes (McGinnis and Krumlauf, 1992). The homeobox is a 180 bp DNA sequence which encodes a 60 amino acid protein motif, the homeodomain, that has been shown to serve as the DNA binding site for a phyletically and functionally diverse class of transcri...

Homeobox transcription factors exert essential roles in embryogenesis and are thought to govern regenerative cell differentiation. In this issue of Cell, MacLean and colleagues (MacLean et al., 2005) describe a new homeobox gene cluster composed of genes selectively expressed in reproductive tissues. Remarkably, the cluster is on the X chromosome, and the genes display a colinear pattern of exp...
We have used subtractive hybridization to isolate cDNA clones whose expression were up-regulated in transgenic tobacco ectopically expressing the rice homeobox gene, OSH1. Thirty-nine distinct cDNA clones, which we term HRGs (Homeobox Regulated Genes), were identified. Some of them were specifically expressed in transformants, indicating that their expression was possibly regulated by transgene.
The Hex/Prh homeobox gene is expressed in a subset of adult blood cell types and may play a role in the differentiation of the myeloid and B-cell lineages. In a search for homeobox genes involved in cardiovascular development, we have independently isolated a Xenopus laevis cDNA which appears to be the amphibian orthologue of Hex/Prh. Based on high sequence similarity in a number of regions, pa...
Homeobox genes play crucial roles for the development of multicellular eukaryotes. We have generated a revised list of all homeobox genes for Caenorhabditis elegans and provide a nomenclature for the previously unnamed ones. We show that, out of 103 homeobox genes, 70 are co-orthologous to human homeobox genes. 14 are highly divergent, lacking an obvious ortholog even in other Caenorhabditis sp...
