Abstract
MicroRNAs (miRNAs) form an abundant class of nonβcoding RNA genes that have an important function in postβtranscriptional gene regulation and in particular modulate the expression of developmentally important transcription factors including Hox genes. Two families of microRNAs are genomically located in intergenic regions in the Hox clusters of vertebrates. Here we describe their evolution in detail. We show that the micro RNAs closely follow the patterns of protein evolution in the Hox clusters, which is characterized by cluster duplications followed by differential gene loss. J. Exp. Zool.

## Abstract Compared with other diploid teleosts (2__n__=48), anguilloid fish have a specialized karyotype (2__n__=38) and remarkable morphological variation, and represent one basal group species of teleosts. To investigate the __Hox__ gene/cluster inventory in basal teleosts, a PCRβbased survey o
One of the most remarkable recent findings in developmental biology has been the colinear and homologous relationships shared between the Drusuphila HOM-C and vertebrate Hox homeobox gene complexes. These relationships pose the question of the functional significance of colincarity and its molecular
