Aberrant gene expression at the creatine kinase loci during Barbus hybrid development (Cypriniformes, Teleostei).

The tissue specificity and ontogeny of creatine kinase (CK, EC 2.7.3.2) are reported for tiger, rosy, ruby, cherry and gold barbs, and in interspecific hybrids where the tiger barb is the maternal parent. The spatial expression of CK isoenzymes in Barbus is consistent with the tissue patterns reported in other teleosts. In general, as the taxonomic (genetic) distance between the parental species increases, a corresponding delay in embryonic gene expression occurs; suggestive of species-specific effector molecule/sensor gene induction thresholds.

Comparison of the spatial and temporal expression of supernatant malate dehydrogenase in Barbus hybrids (Cypriniformes, Teleostei).

The tissue specificity and ontogeny of supernatant malate dehydrogenase (s-MDH) are reported for the tiger barb, cherry barb, and their reciprocal hybrids. The tissue distribution of s-MDH isozymes in Barbus is consistent with the patterns reported in other teleosts. The expression of the Mdh-B locus is correlated with the initial muscle contractions of the developing embryos. It is suggested that the state of muscle cell differentiation may be the stimulus necessary for the expression of this locus in Barbus. Expression of maternal and paternal alleles at the B locus are synchronously delayed in reciprocal hybrids, as compared to their expression intraspecifically.
