Cloning and expression of medaka Dachshund

Fast skeletal muscle myosin heavy chain gene cluster of medaka Oryzias latipes enrolled in temperature adaptation.

To disclose mechanisms involved in temperature acclimation of fish muscle, we subjected eurythermal fish of medaka Oryzias latipes to cloning of myosin heavy chain genes (MYHs). We cloned cDNAs encoding fast skeletal muscle myosin heavy chain (MYH) isoforms from cDNA libraries of medaka acclimated to 10 and 30 degrees C and observed that different MYH cDNA clones are expressed in the two temper...

Cloning and developmental expression patterns of Dlx2, Lhx7 and Lhx9 in the medaka fish (Oryzias latipes)

We have isolated three homeodomain and LIM-homeodomain developmental transcription factors from the medaka fish (Oryzias latipes): OlDlx2, OlLhx7, and OlLhx9, and we have studied their expression patterns in the developing and adult brain. This analysis showed that OlDlx2 and OlLhx7 (together with OlNkx2.1b) delineate the subpallial divisions of the medaka telencephalon, and that OlLhx9 exhibit...

Wild-derived XY sex-reversal mutants in the Medaka, Oryzias latipes.

The medaka, Oryzias latipes, has an XX/XY sex-determination mechanism. A Y-linked DM domain gene, DMY, has been isolated by positional cloning as a sex-determining gene in this species. Previously, we found 23 XY sex-reversed females from 11 localities by examining the genotypic sex of wild-caught medaka. Genetic analyses revealed that all these females had Y-linked gene mutations. Here, we aim...

Cloning and gene expression of cytochrome P450 gene from Alcanivorax borkumensis Bacterium

Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...
