Identification and Expression of cGnRH-II Gene in Three Strains Osphronemus gouramy (Soang, Jepun and Bluesafir)

Gouramy (Osphronemus gouramy) has very high economic value and is easy to cultivate. Currently there are about six strains that have been successfully cultivated based on their reproductive ability produce eggs, namely goose (soang, gouramy), jepun (japan, japonica), blue sapphire, paris, bastar (broiler) porcelain. One of the reasons for these differences in internal factors which can be seen through identification expression cGnRH gene each gouramy have. The functions signaling pituitary gland secrete hormone GtH. This study aims identify sequences values ​​resulting from three gouramyat different age levels. research method used was exploration jepun, sapphire) at levels (4 months, 8 12 months), were taken level. conducted several stages, organ preparation, isolation, sequence measurement expression. Sequence data analyzed using phylogenetic trees Way ANOVA test. results showed soang strain had a more similar than sapphire strain, resulting with did not give results.
