Outline of Final Research Achievements |
Identification of genes that express by stage specific manner and quantification of their mRNA levels in gonads were conducted throughout the periods of molecular sex differentiation, morphological sex differentiation, oocyte growth and maturation in Russian and Amur sturgeons using a next-generation sequencer. The information obtained from this study was utilized in the application for the development of techniques on sexing in the early developmental stage, induction of sexual maturation in the earlier gonadal developmental stage, production of good quality eggs and production of all female population.
