“…These genes have been identified in a few species (Matsuda et al, 2002;Kamiya et al, 2012;Yano et al, 2012) and have been used as chromosomal markers to distinguish pairs of sex chromosomes (Okutsu et al, 2015). In addition, functional genomic studies (transcriptomics) currently applied to fish have identified genes that are complementary to those considered essential for sex determination (Zhang et al, 2011;Yano et al, 2012;Sun et al, 2013;Tao et al, 2013;Lu et al, 2014).…”

In the present study, we aimed to identify masculinized genotypic females of Rhamdia quelen on the basis of the sex ratio of the progeny. Masculinizing diets containing 3 levels of 17α-methyltestosterone (MT; 60, 90, or 120 mg kg -1 ) were administered to R. quelen fry. Thereafter, 5 phenotypic males from each MT treatment were crossed with normal females, and their progenies were sexed. At least 1 male from each treatment group generated progeny with a higher female:male ratio. These males, designated M60, M90, and M120, were crossed again with 3 other normal females to re-evaluate the sex ratio of the progeny. Moreover, a normal male was used as a control. Again, we found a higher female:male ratio in the progeny of M60, M90, and M120. The control male produced 2 sets of balanced progeny and 1 with a lower female:male ratio. Although these breeders did not generate all-female progeny (79.75 ± 7.20% of females), our findings indicate that M60, M90, and M120 can be considered masculinized genotypic females of R. quelen, suggesting the involvement of autosomal genes or polygenic interactions in sex determination.

“…有趣的是, 基于精原干细胞和卵原细胞的性别可塑性, 如将虹鳟的卵原细胞分别移植入雌雄供体中, 可分别产生虹鳟的卵子和精子 [91] , Okutsu等人 [92] 提出了一条性别控制育种, 生产YY超雄虹鳟的新思路. 雌性供体能产生来自受体SSC、含有Y染色体的卵子, 它们与正常含有Y染色体的精子授精, 可产生YY超雄个体.…”

“…中国几代鱼类遗传育种学家在鱼类性别异形和性别决定的遗传基础研究以及性别控制育种技术方面进行了孜孜不倦的探索, 取得了许多重大突破 [16,19,50,51,95] . 除了上述人工雌核生殖结合性反转, 或辅助以分子标记选择育种生产牙鲆、黄颡鱼和尼罗罗非鱼单性种苗 [50,51] 以及通过"借腹怀胎"生产YY超雄虹鳟外 [92] , 在罗非鱼中还可利用分别具有XX/XY或ZW/ZZ性别决定型的不同种之间进行杂交以达到生产全雄或高雄比例后代的目的. 譬如, 早在1960年, Hickling [96] 首次报道了利用种间杂交产生全雄罗非鱼.…”

Kök hücreler farklılaşmamış hücre sınıfından, kendilerini yenileyebilme özelliğine sahip, özelleşmiş hücrelere farklılaşabilen hücrelerdir. Balıklarda ilk kök hücre çalışmaları 1992 yılında zebra balığı ile başlamıştır. Bu derlemede balık kök hücrelerin sınıflandırılması, kaynakları, önemleri, karakteristik özellikleri ve uygulama alanlarına değinilmiştir.
