Construction of MC1R and ASIP Eukaryotic Expression Vector and its Regulation of Plumage Color in Japanese Quail ().

The Japanese quail expresses polymorphism in plumage colors, including black, yellow, white, wild-type (maroon), and various intermediate colors through hybridization of quail with different plumage colors. The expression levels of MC1R and ASIP play important roles in the regulation of plumage colors in birds. In this study, the eukaryotic expression vector of pcDNA 3.

Association of Tyrosinase (TYR) and Tyrosinase-related Protein 1 (TYRP1) with Melanic Plumage Color in Korean Quails (Coturnix coturnix).

TYR (Tyrosinase) and TYRP1 (Tyrosinase-related protein 1) play crucial roles in determining the coat color of birds. In this paper, we aimed to characterize the relationship of TYR and TYRP1 genes with plumage colors in Korean quails. The SNPs were searched by cDNA sequencing and PCR-SSCP in three plumage color Korean quails (maroon, white and black plumage).

[Discovery and genetic analysis of blue-eyed mutant in the white rex rabbits].

Using cross, backcross, and full-sib mating experiments, allelism test was conducted to study the genetic mechanism of blue-eyed mutant of the white rex rabbits originated from the F1 generation from the cross American White rex rabbits(♂) × Chinchilla meat rabbits(♀). The study showed that the reason for the blue-eyed mutant of the white rex rabbits was a recessive mutation in Vienna locus. When the V locus was homozygous for the recessive v gene, it was recessive epistatic to other loci (including A, B, C, D, and E), which also controlled the coat color.

[Effects of granulosa cells treatments and follicular fluid on cleavage rate and blastocyst rate of bovine oocyte after in vitro fertilization and culture].

Experiments were conducted to study the effects of granulosa cell (GC), follicular fluid and their interaction on cleavage rate and blastocyst rate of Bovine oocytes following in vitro maturation (IVM), in vitro fertilization (IVF) and in vitro culture (IVC). A total of 2178 oocytes were used for studies on maturation, fertilization and embryo development. The cleavage rate was affected significantly (P < 0.

[The study and use on genetics of plumage color in quail].

The main plumage traits including wild-type, white, dark black, brown, dark-white inlays, brown-white inlays, yellow, red and purple have been reported,which are related to 26 loci. The majority of the loci are at the autosome and five loci at the Z chromosome. Four loci have multiple allelic series.
