[0033] Materials and Methods

[0034] Experimental animals and sample collection:

[0035] A total of 188 healthy adult Muchuan black-bone chickens were selected in this experiment, and the experimental subjects were all under the unified feeding and management conditions of Muchuan County Heifenghuang Silky Chicken Industry Co., Ltd. Blood collection: Use a disposable blood collection needle to collect blood through the wing vein into a vacuum blood collection tube containing sodium citrate anticoagulant, and mix well. At the same time, the skin color (black, light black, white) of silky chickens was recorded.

Abstract

The invention provides an application of a skin color-associated SNP marker in genotyping of black-bone chickens. The SNP marker is located at 2228 bp upstream of a transcription initiation site in apromoter region of a TYR gene, and a base with polymorphism is adenine A or thymine T. The SNP genotype detection primer has high specificity, single detection band and accurate typing results. In combination with a provided detection method, the whole operation process is simpler and more efficient, and the cost is lower. Rapid and accurate individual screening is achieved, and a basis for breeding development and protection of black-bone chicken varieties is provided.

Description

technical field [0001] The invention belongs to the field of molecular biology detection, and in particular relates to the application of a color-related SNP marker in silky chicken genotyping. Background technique [0002] Chicken skin color is a very important breed characteristic as a quality trait. Chicken skin color has an important economic use due to different market consumption needs. The skin color of poultry is mainly divided into three types: white, yellow and black, and the black skin is represented by silky chicken. [0003] Black-bone chicken has special nourishing and medicinal value, and its most notable feature is that it contains a large amount of melanin in the body. As an important active substance, black-bone chicken melanin has the functions of scavenging free radicals, anti-oxidation, delaying aging and improving body immunity. Studies have shown that black-bone chicken melanin can enrich trace elements such as Cu, Mn, Fe, Co and Ni, and the above e...
