Identification of key candidate genes and marker metabolites of melanin synthesis in black-bone chicken.

ABSTRACT:

Background

Blackness and growth traits are regarded as crucial economic traits in black-bone chicken production. In order to meet consumers' demand for black-bone chickens, it is necessary to study the mechanisms of body weight growth and melanin deposition in black-bone chickens. The genetic variations in growth traits, blackness traits, breast muscle transcriptome, and metabolism were compared between the Yanjin black-bone (YJ) chicken group (n = 20) and Jinling Partridge black-bone (JL) chicken group (n = 20). In addition, very high-melanin content (HB) individuals (n = 6) and very low-melanin content individuals (LB) (n = 6) were selected from the JL chicken group to investigate the melanin synthesis mechanism.

Results
