A 14-bp insertion in endothelin receptor B-like (EDNRB2) is associated with white plumage in Chinese geese.

ABSTRACT:

Background

Gang goose is a native species with gray plumage in Sichuan, China. As a result of overhunting, the number of gray Gang geese has decreased dramatically. To keep the species from extinction, conservation work for Gang geese was undertaken. In the process of pure breeding of gray Gang geese, approximately 2% of the offspring of each generation were white. This study aims to explain the genetic mechanism of this phenomenon and provide reliable molecular markers for goose-related plumage color breeding.

Results

We used the method of pooled whole genome sequencing and Fst (fixation statistics) to identify the differentiation degree of alleles between gray Gang geese and white Gang geese from their offspring. In this way, EDNRB2, a key gene that affects the migration o
