“…In jetblack, all the body parts like plumage, comb, internal organs, eyes, skin, beak, shank, and claw are entirely black, whereas pencil and golden have white and golden color patches on the plumage, respectively ( Haunshi and Prince, 2021 ). Several unique characteristics, such as earlier egg-laying maturity, high-protein content, better disease resistance, and adaptation to the local environment, are attributed to the Kadaknath chicken ( Rout et al, 1992 ; Haunshi et al, 2011 ; 2022 ; Thakur et al, 2015 ; Jena et al, 2018 ; Shanmathy et al, 2018 ; Sahu et al, 2019 ; Haunshi and Prince, 2021 ; Sehrawat et al, 2021 ; Sharma et al, 2022b ; Jadhao et al, 2022 ). Understanding the genetics behind these traits will help establish the uniqueness of Kadaknath and guide de-extinction efforts and breeding programs.…”

Black-bone chicken (BBC) meat is popular for its distinctive taste and texture. A complex chromosomal rearrangement at the fibromelanosis (Fm) locus on the 20th chromosome results in increased endothelin-3 (EDN3) gene expression and is responsible for melanin hyperpigmentation in BBC. We use public long-read sequencing data of the Silkie breed to resolve high-confidence haplotypes at the Fm locus spanning both Dup1 and Dup2 regions and establish that the Fm_2 scenario is correct of the three possible scenarios of the complex chromosomal rearrangement. The relationship between Chinese and Korean BBC breeds with Kadaknath native to India is underexplored. Our data from whole-genome re-sequencing establish that all BBC breeds, including Kadaknath, share the complex chromosomal rearrangement junctions at the fibromelanosis (Fm) locus. We also identify two Fm locus proximal regions (∼70 Kb and ∼300 Kb) with signatures of selection unique to Kadaknath. These regions harbor several genes with protein-coding changes, with the bactericidal/permeability-increasing-protein-like gene having two Kadaknath-specific changes within protein domains. Our results indicate that protein-coding changes in the bactericidal/permeability-increasing-protein-like gene hitchhiked with the Fm locus in Kadaknath due to close physical linkage. Identifying this Fm locus proximal selective sweep sheds light on the genetic distinctiveness of Kadaknath compared to other BBC.

Black-bone-chicken (BBC) breeds are famous for their distinctive meat texture and taste. However, the relationship between BBC breeds, especially the Kadaknath breed native to India, is poorly understood. Here, we establish that all BBC breeds, including Kadaknath, share a common complex chromosomal rearrangement at the FM locus on the 20th chromosome, which is responsible for the melanin hyperpigmentation throughout the body. While we find breed-specific gene flow between BBC and commercial breeds, the shared ancestry of all BBC breeds and pattern of isolation by distance suggest Kadaknath is closely related to Tibetan BBC. Interestingly, two FM locus proximal regions (~70Kb and ~300 Kb) have signatures of selection unique to Kadaknath. These regions harbor several genes with protein-coding changes, with the Bactericidal/permeability-increasing-protein-like (BPIL) gene having two Kadaknath-specific changes within the protein domains. The absence of these changes in other BBC breeds suggests this variation arose after the separation of these breeds. Our results indicate that the rearrangement at the FM locus and protein-coding changes in the BPIL gene were selected simultaneously in Kadaknath due to close physical linkage. The identification of this FM locus proximal selective sweep sheds light on the distinctiveness of Kadaknath compared to other BBC.
