Multi-omics reveals gut microbiota-mediated environmental adaptation in Mallards and domesticated Shaoxing ducks.

ABSTRACT: Gut microbiota remodeling is a critical component of the domestication syndrome. However, the structural and functional consequences of domestication on gut microbiomes in ducks remain poorly understood. Understanding how domestication and associated ecological transitions influence gut microbial communities can shed light on host adaptation mechanisms. We performed integrated metagenomic and metabolomic analyses of the ileal and cecal microbiota from Mallards and Shaoxing ducks-two ecotypes of Anas platyrhynchos representing wild and domesticated lineages-to investigate microbial community structure, functional capacity, and host-microbe metabolic interactions. Principal coordinates analysis (PCoA) revealed distinct microbial stratification between intestinal compartments (ileum vs. cecum
