Genetic variations associated with adaptation in Acrocomia palms: A comparative study across the Neotropics for crop improvement.

ABSTRACT: Population genetic research has evolved, focusing on selection processes using single nucleotide polymorphisms (SNP) genotyping techniques to study crop traits and domestication. This study explores the adaptation process of three neotropical palms of Acrocomia, a genus that has high potential for oil extraction. Our research focused on their genetic structure, evolutionary significance, and implications of the selection signatures for breeding efforts. We employed genotyping-by-sequencing (GBS) focusing on outlier SNP markers to identify adaptive genes in A. aculeata, A. totai, and A. intumescens across their entire distributions. Our results reveal two major gene pools in A. aculeata: a Central American group and a South American group, mainly influenced by dispersal and biogeographic ba
