The pan-genome concept encompasses all individual genome sequences within a species, comprising both core and variable genes. In recent years, it has emerged as a promising avenue for advancing plant genetic evolution and cultivating desirable traits. This review provides a comprehensive overview of pan-genome representation, detailing both linear pan-genome and graph-based pan-genome. It further presents a thorough analysis of the assembly methods for these pan-genomic structures and discusses the widely used software tools and processes for their construction, including VG, Minigraph, and PGGB. The paper concurrently delineates the fundamental factors that influence pan-genome quality, which include genome assembly quality, accurate annotation, identification of homologous genes, and strategic sample selection. Furthermore, we investigate the pan-genome’s applications in plant genomics and provide a summary of recent research findings related to the plant pan-genomes, particularly in elucidating genetic transformations during domestication, uncovering genetic variations linked to agronomic traits, and offering insights to guide breeding endeavors.
