Plant Pan-Genomics: Opportunities, Advances, and Challenges

Abstract

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 delves into the methodologies for constructing the pan-genome, encompassing various assembly techniques and strategies for representing this data in graphical or linear formats. Emphasis is placed on the critical aspects of high-quality genome assembly, precise annotation, homologous gene identification, and judicious sample selection in pan-genome analysis. Furthermore, we investigate the pan genome's applications in plant genomics, particularly in elucidating genetic transformations during domestication, uncovering genetic variations linked to agronomic traits, and offering insights to guide breeding endeavors.
