Abstract: The high-quality reference genome serves as the foundation for genomics research. Currently, the majority of reference genomes remain incomplete. With the continuous development of long-read sequencing technology, an increasing number of species have been successfully assembled telomere-to-telomere（T2T） genomes. The T2T genome lays the foundation for in-depth study of complex regions such as centromeres, and is of great significance for the excavation of functional genes and the study of important biological mechanisms. This paper provides an overview of the research progress on plant T2T genomes, presents the corresponding assembly strategies with examples, discusses the significance and challenges of T2T genomes, and offers a prospective view of future developments.
