Chromosome-scale genome assembly of Zoysia japonica uncovers cold tolerance candidate genes.

ABSTRACT: Zoysiagrass stands out as a crucial native turfgrass due to its exceptional abiotic stress tolerance, extensive adaptability, and high ornamental value. In this study, we generated a high-quality chromosome-level genome assembly of Compadre (COM) zoysiagrass, leveraging PacBio SMRT sequencing and Hi-C scaffolding technologies. The resulting genome assembly (312.42 Mb) is anchored on 20 chromosomes, with a Scaffold N50 of 18.72 Mb. In total, 49,074 genes and 306,768 repeat sequences were annotated in the assembled genome. The first chromosome-scale genome of Zoysia japonica 'Compadre' provides a critical genetic resource for cold-tolerant turfgrass breeding through identifying stress-responsive candidate genes. Additionally, we have successfully established a cell nucleus extraction and lib
