摘要： In this study, we report a high-quality chromosome-level genome assembly of Actinidia chinensis var. chinensis 'Guimi No. 2'. This cultivar, discovered in Guizhou karst ecosystems, exhibits resistance to Pseudomonas syringae pv. actinidiae (Psa). Using a combination of MGI short-read sequencing, PacBio HiFi long-read sequencing, and Hi-C technology, we generated a genome assembly of 608.43 Mb with a contig N50 of 20.70 Mb, and 99.70% of the assembly was successfully anchored onto 29 pseudochromosomes. The quality value (QV) and the LTR Assembly Index (LAI) of the assembled genome were 72.23 and 10.10. The BUSCO analysis indicated that the genome assembly and gene model prediction were 98.40% and 96.56% complete, respectively. A total of 251.15 Mb of repetitive sequences and 45,986 protein-coding genes were annotated. This genome assembly provides critical insights into A. chinensis's genomic architecture and serves as a foundational resource for elucidating disease resistance mechanisms against Psa, while enabling comparative phylogenomic studies across the Actinidia genus.
