摘要

Sinodiscula camellicola is the causative agent of tea anthracnose, leading to severe leaf withering and defoliation. This disease compromises plant growth, reduces yield and quality, and causes substantial economic losses to the tea industry. However, research into the pathogenic mechanisms, host adaptation, and evolution of S. camellicola has been hampered by the scarcity of high-quality genome assemblies. By integrating Illumina short-read, PacBio HiFi, and Hi-C sequencing data, we generated a chromosome-level genome assembly for S. camellicola. The 41.79 Mb genome is organized into nine scaffolds and nine contigs (41.79 Mb, 100%), all anchored to nine chromosomes, with a scaffold N50 of 4.45 Mb. Using the fungi_odb10 dataset (n = 758), BUSCO analysis revealed a genome assembly completeness of 98.8%, including 98.7% single-copy genes and 0.1% duplicated genes. A total of 2,978,299 bp of repeat sequences and 9,918 protein-coding genes were predicted. The high-quality genome assembly of S. camellicola provides critical insights into its pathogenic mechanisms and supports the development of science-based strategies for effective disease management in agriculture.
