Chromosomal-level genome assembly of Cronartium ribicola from Luquan County, Yunnan Province, China
Cronartium ribicola is a globally distributed fungal pathogen that infects five-needle pines, causing widespread tree mortality. In this study, we report a Chromosomal-level genome assembly of C. ribicola LQ (308.07 Mb, N50 = 3.56 Mb, GC content = 37.72%) using integrated Illumina short-read, PacBio long-read, and Hi-C sequencing technologies. Genome annotation identified 10,222 protein-coding genes, with 91.67% comprising repetitive sequences. Benchmarking Universal Single-Copy Ortholog (BUSCO) analysis demonstrated 95.01% genome completeness, supported by a high QV value of 59, with functional annotations covering 88.32% of the genes. A total of 352 carbohydrate-active enzyme (CAZyme) genes, predominantly glycoside hydrolases (45.17%), and 8 secondary metabolite biosynthetic gene clusters were identified, indicating strong host tissue degradation capability and diverse virulence factors. This study provides key genomic resources for understanding the pathogenic mechanisms, host interactions, and resistance gene discovery of C. ribicola, laying the foundation for the development of virulence-targeted control strategies.
