High-quality genome resource of Clonostachys rosea strain CanS41 by Oxford Nanopore long-read sequencing

Clonostachys rosea is a necrotrophic mycoparasitic fungus with excellent biological control ability against numerous fungal plant pathogens. Here, we performed genomic sequencing of C. rosea strain CanS41 using Oxford Nanopore sequencing technology. We generated a high-quality genome assembly (>99.99% accuracy), which comprised 26 contigs containing 60.68 Mb sequences with a GC content of 48.55% and a repeat content of 8.38%. The N50 contig length is 3.02 Mb.

In total, 20,818 protein-coding genes were identified and functionally annotated. Genes encoding secreted proteins and carbohydrate-active enzymes as well as secondary metabolic gene clusters were also identified and analyzed. In summary, the high-quality genome assembly and gene annotation provided here will allow further exploration of biological functions and enhance biological control ability of C. rosea.
