Genome-wide CpG methylation in Hydra viridissima by ONT nanopore sequencing

ABSTRACT: Genome-wide 5-methylcytosine (5mC) profiling at CpG dinucleotides in Hydra viridissima using Oxford Nanopore long-read sequencing with Dorado base modification detection. Five ONT runs (one symbiotic, four aposymbiotic clone 2) were basecalled with Dorado sup,5mCG_5hmCG, aligned to Carnegie v1 genome assembly (JBWVZK000000000), and methylation quantified with modkit. Global CpG methylation is ~9-10%, bimodal (88% unmethylated, 7% fully methylated). Unique genomic regions show higher methylation (12%) than repetitive regions (7.5%).
