Genome-wide mapping of 5-hydroxymethyluracil in the eukaryote parasite Leishmania

Background 5-Hydroxymethyluracil (5hmU) is a thymine base modification found in the genomes of a diverse range of organisms. To explore the functional importance of 5hmU, we develop a method for the genome-wide mapping of 5hmU-modified loci based on a chemical tagging strategy for the hydroxymethyl group.
