 # Genome sequencing
 For generating a *Ribes nigrum* genome assembly, the cultivar Rosenthals Langtraubige was used. DNA was extracted and filtered for long fragments above 40 kbp in order to perform Oxford Nanopore (ONT) sequencing and PacBio sequencing. 
 
-Briefly, DNA was extracted, short fragments filtered out, DNA purity confirmed, and the libraries were prepared using the standard ONT protocol for the SQK-LSK112 kit. After DNA fragment repair and 3'-adenylation sequencing adapters were ligated to the DNA fragments, before a last purification step with AMPure XP beads. ONT sequencing was performed in-house, PacBio sequencing was performed by Genohub (Brigham Young University, Provo, UT, USA).
