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 Oxformd 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).
