10x WGS Papaver bracteatum
HMW DNA samples were prepared as described in Vaillancourt et al. (2019)42. Long read sequencing was performed by the University of York Bioscience Technology Facility Genomics lab, using the Oxford Nanopore Technologies MinION and PromethION platforms. Sequencing libraries were prepared using ONT's ligation sequencing kit SQK-LSK106, using a minimum of 5 ?g high quality DNA.
