Info:
The authors present a high-quality de novo genome assembly of Cryphonectria parasitica, and invasive fungus that causes chestnut blight, using Oxford Nanopore and Illumina sequencing. The assembly was compared to a recently published reference genome. The comparison showed little difference in gene and transposable element repertoires but showed significant chromosomal rearrangements. The authors suggest that the differences likely have implications with regard to gene regulation and mating of invasive fungi.
BluePippin was used to High-Pass size select (>20KB) using the High Pass Plus cassettes prior to library preparation for the Oxford Nanopore GridION.
