Near-Complete Genome Assembly of Alternaria brassicae-A Necrotrophic Pathogen of Brassica Crops.

Alternaria brassicae, a necrotrophic fungal pathogen, causes Alternaria blight, an important disease of brassica crops. Although many Alternaria spp. have been sequenced, no genome information is available for A. brassicae, a monotypic lineage within the Alternaria genus. A highly contiguous genome assembly of A. brassicae has been generated using Nanopore MinION sequencing with an N50 of 2.98 Mb, yielding nine full chromosome-level sequences. This study adds to the current genomic resources available for the genus Alternaria and will provide opportunities for further analyses to unravel the mechanisms underlying pathogenicity of this important necrotrophic pathogen.
