Abstract

Alternaria alternata is a generally saprophytic fungus. Its genome consists of 10 autosomes, while some strains have one or two additional chromosomes, called a conditionally dispensable chromosome (CDC). A CDC is not required for reproduction but confers host-specific pathogenicity. We sequenced the genome of the peach pathotype of A. alternata using Nanopore and assembled it into 20 sequences. The 10 largest sequences corresponded to 10 gapless sequences of A. solani autosomes, and 1 sequence was a mitochondrial genome. Nine other sequences may be derived from CDCs because of lack of similarity with autosomes of other Alternaria spp. The sequence information could provide novel insights into genomes of Alternaria spp. and on the biosynthesis of a novel host-specific toxin in the peach pathotype of A. alternata.
