Circular DNA plasmid in the phytopathogenic fungus Alternaria alternata: its temperature-dependent curing and association with pathogenicity.

Genetics - 1 May 1997

Abstract excerpt

We found the presence of plasmid DNA in strain T88-56 of the Japanese pear pathotype of Alternaria alternata, which causes black spot of certain cultivars of Japanese pear by producing host-specific AK-toxin. The plasmid, designated pAAT56, was identified to be an approximately 5.4-kilobase (kb) circular molecule by electron microscopic observation and restriction endonuclease mapping. Southern blot analysis...
