Genomic characterization and fermentation study of the endophyte Stemphylium sp. (Aa22), a producer of bioactive alkyl-resorcinols. [PDF]
The genome of the previously described endophytic fungus Stemphylium sp. (strain Aa22) has been sequenced to near completion. Phylogenomic analysis placed strain Aa22 in close proximity to Stemphylium lycopersici. Strain Aa22 had been previously reported
