A High-Quality Genome Resource of Botrytis fragariae, a New and Rapidly Spreading Fungal Pathogen Causing Strawberry Gray Mold in the United States

Phytopathology. 2021 Mar;111(3):496-499. doi: 10.1094/PHYTO-05-20-0204-IA. Epub 2020 Oct 15.


Although Botrytis fragariae was only recently identified as a new Botrytis species that causes strawberry gray mold, its prevalence extends to many states of the eastern United States. Compared with B. cinerea, which is known to be the causal agent of gray mold on many crop plants including strawberry, B. fragariae appears to have specifically adapted to strawberry and exhibits distinct fungicide sensitivity. This is the first presentation of a high-quality genome assembly of B. fragariae with gene annotation based on sequence homology and deep transcriptome data. The genome sequence information from B. fragariae is expected to help reveal genomic features underlying its host specialization and evolution of distinct fungicide resistance and other novel pathogenicity mechanisms.

Keywords: disease control and pest management; fungal pathogens; genomics; techniques.
