Other claims from this paper (12)
- Observation Cranberry fairy ring was consistently associated with the genus Helicobasidium.
- Observation ITS and LSU sequences placed isolates from New Jersey and Massachusetts in a distinct lineage within H. longisporum, designated H. longisporum III.
- Intervention effect Pathogenicity was confirmed in greenhouse inoculations.
- Observation Infection cushions characteristic of violet root rot pathogens were consistently present on symptomatic cranberry vines.
- Observation Tuberculina isolates were recovered from aecial rust pustules of P. minutissima on Decodon verticillatus near cranberry plantings.
- Observation Tuberculina isolates were genetically identical to Thanatophytum isolates from cranberry.
- Mechanism The Tuberculina findings support a holomorphic life cycle of cranberry fairy ring involving a rust-parasitic stage.
- Observation Vegetative compatibility group and genotyping by sequencing revealed high diversity among cranberry fairy rings.
- Mechanism New ring formation in cranberry results largely from independent mating events during the mycoparasitic phase.
- Observation Clonal spread of cranberry fairy ring within beds is limited.
- Mechanism Cranberry fairy ring is caused by a Helicobasidium–Thanatophytum–Tuberculina complex with soilborne and airborne components.
- Recommendation Management could target the rust-parasitic stage and associated alternate hosts of cranberry fairy ring.
