Other claims from this paper (9)
- Intervention effect Blossom Protect did not induce induced systemic resistance pathway genes.
- Association PR gene induction coincided with increased plant-derived salicylic acid.
- Intervention effect E. amylovora inoculation suppressed PR expression in untreated flowers.
- Intervention effect Blossom Protect pretreatment offset pathogen immune repression of PR expression.
- Intervention effect Blossom Protect pretreatment prevented infection after pathogen inoculation.
- Observation PR gene induction occurred two days after Blossom Protect treatment.
- Mechanism PR gene induction required direct flower–yeast contact.
- Observation Some treated flowers had deterioration of the hypanthium epidermis.
- Mechanism The authors suggest PR induction may arise from A. pullulans pathogenesis.
