Other claims from this paper (5)
- Observation Ach1-1 controlled P. expansum in apple wounds.
- Intervention effect Adding fresh juice partly restored germination in the antagonist’s presence.
- Observation Without the antagonist, conidial germination recovered completely at both juice concentrations.
- Intervention effect Exogenous nutrients reduced Ach1-1 protection of apple wounds, most strongly for amino acids, then vitamins, then sugars.
- Mechanism The authors infer that Ach1-1 biocontrol relies chiefly on competition for apple fruit nutrients, especially amino acids.
