Transcriptomic analysis shows exogenous GA3 promotes fruit size and ripening in strawberries, indicating auxin plays a key role.

The research aims to understand how exogenous GA3 influences strawberry fruit development through hormone signaling.
Applied 20 mg/L GA3 to strawberry plants (Fragaria × ananassa ‘Benihoppe’)
Conducted transcriptomic and metabolomic analyses
Assessed fruit enlargement and ripening time.
GA3 treatment significantly increased fruit weight and dimensions
Advanced ripening by 7 days
Identified auxin (IAA) levels and key differentially expressed genes associated with signaling pathways.

Gao et al. (2025) studied this question.
