ARF and Aux/IAA genes in tomato and strawberry fruit development. ARF genes are classified as activators or repressors based on their Arabidopsis homologs.

Activator or repressor	Gene name	Biological function (or process)	Phenotype	References
Repressor	SlARF2	Regulator of fruit ripening	Delayed ripening phenotype	[63]
Repressor	SlARF3	Regulator of epidermal cell development	Decreased density of trichomes and pavement cells	[64]
Repressor	SlARF4	Regulator of chlorophyll and starch accumulation in fruit	Dark green and blotchy ripening fruit	[65]
Activator	SlARF5	Cell division and expansion during early fruit development	Parthenocarpic fruit	[66]
Activator	SlARF6	Photosynthesis, sugar accumulation, and fruit development	Delay of fruit ripening	[67]
Activator	SlARF7	Auxin and GA signaling response pathways in fruit development	Parthenocarpic fruit	[6]
Activator	SlARF8	Auxin and GA signaling response pathways in fruit development	Parthenocarpic fruit	[68]
Repressor	SlARF9	Auxin-responsive, cell division activity	Small fruit size	[69]
Repressor	SlARF10	Chlorophyll and sugar accumulation	Dark green fruit color	[70]
Repressor	SlIAA3	Auxin and ethylene signaling pathways	Reduced apical dominance, lower auxin sensitivity	[71]
Repressor	SlIAA9	Mediator of auxin signaling in fruit set and leaf morphogenesis	Parthenocarpic fruit	[55, 68]
-	SlIAA27	Ethylene and auxin signaling	Slightly increased plant size	[72]
