A point mutation in the intron of the C2H2 zinc-finger transcription factor FveJAG in Fragaria vesca causes complete suppression of two lateral leaflets in the sl2 mutant.
- Why it matters: Leaflet initiation in strawberry compound leaves is poorly understood, and identifying direct regulators is needed to map how leaf complexity is genetically controlled.
- What they did: The sl2 mutant was characterized genetically and by expression analyses, revealing that SIMPLE LEAF1 (SL1) directly targets the FveJAG promoter to activate transcription, with evidence that FveJAG functions downstream of FveMYB117a.
- The result: SL1 and FveJAG act in the same regulatory pathway, and their interaction with FveMYB117a supports a mechanistic network for compound leaf morphogenesis in Fragaria vesca.
