SlSTP9, a plasma-membrane sugar transporter in tomato anther endothecium/middle layers, is required for proper cell expansion, preventing shortened anthers and pollination failure.
- Why it matters: Sugar transporters are linked to floral development, but how they regulate anther architecture and pollination success through transcriptional control is unclear.
- What they did: Using CRISPR/Cas9 editing, yeast complementation, microscale thermophoresis, transcriptomics, and metabolic profiling, the study tested SlSTP9 function and found SlDof12 directly represses SlSTP9.
- The result: SlSTP9 loss causes excessive galactose accumulation, phenylpropanoid activation, and premature lignification, while SlDof12 overexpression reproduces the slstp9 floral defects and SlSTP9 overexpression increases fruit set.
