ClTST2

Gene Details:

Molecular and biochemical analyses indicated that ClTST2 encodes a vacuolar membrane protein, whose expression is associated with tonoplast uptake and accumulation of sugars in watermelon fruit flesh cells.
Overexpression of ClTST2 Increases Sugar Accumulation in Watermelon Fruit.
That transcription of ClTST2 is positively correlated with sugar content in watermelon fruit flesh.
Demonstrates that C. lanatus Sugars Will Eventually Be Exported Transporter 3 (ClSWEET3) and Tonoplast Sugar Transporter (ClTST2) participate in plasma membrane sugar transport and sugar storage in fruit cell vacuoles, respectively.
Knocking out ClAGA2, ClSWEET3, and ClTST2 affected fruit sugar accumulation.
Genomic signatures indicate that the selection of ClAGA2, ClSWEET3, and ClTST2 for carbohydrate partitioning led to the derivation of modern sweet watermelon from non-sweet ancestors during domestication.
