In the lamella, expression is localized to the cell layers opposing the fruit tissue, and to the parenchyma surrounding the vascular tissue. In the fruit vesicles, expression is restricted to the peripheral cell layers and stalk cells. High levels of expression are detected in the core matrix.SIMILARITY:Belongs to the pectinesterase family."
