Gene: Sopen08g020450

General Information

Description Encodes a cysteine-rich peptide, a secretory factor that is produced in the mesophyll cells and acts on the epidermis to increase stomatal formation. Its mature form is a 45-aa peptide with three intramolecular disulfide bonds. It is proposed that STOMAGEN increases stomatal number by competing with two negative regulators of stomatal density, EPF1 and EPF2, possibly through direct interaction with the receptor-like protein TMM. | STOMAGEN (STOMAGEN) | FUNCTIONS IN: molecular_function unknown | INVOLVED IN: stomatal complex patterning, regulation of stomatal complex development, positive regulation of stomatal complex development, cell-cell signaling | LOCATED IN: endomembrane system | EXPRESSED IN: 19 plant structures | EXPRESSED DURING: 12 growth stages
