May function in the proximal abscission zone cells to prevent water loss after floral organ shedding (Probable). May be involved in the reestablishment of desiccation tolerance in germinated seeds (Probable). Highly expressed in the epidermal abscission zone cells from flowers and siliques. Expressed in roots, vasculature of cotyledons and leaves, stigmas, anther filaments and pollen grains. Belongs to the LEA type 4 family.
