Prohydrojasmon is a synthetically made plant growth regulator that is structurally similar and functionally identical to jasmonic acid, a naturally occurring plant growth regulator present in all vascular plants. Prohydrojasmon is involved with fruit color development in red apple varieties by enhancing the accumulation of anthocyanin, which is a red pigment and found predominantly in outer cell layers such as the epidermis and mesophyll cells in flowers and fruits.
