Umezawa et al showed that the signaling of this molecule is regulated by protein phosphatase 2C.
Umezawa et al showed that the signaling of this molecule is regulated by protein phosphatase 2C. The pathway for the synthesis of this compound begins with a zeaxanthin precursor and ends with the cleavage of a C40 carotenoid into xanthoxin, which is finally oxidized to this molecule; that process of this molecule's synthesis is called the MEP pathway. Functions of this hormone include promoting gene transcription for proteinase inhibitors in response to wounding and producing a-amylase in order to act against the effects of gibberellins. It also plays a major function in regulating the closure of the stomata. For 10 points, name this plant hormone that is sometimes called dormin, which is responsible for the inhibition of seed germination, fruit ripening and budding.
