This compound binds to a receptor in the endoplasmic reticulum called ETR1, which then allows EIN2 to be cleaved and move into the nucleus. In the biosynthesis of this compound, Met Adenosyltransferase converts methionine to SAM, which is then converted to ACC. The biosynthesis of this compound is referred to as the Yang cycle.

This compound binds to a receptor in the endoplasmic reticulum called ETR1, which then allows EIN2 to be cleaved and move into the nucleus. In the biosynthesis of this compound, Met Adenosyltransferase converts methionine to SAM, which is then converted to ACC. The biosynthesis of this compound is referred to as the Yang cycle. The activity of the enzyme regulating ACC conversion increases with high levels of (*) IAA and cytokinins. One notable response to this compound is the thickening of the hypocotyl in seedlings, known as the triple response. This hormone is the reason that one bad apple can spoil the whole bunch. For 10 points, name this gaseous hormone in plants that regulates leaf abscission and fruit ripening.
