【多选题】How does the ethylene signaling pathway work in plant cells?
A.
In the absence of ethylene, the receptor directly activates an associated protein kinase, which then indirectly promotes the destruction of the transcription regulator that switches on ethyleneresponsive genes. As a result, the genes remain turned off.
B.
In the presence of ethylene, the receptor and kinase are both inactive, and the transcription regulator remains intact and stimulates the transcription of the ethylene-responsive genes.
C.
The kinase that ethylene receptors interact with is a serine/threonine kinase that is closely related to the MAP kinase kinase kinase found in animal cells.
D.
The ethylene receptor is located in the endoplasmic reticulum; because ethylene is hydrophobic, it passes easily into the cell interior to reach its receptor.
