During an ethylene signalling pathway, what will have done inside cytosol and nucleus . Given below some
prediction about presence and absence of ethylene in column B match with column
A
COLUMN A |
COLUMN B |
I- In the presence of ethylene |
a) ETR1 signaling is repressed and CTR1 is
inactive |
II-
In the absence of ethylene |
b) ETR1 activate CTR1, a Ser/Thr kinase |
|
c) CTR1 phosphorylates the C-terminal domain
of EIN2 |
|
d) The nonphosphorylated C terminus of EIN2 is
cleaved by a protease |
|
e) Phosphorylation of EIN2 inhibits
proteolytic cleavage |
|
f) EIN3 transcription factors are
ubiquitinated and degraded in the nucleus by the 26S proteasome |
|
g) EIN3 initiates a transcriptional cascade by
activating expression of ethylene-responsive genes, including ERF1
transcription factor, leading to ethylene responses |
