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
