Some given statements about ethylene signalling pathways are
listed;
a) Ethylene receptors are interact with two downstream
signaling proteins, CTR1 (CONSTITUTIVE TRIPLE RESPONSE1) and EIN3
(ETHYLENE-INSENSITIVE3)
b) CTR1 is a soluble serine/threonine kinase that is
associated with ethylene receptors, while EIN2 is an ER transmembrane protein
with a cytosolic C-terminal domain that is a target for CTR1 kinase activity
c) EIN2 is required to stabilize transcription factors of
the EIN3 (ETHYLENEINSENSITIVE3) family, which activate the transcription of
ethylene-responsive genes
d) EIN3 is required to stabilize transcription factors of
the EIN2 (ETHYLENEINSENSITIVE2) family, which activate the transcription of
ethylene-responsive genes
Which of the following is the correct statements of auxin signalling pathway ?
