we examine how the deregulation of growth-promoting and growth-inhibiting signaling pathways contributes to tumorigenesis. Mutations-
A. A mutation that alters a single amino acid (valine to glutamine) in the transmembrane region of the HER2 receptor
B. A deletion that causes loss of the extracellular ligand-binding domain in the EGF receptor Results-
i. dimerization of the receptor, even in the absence of the normal EGF-related ligand, transforming it into the oncoprotein, a constitutively active kinase
ii. to constitutive activation of the kinase activity of the resulting oncoprotein
iii. no dimerization, even in the presence of the normal EGF-related ligand, repression of kinase activity
which of the following results are displayed after these mutations?

Blue light stimulated opening of stomata, closing of stomata is also takes place by many other such mutants and mechanisms such as,
a.) npq1 mutants leads to closing of stomata
b.) In high PPFD leads to conversion of violaxanthin to zeaxanthin which will leads to closing of stomata
c.) Green light in the 500 to 600 nm region of the spectrum, abolishes the opening of stomata
d.) Mutant of phototropin 1 & 2 (PHOT1/PHOT2) leads to closing of stomata
e.) Starch content in the guard cell decreases during closing of stomata at the end of the day
Which of the following given statements will be correct for closing of stomata?
