Analysis of mRNA from tomato fruits from wild-type and
transgenic tomato plants genetically engineered to lack ethylene has revealed
that gene expression during ripening is regulated by at least two independent
pathways;
I) Ethylene-dependent pathway
II) Ethylene-independent pathway
Some given genes involved in these two pathways,
a) ACC oxidase
b) respiratory metabolism
c) ACC synthase
d) chlorophyllase
e) lycopene and aroma biosynthesis
Which of the following is the correct combination from the given pathways and its included genes?

Hook formation and maintenance result from ethylene-induced
asymmetric growth, indicating that
phytochrome is the photoreceptor involved in this process
a) Red light induces hook folding, and far-red light
reverses the effect of red
b) close interaction between phytochrome and ethylene
controls hook opening
c) Red light inhibits ethylene formation, promoting growth
on the inner side, thereby causing the hook to open
Which of the following combination from the given statements is correct?
