Gibberellin biosynthesis precursor is____
#Question id: 11593
#I Life Science/ Life Sciences Group – I-V
Following are given stages of gibberellin biosynthetic
pathway;
a) Geranylgeranyl diphosphate (GGPP) is converted to
ent-kaurene via copalyl diphosphate
(CPP) in endoplasmic reticulum
b) In the endoplasmic reticulum, conversion of ent-kaurene
into GA12 or GA53 depending on whether the GA is hydroxylated at carbon 13
c) the conversion of GA12 or GA53 into other GAs in cytosol
proceeds with a series of oxidations at carbon 20
d) GA20 is then oxidized to the active gibberellin, GA1, by
a 3β-hydroxylation reaction
Which of the following is the correct statements of GA biosynthesis?
