IAA has been found to be conjugated to both high- and
low-molecular-weight compounds such as,
a) Low-molecular-weight conjugated auxins include esters of
IAA with glucose or myo-inositol and amide conjugates such as IAA-N-aspartate
b) High-molecular-weight IAA conjugates include IAAglucan
and IAA-glycoproteins found in cereal seeds
c) High-molecular-weight conjugated auxins include esters of
IAA with glucose or myo-inositol and amide conjugates such as IAA-N-aspartate
d) Low-molecular-weight IAA conjugates include IAAglucan and
IAA-glycoproteins found in cereal seeds
Which of the following is the correct prediction about low-and high-molecular weight ?

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?
