What will be the effect light in GA biosynthesis?
a) Light basically activates the GA 3β-hydroxylase which
adds a hydroxyl group (OH) to carbon 3 of GA20 and convert GA20 to GA1
b) light-induced increase in the transcription of the gene
for GA3ox, which converts GA20 to GA1
c) light-induced increase in the transcription of the gene
for GA2ox, which converts GA20 to
GA29
d) light-induced decreases the transcription of the gene for GA3ox, which converts GA20 to GA1
