The fate map of the arabidopsis embryo at the heart stage indicates that:

#Unit 5. Developmental Biology

  1. The primordia of the leaves, stems, and roots have already formed

  2. The three germ layers that will give rise to roots, stems, and leaves have formed

  3. A fate map the regions that will give rise to laves, stems, and roots can be drawn, although the cells are still undifferentiated, as is the case with the animal blastula

  4. Although none of the adult structures have formed, the regions that will give rise to the meristems, which will in turn give rise to adult structures, can be identified

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
