Abstract:
The metabolism of gibberelline (GAs) in intact plants of Raphanus sativus was investigated. With [(2)H]GA feeds, [(2)H]GA1 from [(2)H]GA4, and [(2)H]GA4 and [(2)H]GA20 from [(2)H]GA9 were metabolized. Since [(2)H]GA20 was not converted into [(2)H]GA1, endogenous GA1 may have been biosynthesized from GA9 via GA4 rather than from GA20. The radioactivity of [(3)H]GA9 and [(3)H]GA20 was much more strongly transported among the plant organs than that of [(3)H]GA1 and [(3)H]GA4.

Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
