N2  - Incorporation studies with 14 CO2 suggested that 11-day-old barley seedlings biosynthesized an A1- like gibberellin de novo and that the biosynthesized gibberellin completely turned over within 12 h. Exogenous [14C]mevalonic acid, supplied in a variety of ways, was not incorporated into the gibberellins of barley seedlings. Barley seedlings, which failed to elongate in response to exogenous ent-kaurenoic acid, metabolized exogenous [17-14C]ent-kaurenoic acid to a few compounds, but not to a biologically active gibberellin. Dwarf rice seedlings (cv. Tan-ginbozu), which elongated in response to exogenous ent-kaurenoic acid, metabolized exogenous [17-14C]ent-kaurenoic acid to a number of radioactive compounds, one of which behaved like [14C]gibberellin A1 in that it showed radioactivity and biological activity at the expected retention time during gas-liquid chromatography.
