Effects of IAA application on the metabolism of [14C]GA1 in decapitated peas. Shown is the metabolism of [14C]GA1 to [14C]GA8 in decapitated peas (A) and decapitated peas treated with IAA (B; 3,000 μg g−1). [14C]GA1 was applied to leaf 8, and internode 8-9 tissue was harvested 10 h after application of the substrate. [14C]GAs were chromatographed as methyl esters. Identities of peaks are indicated. Data are shown as the percentage of total radioactivity in the HPLC run. The levels of radioactivity recovered were: controls, 19.5 ± 1.8 dpm × 10−3; IAA treated, 31.9 ± 3.8 dpm × 10−3; n = 2.
