Abstract:

Intact Hordeum vulgare seedlings degraded [2-14C]gramine, [2-14C]indole-3-carboxaldehyde and [2-14C]indole-3-carboxylic acid to 14CO2. The plants also degraded [6-3H]gramine to labelled water. Moreover, [2-14C, 6-3H]gramine is degraded to 3H2O through tritium-labelled anthranilic acid. These results point to a breakdown of the aromatic system of gramine by successive steps involving indole-3-carboxylic acid, N-formylanthranilic acid and anthranilic acid which then follows its known degradation pathway. The last steps of the process proceed at a very fast rate. © 1992.
