Allantoin metabolism in soybean plants as influenced by grafts, a delayed inoculation with Rhizobium, and a late supply of nitrogen-compounds

Reciprocal grafts between A62-1 (nodulating variety) and A62-2 (non-nodulating variety) of soybeans, delayed inoculation with Rhizobium and a late supply of N-compounds to nodulated and denodulated A62-1 plants were tested to study the regulation of allantoin production in soybeans.

In the upper portions of stems of the A62-2 plants grafted onto A62-1 plants, allantoin was accumulated in a significant quantity, but lower than the ungrafted intact A62-1 plants. The concentrations of odier nitrogenous and sugar components were similar to those of the ungrafted A62-1 plants. On the other hand, in the upper stems of the A62-1 plants grafted onto A62-2 plants, little allantoin was accumulated and the concentrations of various components were similar to those of the ungrafted intact A62-2 plants.

A62-1 and A62-2 plants not inoculated with Rhizobium showed approximately the same levels of allantoin and of other components when the same concentration of Ncompounds was supplied. With a late inoculation, A62-1 plants showed a delayed accumulation of allantoin in accordance with the delayed development of nodules.

When nodulated soygean plants were denodulated, the allantoin concentration in the stems and roots rapidly decreased. Addition of ammonia, urea, or nitrate to the denodulated plants retarded the decrease of allantoin concentration in the stems, but maintained the soluble Kjeldahl-N and amino-N concentrations at the same levels as those in nodulated plants. In contrast, addition of any one to nodulated plants did not increase the allantoin accumulation.
