dc.descriptionExplants of immature soybean (Glycine max) fruits were cultured with different N sources (glutamine, asparagine and allantoin) and the distribution of N determined in the different parts of the explant. All three sources of N were equally efficient for protein accumulation in the cotyledons. This gain in N was not the result of mobilization of N from other parts of the explant. Mobilization did occur in the N-free control, where the ureide fractions were preferentially mobilized from the stem and pod-wall. Allantoin promoted an increase in protein of the stem sections, similar to the amides, while allantoin was more efficient than the amides in retarding N mobilization from the pod-walls. It is suggested that ureides are metabolized in stems and pod-walls. The amino acid composition of the soluble N pool showed highly characteristic patterns for the different explant tissues, independent of the N source. The metabolic adjustments made in different parts of the soybean fruit explant in response to the N source used, appear to be efficient in maintaining an adequate supply of amino acids for reserve protein synthesis in the developing seeds.
