Site of natural 15N [Nitrogen] enrichment of soybean nodules [Glycine max, Rhizobium japonicum]

Site of natural 15N [Nitrogen] enrichment of soybean nodules [Glycine max, Rhizobium japonicum]

Soybean (Glycine max L. Merrill) nodules are usually more enriched in 15N than other tissues. We show that both bacteroids and nodule cortex are considerably more enriched in 15N than nodule cytosol, with bacteroids being slightly more enriched than the cortex. Hence, 15N enrichment occurs in cells...

Zusammenfassung:Soybean (Glycine max L. Merrill) nodules are usually more enriched in 15N than other tissues. We show that both bacteroids and nodule cortex are considerably more enriched in 15N than nodule cytosol, with bacteroids being slightly more enriched than the cortex. Hence, 15N enrichment occurs in cells of both plant and bacterial origin.
