SUMMARY: Excised soybean root nodules exposed to an atmosphere containing an excess of 15N2 incorporated the label first into the centrifugal fraction containing the intracellular membrane envelopes and small amounts of bacteroid cell walls. The 15N concentration then increased in the soluble portion of the nodules. The bacteroid fraction was not labelled after 2 hr. exposure of the nodules to 15N2. In ageing nodules incorporation of 15N into the soluble fraction declined before incorporation… CONTINUE READING
