rattlesnake plant root nodules

Because the number of root nodules of both low R/FR-grown MG20 plants and white light-grown phyB mutants declined, we hypothesized that the observed reduction in root nodule number should be controlled by the same mechanism in both plant genotypes and furthermore, that it would be mediated by phyB. Were those nematodes? In the root nodules in the medium size group (1.5− 2.0 mm in diameter), nitrogen-fi xing activity per unit fresh weight of nodule was highest at the fl owering stage and rapidly decreased thereafter.

Observation of a cut root nodule If a root nodule is cut open and the inside is pink/red the nodule is active and fixing lots of nitrogen for the plant. Are the nodules on the roots nematodes?
