Cross-Reaction of Predominant Nitrogen-Fixing Bacteria with Enveloped Round Bodies in the Root Interior of Kallar Grass

摘要

Diazotrophic rods occurring in high numbers (about 10⁸ rods per g [dry weight] of root) in the root interior of Kallar grass were localized by indirect immunofluorescence in cross sections of the same roots. Specifically stained round bodies which were apparently covered by a nonantigenic envelope were found in the aerenchymatic tissue.
