The possibility of differing catabolic enzymes for allantoic acid leading to differences in [N.sub.2] fixation sensitivity to water deficits opens the possibility of genotypic segregation based on ureide degradation characteristics.
Since allantoate amidinohydrolase activity might be associated with [N.sub.2] fixation tolerance to water deficit and response to Mn might be a key point of difference in discriminating between the enzymes for allantoic acid degradation, characterization of the eight tolerant PI lines identified by Sinclair et al.

It has been reported that there are two pathways for the degradation of allantoic acid in soybean leaves.
At 5 wk after transplanting, plants grown at 0, 26.4, 52.8 [micro]M Mn, and half of the plants grown at 6.6 [micro]M Mn were treated by replacing the nutrient solution with 400 mL of nutrient solution containing 5 mM allantoic acid and the respective Mn concentrations.
The ARA for the individual plants treated with ureide were normalized against the mean ARA of those plants grown on 6.6 [micro]M Mn but not treated with allantoic acid. This normalization was done to eliminate variations resulting from changes in the greenhouse environment or plants during the experiment.
