Summary
Lipopolysaccharides (LPS) were extracted from two strains ofRhizobium japonicum (61A76NS and 3I1b110-I). The extracted LPS was purified by gel filtration column chromatography and the amount of 2-keto-3-deoxyoctonate (KDO) was determined. Column purified LPS from both strains were conjugated to rhodamine isothiocyanate on celite to examine binding of this purified, labeled surface component to aseptically grownGlycine soja (wild soybean) seedlings as a basis for symbiotic specificity using fluorescent microscopy. Rhodamine conjugated LPS from both strains ofRhizobium japonicum did not exhibit specific binding to wild soybean seedling roots.
