Abstract
Highly purified soybean lectin (SBL) was labeled with fluorescein isothiocyanate (FITC-SBL) or tritium (3H-SBL) and repurified by affinity chromatography. FITC-SBL was found to bind to living cells of 15 of the 22 Rhizobium japonicum strains tested. The lectin did not bind to cells of the other seven R. japonicum strains, or to cells of any of the nine Rhizobium strains tested which do not nodulate soybean. The binding of the lectin to the SBL-positive strains of R. japonicum was shown to be specific and reversible by hapten inhibition with d-galactose or N-acetyl-d-galactosamine.Keywords
