Studies on the white clover -Rhizobium trifolii interaction are the most advanced. Trifoliin A, a lectin present in clover-seedling roots, binds hapten reversibly to carbohydrate antigens cross-reactive on the capsular polysaccharide of R. trifolii and clover epidermal-cells.244 A specific hapten that inhibits binding of trifoliin A to both surfaces is 2-deoxy-D-arabino-hexose.245 It has also been shown that levels of trifoliin A on root hairs decline with increasing concentrations of nitrate, in parallel to root-nodule development,246 and that lectin receptors are transient on R. trifolii, in a way coinciding with its capacity to be adsorbed to clover roots.247...

The semiconservative replication of DNA at the chromosomal level was shown by J. H. Taylor and coworkers. Using autoradiography and bean seedling root cells in tissue culture, they showed that, after a part of a cycle of duplication with [3H]thymidine (a selective label for DNA), the two chromosomes, descended from an original unlabeled chromosome, were both labeled. Following an additional duplication in the absence of labeled thymidine, the labeled chromosome yielded one labeled and one unlabeled descendant, as predicted by the semiconservative mechanism.
