TL;DR: Plant and bacterial antigens contributing to nodule development and symbiosis in pea (Pisum sativum L.) roots were identified after isolation of a set of monoclonal antibody (McAb)-producing hybridoma lines to diversify the range of McAb specificities.

TL;DR: Indole-3-acetic acid is produced in the absence of exogenous tryptophan in all strains but its level is greatly stimulated by applied tryPTophan, and no correlation has been established between the ability to nodulate peas and theAbility to produce IAA.

TL;DR: In conjugational crosses, the transposon insertion associated with both the loss of MAC 281 antigen and the constitutive expression of MAC 203 antigen showed linkage to the chromosomal rif allele, suggesting that the relevant genetic determinants map to genomic sites that are not associated with nifA or any known genes on the symbiotic plasmid.

TL;DR: The development of the nitrogen-fixing legume root nodule involves many forms of cell-to-cell contacts and interactions in the pathway of differentiation, which leads to the differentiation of a variety of different cell types from the same nodule meristem.
