Summary

Two Rhizobium strains were studied for their chemotaxis, nodulation, nitrogenase activity and other endosymbiotic N2-fixing characteristics with two genotypes of Cicer arietinum. Root exudates were found to attract Rhizobium strains. Nodule-specific root proteins (nodulins) and leghaemoglobin were found to be host-range specific between two strains of Cicer Rhizobium. Physiologically active iron content was more important for nodule functioning than total iron concentration of nodules.
