Abstract A virus (RL 1) that infects Rhizobium leguminosarum was isolated and studied. The virus has phagelike morphology; it has a hexagonal head and a long, flexible, noncontractile tail with a baseplate. The edgeto-edge diameter of head is 760 Å. The tail is 1515 Å long and 115 Å wide. RL 1 is stable at 4° C in distilled water, with only 20% loss in the titer after one month storage. It does not require any ion for stability, and is stable between pH 6.0 and 8.0. The virus is composed of two components; one is thermal sensitive and the other is relatively thermal resistant. Adsorption and ‘one step growth’ experiments under normal growth conditions showed a slow adsorption rate (0.82×10-9 cm3 min-1) followed by a 90 min latent period. The burst size was approximately 100 virus particles per cell.
