Ecological factors and adaptive processes in N2-fixing bacterial populations of the plant environmenA third mechanism is possible in which ‘pre-adapted’ genes are maintained in soil populations at very low frequencies and energy costs, and whose transfer is triggered by the selective factor to which they constitute an adaptation.

Nitrogen fixation associated with roots of Kallar grass (, L. Kunth) very high and photosynthetic activity is reasonably good. N.-fixing bacteria were counted on the same samples by plate count and MPN methods, the latter being estimated on the basis of ARA and pellicle formation. Fairly high numbers of bacteria (10.–10.) were recorded in the histoplane fraction whi

Population dynamics of , and its bacteriophage in soillying host cells and exhibit a 1000-fold increase in number. Phage required a host cell population of at least 100–1000 per g of soil in order to multiply. The phage burst detected under these conditions increased as the cell to phage ratio increased. Long term incubation studies showed that the act
