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.作者: 責(zé)問 時間: 2025-3-22 09:56
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.

J. J. Germida and their kinetic energy term in a Lagrangian are largely “dictated” by the local internal symmetry. It is shown how the Klein-Noether identities fix the action for any Yang-Mills theory (with mild conditions on the symmetry group). Field equations for higher-spin fields are mentioned.

W. D. P. Stewart,P. Rowelllds (photon, intermediate bosons, gluons, etc.) come out on at least formally equal footings as gauge fields. At this stage there remains still an essential difference between them and the matter fields of leptons and quarks. The introduction of supersymmetry can help to eliminate this difference.
