A Nitrogen Fixation: The Story of the Frankia Symbiosis
a large input of energy and can occur either biologically, within the cells of various bacteria, or chemically, in fertilizer factories or during lightning storms. Among all living organisms, only bacteria have evolved the complex biochemical mechanisms required for nitrogen fixation. All "higher" plants and animals that are said to fix nitrogen are really only the symbiotic partners of the bac...
متن کاملEvolutionary Dynamics of Nitrogen Fixation in the Legume–Rhizobia Symbiosis
The stabilization of host-symbiont mutualism against the emergence of parasitic individuals is pivotal to the evolution of cooperation. One of the most famous symbioses occurs between legumes and their colonizing rhizobia, in which rhizobia extract nutrients (or benefits) from legume plants while supplying them with nitrogen resources produced by nitrogen fixation (or costs). Natural environmen...
متن کاملSymbiosis between Chlorella Sp. and Azotobacter Chroococcum and Nitrogen Fixation
Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...
متن کاملPotential for Nitrogen Fixation in the Fungus-Growing Termite Symbiosis
Termites host a gut microbiota of diverse and essential symbionts that enable specialization on dead plant material; an abundant, but nutritionally imbalanced food source. To supplement the severe shortage of dietary nitrogen (N), some termite species make use of diazotrophic bacteria to fix atmospheric nitrogen (N2). Fungus-growing termites (subfamily Macrotermitinae) host a fungal exosymbiont...
متن کاملNitrogen Fixation by Ceanothus.
The rapidity of successioni of Ceanothus species in burned-over areas where they are indigenous and the apparent enhancing effect which these species have on the development of other shrubs and ground cover suggests that Ceanothus has a soil-improvement effect and implies the fixation of nitrogen. Nodulation of some species of Ceanothus was observed as early as 1912 (3). Bottomley and also Petr...
