Nitrogen (N) fixation through legume-Rhizobium symbiosis is important for enhancing agricultural productivity and is therefore of great economic interest. Growing evidence indicates that other soil beneficial bacteria can positively affect symbiotic performance of rhizobia. Nodule endophytic plant growth promoting rhizobacteria (PGPR) were isolated from common bean nodules from Nakuru County in...
Soybean (Glycine max [L.] Merr.) is an economically important oilseed crop with annual increase in growing grain demand. a moderately salt-tolerant crop; however, salt stress conditions can affect its growth and yield-related traits and, eventually, reduce productivity. In saline soils, one of the techniques to soybean productivity use rhizobia inoculation. Although, using industrial rhizobia-b...
The rhizobia comprise a diverse group of organisms that elicit hypertrophic growth on the roots of legume plants to form a new organ, the root nodule, which they inhabit to fix nitrogen. This endosymbiotic association makes legume plants autotrophic for external nitrogen, an essential nutrient for plant growth. Because the interaction with rhizobia is highly beneficial, legume plants have evolv...
A putative Ca2+ and calmodulin-dependent protein kinase required for bacterial and fungal symbioses.
Legumes can enter into symbiotic relationships with both nitrogen-fixing bacteria (rhizobia) and mycorrhizal fungi. Nodulation by rhizobia results from a signal transduction pathway induced in legume roots by rhizobial Nod factors. DMI3, a Medicago truncatula gene that acts immediately downstream of calcium spiking in this signaling pathway and is required for both nodulation and mycorrhizal in...
The symbiosis between plants and nitrogen-fixing bacteria is widespread among legumes actinorhizal within the root nodule (NFN) clade. However, there are major differences, as well similarities, in symbioses Frankia those of their associated rhizobia. This review provides an overview NFN symbioses. We outline evolution biogeography compare contrast microsymbionts symbiotic processes. Within cla...
It has already been reported that several strains of different species of rhizobia are capable to degrade the phenolic compounds catechol, p-hydroxybenzoic, salicylic, and protocatechiuc acids (HUSSEIN et al. 1974). GUPTA and AGGRAWAL (1973) also reported the degradation of vanillin by some strains of rhizobia. However, nothing was published about the ability of bacteroids to degrade such compo...
abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...
