Symbiotic characterization and diversity of rhizobia associated with native and introduced acacias in arid and semi-arid regions in Algeria.
The diversity of rhizobia associated with introduced and native Acacia species in Algeria was investigated from soil samples collected across seven districts distributed in arid and semi-arid zones and Acacia saligna appeared as the most promiscuous host because it was efficiently nodulated with the widest diversity ofrhizobia taxa.
Nitrogen fixation (C2H2 reduction) by Medicago nodules and bacteroids under sodium chloride stress
The nitrogen fixation capacity of the M. ciliaris-Rhizobium meliloti (ABS7) symbiosis under saline conditions leads us to recommend the introduction of this association in salt-troubled areas.
Two Sinorhizobium meliloti glutaredoxins regulate iron metabolism and symbiotic bacteroid differentiation.
Two S. meliloti Grx proteins are essential for symbiotic nitrogen fixation, playing independent roles in bacterial differentiation and the regulation of iron metabolism.
Multilocus sequence analysis of root nodule isolates from Lotus arabicus (Senegal), Lotus creticus, Argyrolobium uniflorum and Medicago sativa (Tunisia) and description of Ensifer numidicus sp. nov.
Nine isolates from Argyrolobium uniflorum, Lotus creticus, Medicago sativa and Lotus arabicus were analysed by multilocus sequence analysis (MLSA) and clusters A and C are suggested as representing two novel species within the genus Ensifer.
Antimicrobial activities of Rhizobium sp strains against Pseudomonas savastanoi , the agent responsible for the olive knot disease in Algeria
In the present investigation, six Rhizobium strains isolated from Algerian soil were checked for their antimicrobial activity against Pseudomonas savastanoi, the agent responsible for olive knot
Distribution of Medicago Species and Their Microsymbionts in a Saline Region of Algeria
Tolerance to salinity, of both bacterial and plant partners, was studied under laboratory conditions, showing that plants are susceptible to NaCl concentrations of 50 mM, 15-fold lower than that of their associated rhizobia (800 mM).
Nodular bacterial endophyte diversity associated with native Acacia spp. in desert region of Algeria
Five species of Acacia indigenous to Tamanrasset (Algeria) showed the highest nodulation ability across the different sites in this region, indicating the widespread occurrence of compatible rhizobia in the soils, and a strong tolerance profile to salinity and high temperature was revealed.
Rhizobial diversity associated with the spontaneous legume Genista saharae in the northeastern Algerian Sahara
This study is the first report on the characterization of G. saharae microsymbionts in the Algerian Sahara using phenotypic and phylogenetic characterization.
Mycorrhizal colonization decreases respiration of common bean nodulated root in hydroaeroponic culture
The tripartite inoculation improved growth parameters under severe P-deficiency with a decrease in nodulated root O2 consumption and increased the growth of all plant organs and the nodulation with a large genotypic variability.
Impact of single and co-inoculations with Rhizobial and PGPR isolates on chickpea (Cicer arietinum) in cereal-growing zone soil
Findings emphasized inoculation on native soils at a little scale before large assays on field because no one could predict inocula behavior with native soil microflora.
