“…Inoculation with these local rhizobia strains, especially RhM11, could play a crucial role in plant growth and nodule biomass improvement under salinity constraint when plant growth depends on SNF. This finding agrees with those of our recent studies where the same strains have been tested under P deficiency and revealed a marked increase both in nodule acid phosphatase activity (Mandri et al 2011) and nodule O 2 permeability (Bargaz et al 2011a, b). Under the saline treatment symbiotic nitrogen fixation was not significantly affected in CIAT899-Paulista, CIAT899-Efequince and RhM11-Paulista in comparison with the remaining combinations ( Figs.…”

This study compared growth, nodulation, nitrogen fixation, and nodular enzyme activities in response to salinity in some common bean-rhizobia symbiotic combinations. Seeds of Paulista and Efequince, two varieties of the common bean (Phaseolus vulgaris) were germinated and seedlings were transferred to pots containing vermiculite inoculated with the reference Rhizobium strain CIAT899 or with RhM11 or RhM14, two local strains. Plants were grown in a temperature-controlled glasshouse at 28°C and irrigated with a nutrient solution without NaCl (control) or supplemented with 25 mM NaCl (stressed). Plants were harvested at the flowering stage. The results showed that in controls, inoculation with RhM11 improved plant and nodule growth compared with those inoculated with RhM14 and CIAT 899. NaCl treatment generally had a negative affect on plant and nodule growth. Under the saline treatment, symbiotic nitrogen fixation was not significantly affected in the CIAT899-Paulista, CIAT899-Efequince and RhM11-Paulista combinations. Plant mineral nutrition was negatively affected under salt treatment for all of the tested symbiotic combinations. Inoculation with CIAT899 and RhM11 conferred more plant tolerance to salinity than inoculation with RhM14. The nodular phosphoenolpyruvate carboxylase (PEPC) and malate dehydrogenase (MDH) exhibited higher activities and were less affected by salinity in plants inoculated with the reference strain CIAT899 than those inoculated with local strains. We conclude that plants inoculated with CIAT899 and RhM11 showed more salinity stress tolerance than those inoculated with RhM14.

“…RhM 11 had been isolated from nodules of common bean plants collected from a farmer's fields in the Haouz area of Marrakesh, Morocco. The common bean plants inoculated with this local rhizobial strain showed a higher nodulation and an increase in phytase and phosphatase activities in nodules under P deficiency (Mandri et al 2011).…”

Although recent studies have addressed the effects of phosphorus (P) deficiency on nodule O 2 permeability, little attention has been given to the relationship between nodule P status and nodule permeability. To study these traits, four recombinant inbred lines, namely RILs 34, 83, 115, 147 and one local variety (Concesa) of common bean (Phaseolus vulgaris) were inoculated with RhM11 (a native rhizobial strain from Haouz area of Marrakesh), and grown in hydroaeroponic culture under Psufficiency (250 μmol P plant −1 week −1 ) versus P-deficiency (75 μmol P plant −1 week −1 ) conditions. At the flowering stage, the biomass of plants and nodules and their P contents was determined after measuring O 2 uptake by nodulated roots (Conr) and nodule conductance to O 2 diffusion (g n ).The results showed that P-deficiency significantly decreased plant growth and nodulation, though there were differences between bean genotypes. P-deficiency also induced a decrease in nodule P content (31%) in both sensitive (83, 147) and tolerant lines (34, 115), a 42 and 27% reduction in shoots of sensitive and tolerant lines, respectively. These decreases were associated with significant variations in nodule surface and O 2 permeability among bean genotypes and P-nutrition. Under P-deficiency, g n increased more for the sensitive (39%) than for the tolerant lines (27%). This increase was linked with a rise both in the P levels in nodules and shoots, as well as in the efficiency of symbiotic nitrogen fixation as determined by nodule-dependent biomass production for the sensitive lines. Furthermore, positive correlations were found between O 2 permeability, g n and P content both in nodules and shoots (r 2 =0.94** and r 2 =0.96**). We conclude that nodule variations in Conr and g n are related to nodule P content, and may contribute to the adaptation of energy metabolism in N 2 -fixing bean nodules to P-deficiency.
