  abstract = {{S}ymbiotic nitrogen-fixing associations between {C}asuarina trees and the actinobacteria {F}rankia are widely used in agroforestry in particular for salinized land reclamation. {T}he aim of this study was to analyze the effects of salinity on the establishment of the actinorhizal symbiosis between {C}. glauca and two contrasting {F}rankia strains (salt sensitive; {C}cl3 vs. salt tolerant; {C}e{D}) and the role of these isolates in the salt tolerance of {C}. glauca and {C}. equisetifolia plants. {W}e show that the number of root nodules decreased with increasing salinity levels in both plants inoculated with {C}cl3 and {C}e{D}. {N}odule formation did not occur in seedlings inoculated with {C}cl3 and {C}e{D}, at {N}a{C}l concentrations above 100 and 200 m{M}, respectively. {S}alinity also affected the early deformation of plant root hairs and reduced their number and size. {I}n addition, expression of symbiotic marker {C}g12 gene, which codes for a subtilase, was reduced at 50 m{M} {N}a{C}l. {T}hese data suggest that the reduction of nodulation in {C}. glauca under salt stress is in part due to inhibition of early mechanisms of infection. {W}e also show that prior inoculation of {C}. glauca and {C}. equisetifolia with {F}rankia strains {C}cl3 and {C}e{D} significantly improved plant height, dry biomass, chlorophyll and proline contents at all levels of salinity tested, depending on the {C}asuarina-{F}rankia association. {T}here was no correlation between in vitro salt tolerance of {F}rankia strains and efficiency in planta under salt stressed conditions. {O}ur results strongly indicate that increased {N} nutrition, photosynthesis potential and proline accumulation are important factors responsible for salt tolerance of nodulated {C}. glauca and {C}. equisetifolia.},
