  abstract = {{A}ctinorhizal plants are able to establish a symbiotic relationship with {F}rankia bacteria leading to the formation of root nodules. {T}he symbiotic interaction starts with the exchange of symbiotic signals in the soil between the plant and the bacteria. {T}his molecular dialog involves signaling molecules that are responsible for the specific recognition of the plant host and its endosymbiont. {H}ere we studied two factors potentially involved in signaling between {F}rankia casuarinae and its actinorhizal host {C}asuarina glauca: (1) the {R}oot {H}air {D}eforming {F}actor ({C}g{RHDF}) detected using a test based on the characteristic deformation of {C}. glauca root hairs inoculated with {F}. casuarinae and (2) a {NIN} activating factor ({C}g{NINA}) which is able to activate the expression of {C}g{NIN}, a symbiotic gene expressed during preinfection stages of root hair development. {W}e showed that {C}g{RHDF} and {C}g{NINA} corresponded to small thermoresistant molecules. {B}oth factors were also hydrophilic and resistant to a chitinase digestion indicating structural differences from rhizobial {N}od factors ({NF}s) or mycorrhizal {M}yc-{LCO}s. {W}e also investigated the presence of {C}g{NINA} and {C}g{RHDF} in 16 {F}rankia strains representative of {F}rankia diversity. {H}igh levels of root hair deformation ({RHD}) and activation of {P}ro{C}g{NIN} were detected for {C}asuarina-infective strains from clade {I}c and closely related strains from clade {I}a unable to nodulate {C}. glauca. {L}ower levels were present for distantly related strains belonging to clade {III}. {N}o {C}g{RHDF} or {C}g{NINA} could be detected for {F}rankia coriariae ({C}lade {II}) or for uninfective strains from clade {IV}.},
