  abstract = {{A}ctinorhizal plants are capable of high rates of nitrogen fixation, due to their capacity to establish a root-nodule symbiosis with {N}-2-fixing actinomycetes of the genus {F}rankia. {N}odulation is an ontogenic process which requires a sequence of highly coordinated events. {O}ne of these mechanisms is the induction of defense-related events, whose precise role during nodulation is largely unknown. {I}n order to contribute to the clarification of the involvement of defense-related genes during actinorhizal root-nodule symbiosis, we have analysed the differential expression of several genes with putative defense-related functions in {C}asuarina glauca nodules versus non-inoculated roots. {F}our genes encoding a chitinase ({C}g{C}hi1), a glutathione {S}-transferase ({C}g{G}st), a hairpin-inducible protein ({C}g{H}in1) and a peroxidase ({C}g{P}ox4) were found to be up-regulated in mature nodules compared to roots. {I}n order to find out to which extend were the encoded proteins involved in nodule protection, development or both, gene regulation studies in response to {SA} and wounding as well as phylogenetic analysis of the protein sequences were performed. {T}hese were further characterized through expression studies after {SA}-treatment and wounding, and by phylogenetic analysis. {W}e suggest that {C}g{C}hi1 and {C}g{G}st are involved in defense or microsymbiont control and {C}g{P}ox4 is involved in nodule development. {F}or {C}g{H}in1 the question "defense, development or both" remains open.},
