Symbiotic (class 11) hemoglobins play a role in oxygen supply to intracellular nitrogen-fixing symbionts in legume root nodules, and in one case (Parasponia sp.), a non-symbiotic (class 1) hemoglobin has been recruited for this function. Here we report the induction of a host gene, dgtrHb1, encoding a truncated hemoglobin in Frankia-induced nodules of the actinorhizal plant Datisca glomerata. Induction takes place specifically in cells infected by the microsymbiont, prior to the onset of bacterial nitrogen fixation. A bacterial gene (Frankia trHbO) encoding a truncated hemoglobin with O-2-binding kinetics suitable for the facilitation Of 02 diffusion (Tjepkema et al., 2002) is also expressed in symbiosis. Nodule oximetry confirms the presence of a molecule that binds oxygen reversibly in D. glomerata nodules, but indicates a low overall hemoglobin concentration suggesting a local function. Frankia TrHbO is likely to be responsible for this activity. The function of the D. glomerata truncated hemoglobin is unknown; a possible role in nitric oxide detoxification is suggested."],["dc.identifier.doi","10.1055/s-2007-965258"],["dc.identifier.isi","000251545400011"],["dc.identifier.pmid","17682965"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/50266"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Blackwell Publishing"],["dc.relation.issn","1435-8603"],["dc.title","Truncated hemoglobins in actinorhizal nodules of Datisca glomerata"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
