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"]]

Arabidopsis root colonization by P. indica was examined in sterile culture on the medium of Murashige and Skoog. P. indica formed intracellular structures in Arabidopsis root epidermal cells and caused changes in root growth, leading to stunted and highly branched root systems. This effect was because of a diffusible factor and could be mimicked by IAA. In addition, P. indica was shown to produce IAA in liquid culture. We suggest that auxin production affecting root growth is responsible for, or at least contributes to, the beneficial effect of P. indica on its host plants."],["dc.identifier.doi","10.1111/j.1399-3054.2007.00983.x"],["dc.identifier.isi","000250763500006"],["dc.identifier.pmid","18251849"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/48657"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Blackwell Publishing"],["dc.relation.issn","0031-9317"],["dc.title","Piriformospora indica affects plant growth by auxin production"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
