Abstract
- The nitrogen-fixing actinomycete Frankia coexists with actinorhizal plants via nodules and supplies nitrogen compounds to the plants. Although communication has been suggested to exist through chemical substances in this nodule symbiosis, the details underlying this mechanism remain elusive. The biphenyl-type diarylheptanoids (BP-CDHs), alnusonol, and alnusdione, previously isolated from the actinorhizal plant A. sieboldiana branch wood, are secondary metabolites that accumulate in a limited number of plant species. However, since relatively widely distributed in actinorhizal plants, we investigated whether adding A. sieboldiana root extracts and these BP-CDHs could affect plant seedlings inoculated with Frankia. The results showed that the addition of root extract or alnusonol significantly increased the number of nodules and lobes more than two times compared with that upon Frankia supplementation only. We also proved that the extracted components of this plant affected nodule symbiosis. Finally, we confirmed through LC-MS that the root extract component contained BP-CDH, alnusonol. The above-described results indicate that BP-CDHs, at leaset alnusonol, might function as signal compounds from the plant side of the actinorhizal symbiosis between A. sieboldiana and Frankia.
