| Abstract: | Actinobacteria of the genus Frankia are able to form a symbiosis with plant roots able to fix nitrogen. The actinorhizal plant Discaria trinervis was co‐inoculated with Frankia ‐strain BCU 110501 and in additon with a helper streptomycete, Micromonospora ‐strain BCRU‐MM18 and grown for 12 weeks. The root nodules are easily visible by the naked eye. In the current issue this symbiotic interaction of gram‐positive bacteria and plant roots is described in more detail (Foto: Gernot Vobis, San Carlos de Bariloche, Argentina).
