Background and Aims: Supernumerary B chromosomes (Bs) represent a specific type of selfish genetic element. As Bs are dispensable for normal growth, it is expected to observe B polymorphisms among populations. To address whether Bs maintained in geographically distinct populations of cultivated and weedy rye are polymorphic, the distribution patterns and the transcriptional activity of differe…
A novel two-step route for the synthesis of RhFe3N is presented that yields the target material with a significantly improved phase purity. Except from Fe0.5Rh0.5, the absence of other side products is exemplified on the basis of powder XRD, REM/EDX measurements, and Mo¨ssbauer investigations. As predicted from density-functional theory calculations, both Rietveld refinement and Mo¨ssbauer…
