Additional file 2: Figure S1. of Reverse U-to-C editing exceeds C-to-U RNA editing in some ferns – a monilophyte-wide comparison of chloroplast and mitochondrial RNA editing suggests independent evolution of the two processes in both organelles

Comparison of mitochondrial RNA editing sites between monilophytes and lycophytes. The experimentally confirmed editing sites in the genes atp1 and nad5 of the monilophyte species Polypodium cambricum, Dicksonia antarctica and Azolla filiculoides are compared with the respective editing sites deposited in NCBI from the lycophytes Isoetes engelmannii and Selaginella moellendorffii. Only 16 edits are shared between all five taxa. Most of the edits from the two lycophytes are unique to either one species or are shared between the two lycophytes and are therefore most likely independent gains. For the basal lycophyte Phlegmariurus squarrosus only 14 edits (all of the C-to-U type) are found in our cDNA analysis. Three of these edits are shared between all three lycophytes and six between Phlegmariurus and Isoetes. (DOCX 127 kb

Autoindustrie – auf dem richtigen Weg?

Die deutsche Automobilindustrie steht vor gravierenden Problemen: Nach einem langanhaltenden Zuwachs bei Produktion und Export droht sie ihre dominierende Stellung durch die internationalen Handelsstreitigkeiten zu verlieren. Aber auch die Anforderungen durch die europäischen Klimaschutzziele machen einen tiefgreifenden Wandel erforderlich. Dieser bezieht sich nicht allein auf die Produktion von Autos, sondern auch auf die steigende Nachfrage nach Mobilitätsdienstleistungen. Durch Carsharing und eine bessere Verknüpfung von öffentlichem und privatem Verkehr lassen sich die Ziele besser erreichen. Allein durch die Verwendung von neuen Energie- und Antriebsoptionen ist dies wohl nicht möglich. Dennoch bedeuten auch diese einschneidende Veränderungen im Produktions- und Vertriebssystem

Molecular-frame differential photoelectron circular dichroism of O 1s-photoelectrons of trifluoromethyloxirane

The differential photoelectron circular dichroism (PECD) of O 1s photoelectrons of R-trifluoromethyloxirane enantiomers as a function of the photoelectron emission direction in the molecular frame of reference and the direction from which circularly polarized light hits the molecule, is studied experimentally and theoretically for different photoelectron kinetic energies. A coincident detection of the photoelectrons and two ionic molecular fragments, performed with cold target recoil ion momentum spectroscopy, allows us to determine the orientation of the molecule in the laboratory frame and to obtain in addition the molecular-frame photoelectron diffraction patterns. From these we deduce the differential PECD. For given molecular orientations and photoelectron emission directions, we observe a normalized PECD strength clearly beyond 50%. These observations are in agreement with respective relaxed-core Hartree-Fock calculations, performed by employing the single center method. The present results support our recent observation of a huge differential PECD in O 1s photoemission of the methyloxirane molecule

Photoelectron circular dichroism of O 1s-photoelectrons of uniaxially oriented trifluoromethyloxirane: energy dependence and sensitivity to molecular configuration

The photoelectron circular dichroism (PECD) of the O 1s-photoelectrons of trifluoromethyloxirane (TFMOx) is studied experimentally and theoretically for different photoelectron kinetic energies. The experiments were performed employing circularly polarized synchrotron radiation and coincident electron and fragment ion detection using cold target recoil ion momentum spectroscopy. The corresponding calculations were performed by means of the single center method within the relaxed-core Hartree–Fock approximation. We concentrate on the energy dependence of the differential PECD of uniaxially oriented TFMOx molecules, which is accessible through the employed coincident detection. We also compare the results for the differential PECD of TFMOx to those obtained for the equivalent fragmentation channel and similar photoelectron kinetic energy of methyloxirane (MOx), studied in our previous work. Thereby, we investigate the influence of the substitution of the methyl group by the trifluoromethyl group at the chiral center on the molecular chiral response. Finally, the presently obtained angular distribution parameters are compared to those available in the literature
