1. Whole cells of Methylomonas Pl1 contained ubiquinone, identified as ubiquinone-8. No naphthaquinone was detected. Ubiquinone was located predominantly in the particulate fraction, which also contained most of the NADH oxidase activity. 2. Aerobic incubation of cells with formaldehyde or methanol resulted in about 20% reduction of ubiquinone, irrespective of the presence or absence of dinitro...

Paramutations represent heritable epigenetic alterations that cause departures from Mendelian inheritance. While the mechanism responsible is largely unknown, recent results in both mouse and maize suggest paramutations are correlated with RNA molecules capable of affecting changes in gene expression patterns. In maize, multiple required to maintain repression (rmr) loci stabilize these paramut...

We have recently described a new method, primed LD typing or PLT, for specific identification of HLA-D antigens. Highly discriminatory PLT cells have been developed which clearly differentiate between cells of individuals that restimulate strongly and those that restimulate weakly. Seven such discriminatory PLT cells have been used to define three antigens called PL1, PL2, and PL3; two more PLT...

This paper describes an existing tool set being used in the German speaking market for reengineering and migration projects. The tool set with the name SOFTREORG runs under MS-Windows on a PC-Workstation and supports the auditing, reverse engineering, reengineering and retesting of COBOL, PL1 and Assembler Programs in connection with the corresponding MICRO FOCUS workbench. This reengineering w...

BACKGROUND Wood cell walls are rich in cellulose, hemicellulose and lignin. Hence, they are important sources of renewable biomass for producing energy and green chemicals. However, extracting desired constituents from wood efficiently poses significant challenges because these polymers are highly cross-linked in cell walls and are not easily accessible to enzymes and chemicals. RESULTS We sh...

R2R3 Myb genes are widely distributed in the higher plants and comprise one of the largest known families of regulatory proteins. Here, we provide an evolutionary framework that helps explain the origin of the plant-specific R2R3 Myb genes from widely distributed R1R2R3 Myb genes, through a series of well-established steps. To understand the routes of sequence divergence that followed Myb gene ...
