    Notes: Summary Single seeds of over 100 bean cultivars were analyzed by two-dimensional electrophoresis. The cultivars could be classified into eight groups by virtue of their G2/albumin electrophoretic patterns: TG2, SG2, VG2, PrG2, BG2, MG2, PG2, and PiG2, The polypeptide compositions of these types were largely inter-related having particular polypeptides in common. It was possible to correlate the G2/albumin patterns with agglutinating activity of cow and rabbit blood cells as measured by the agglutination ratio (minimum concentration of extract required to agglutinate cow blood cells: minimum concentration of extract required to agglutinate rabbit blood cells). The active lectin polypeptides were identified by extracting lectins from agglutinated erythrocytes and by comparing the qualitative similarities and differences of the G2/albumin patterns and their agglutination activities. A reference catalogue of over 100 bean cultivars giving their phaseolin and G2/albumin electrophoretic patterns, and agglutination ratios is presented.

    Notes: Summary Charge and molecular weight heterogeneity of globulin-1 (G1) polypeptides of the bean, Phaseolus vulgaris L., were revealed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Different bean cultivars were classified into three groups: ‘Tendergreen’, ‘Sanilac’, and ‘Contender’ on the basis of their protein subunit composition. Nine distinct major bands: α51,α49, α48.5,β48T, β48S, β47, γ45.5, γ45S, and γ45C, and two minor bands: γ46T and γ46S were found to account for the three profiles seen on one-dimensional SDS-PAGE. Two-dimensional analysis revealed these eleven protein bands to be composed of a minimum of fourteen distinct protein subunits. The ‘Tendergreen’ and ‘Sanilac’ types differ in their G1 polypeptide composition. The protein patterns of the ‘Contender’ types are intermediate, containing many protein subunits found in the patterns of the ‘Tendergreen’ and ‘Sanilac’ types suggesting a genetic and evolutionary relationship.

    Fractionation of wheat gliadin and glutenin subunits by two-dimensional electrophoresis and the role of group 6 and group 2 chromosomes in gliadin synthesis (1981)
    Springer
    Theoretical and applied genetics 59 (1981), S. 349-359

    ISSN: 1432-2242

    Notes: Summary Subunits of wheat endosperm proteins have been fractionated by two-dimensional electrophoresis. To determine which subunits in the two-dimensional electrophoretic pattern belong to gliadin or glutenin the endosperm proteins have also been fractionated by a modified Osborne procedure and by gel filtration on Sephadex G-100 and Sepharose CL-4B prior to separation by two-dimensional electrophoresis. The control of production of five major grain protein subunits is shown to be determined by chromosomes 6A, 6B and 6D by comparing two-dimensional electrophoretic protein subunit patterns of aneuploid lines of the variety ‘Chinese Spring’. From these and previous studies it is concluded that some α, β and γ gliadins (molecular weights by SDS-PAGE 30,000 to 40,000) are specified by genes on the short arms of homoeologous Group 6 chromosomes, the ω gliadins (molecular weights by SDS-PAGE 50,000 to 70,000) are specified by genes on the short arms of homoeologous Group 1 chromosomes and the glutenin subunits (molecular weights by SDS-PAGE 〉 85,000) are specified by genes on the long arms of homoeologous Group 1 chromosomes. No major gliadins or glutenin subunits were absent when any of the chromosomes in homoeologous Groups 2, 3, 4, 5 or 7 were deleted. However two gliadins whose presumed structural genes are on chromosome 6D were absent in aneuploid stocks of ‘Chinese Spring’ carrying two additional doses of chromosome 2A. Two out of thirty-three intervarietal or interspecific chromosome substitution lines examined, involving homoeologous Group 2 chromosomes, lacked the same two gliadins. All the subunits in the other thirty-one chromosome substitution lines were indistinguishable from those in ‘Chinese Spring’. It is therefore concluded that the major variation affecting gliadin and glutenins in wheat is concentrated on the chromosomes of homoeologous Groups 1 and 6 but Group 2 chromosomes are candidates for further study. An endosperm protein controlled by chromosome 4D in ‘Chinese Spring’ is shown to be a high molecular weight globulin.

    Linkage relationships between genes controlling seed proteins in French bean (1981)
    Springer
    Theoretical and applied genetics 60 (1981), S. 251-259 
    Details
    ISSN: 1432-2242
    Keywords: Phaseolus vulgaris ; Phaseolin ; Seed proteins ; Electrophoresis ; Linkage
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The inheritance of phaseolin and globulin-2 (G2)/albumin polypeptides was investigated in crosses involving varieties which exhibited the three electrophoretic banding patterns of phaseolin found in French bean. ‘Total’ seed protein extracts of single seeds of the F1 and F2 generations from the crosses: ‘Sanilac’ × ‘Contender’, ‘BBL 240’ × ‘Contender’, and ‘Sanilac’ × ‘BBL 240’ were analyzed by two-dimensional electrophoresis. Segregation of the genes controlling phaseolin and G2/albumin polypeptides, and those controlling a further five groups of seed proteins (A, B, D, E, and F) were observed. No recombinant electrophoretic phenotypes were seen for phaseolin or G2/albumin polypeptides suggesting that the genes controlling each of these groups of polypeptides are closely linked and segregate like single Mendelian genes. The phaseolin genes and G2/albumin genes were not linked to each other. The group of genes controlling phaseolin polypeptides were linked to those controlling group B proteins, and those controlling G2/albumin polypeptides were linked to those controlling group F proteins.

    Effects of gamma radiation on two aromatic polysulfones. II. A comparison of irradiation at various temperatures in air-vacuum environmentsPresented in part at the First Chemical Congress of the North American Continent, Mexico City, December 1975. (1979)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The aromatic polysulfone poly(oxy-1,4-phenylenesulfonyl-1,4-phenyleneoxy-1,4-phenyleneiso-propylidene-1,4-phenylene) (I) showed no change in flexural yield strength after doses of γ-radiation up to 600 Mrad in vacuum at 35,80, and 125°C (Tg = 190°C)). However, the flexural strength decreased markedly with doses above 100 Mrad on irradiation in air, to 40-60% of the initial value after 200-400 Mrad, depending on the sample and the irradiation conditions. Chain crosslinking was predominant over scission for irradiation in vacuum at all temperatures; (G(X), G(S), and G(S)/G(X) increased with the irradiation temperature, but G(S)/G(X) decreased to zero above Tg. Poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene) (II) behaved similarly, except that the flexural strength was found to be very dependent on the thermal treatment of the sample. This polymer showed a remarkable retention of its mechanical properties on irradiation up to 200°C (Tg = 230°C) in the absence of air, the flexural strength being retained up to 500 Mrad. Radiation annealing occurred at 35°C in vacuum and air and combined radiation and thermal annealing at 125 and 220°C. Progressive removal of surface layers from flexural test bars of I irradiated in air showed that the decrease in flexural strength with dose could be explained by a decrease in the molecular weight towards the surface resulting from radiation-oxidation reactions.

    Notes: Two aromatic polysulfones, poly(oxy-1,4-phenylenesulfonyl-1,4-phenyleneoxy-1,4-phenyleneisopropylidene-1,4-phenylene) (I) and poly (oxy-1,4-phenylenesulfonyl-1,4-phenylene) (II), undergo crosslinking and chain scission at 30°C during γ-irradiation, the former being predominant in vacuum and the latter in air. Both processes occurred more readily in I, which contains isopropylidene linkages. Gel measurements gave G(crosslink) = 0.051, G(scission) = 0.012 for this polymer at 30°C in vacuum. Increased irradiation temperatures resulted in higher crosslinking and gas yields, especially above the glass transition temperature. The tensile strength, flexural strength, and modulus of I were unaffected by γ-irradiation up to about 50 Mrad in air, but the strength decreased markedly at higher doses. The elongation at break decreased progressively with dose. For both polymers, G(gas) = 0.04 at 30°C with the main products being SO2, H2, CO2, CH4, and H2O.

    Description / Table of Contents: Einfluß von Chlorwasserstoff auf die Korrosion einer FeCrAlY-Legierung in einer simulierten KohlevergasungsatmosphäreEie Chrom-Aluminium-Yttrium-Stahl wurde einer simulierten Kohlevergasungsatmosphäre ausgesetzt die 1000 ppm bzw. 2200 ppm Chlorwasserstoff enthielt und deren Temperatur 450 °C betrug. Durch Erhöhen des Chlorwasserstoffgehalts werden die Reaktionsgeschwindigkeit erhöht und die Mikrostruktur sowie die Zusammensetzung des Korrosionsprodukts beträchtlich verändert. Für diese Ergebnisse werden versuchsweise Mechanismen postuliert, nach denen Metallchloride über die Gasphase transportiert werden.
    Notes: An iron chromium aluminium yttrium steel was exposed to a simulated coal gasifier atmosphere containing 1000 ppm and 2200 ppm hydrogen chloride at 450 °C. Increasing hydrogen chloride content was found to accelerate reaction rates, and significantly alter the microstructure and composition of the corrosion product. Tentative explanations for these results, involving vapour phase transport of metal chlorides are proposed.
