    Notes: This note presents designs for two inexpensive, magnetic circulating pumps. The first pump is designed for corrosive fluids over wide ranges of temperature, to 700 K, and pressure, to 200 MPa, and for flow rates to 6 cm3/s. The second pump is designed primarily for gases at temperatures to 500 K, pressures from 6 kPa to 20 MPa, and flow rates to 60 cm3/s. Each pump consists of a simple cylinder and piston with a central flow channel and gate operated by sample inertia.

    Notes: Hexaploid Tritordeum (×Tritordeum Ascherson et Graebner) has been analyzed by SDS-PAGE, to test the efficiency of the method for confirming the parents of different lines, and for unequivocally discriminating between the lines. The results clearly show that endosperm storage proteins from both parents (durum wheat ——Triticum turgidum conv. durum Desf. em. M.K. —— and Hordeum chilense Roem. et Schulz.) are expressed in the endosperm of the amphiploid between them. Although the spectra of proteins from the parental species overlap on the gel, there are sufficient number of bands with distinct electrophoretic mobilities to identify unambiguously their parental origin. Furthermore, in the six lines of tritordeum analyzed, obtained from crosses between three accessions of H. chilense and four cultivars or lines of wheat, there was sufficient polymorphism amongst the parents, particularly amongst the H. chilense accessions, to enable both aims of the project to be met, that is, to confirm the genealogy of each tritordeum, and to discriminate between different lines. This study provides the basis of future investigation on the relationship between bread-making quality in tritordeum and the allelic composition of storage proteins.

    Androgenesis from a Lolium multiflorum × Festuca arundinacea hybrid to generate extreme variation for freezing-tolerance (1999)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: New opportunities for plant breeding using androgenesis in Lolium × Festuca hybrids have been identified. Plants derived by anther culture from a Lolium multiflorum × Festuca arundinacea (5x) hybrid were screened for freezing-tolerance, and their post-freezing recovery compared. The androgenic population showed extreme diversity in freezing-tolerance. While the majority of androgenic plants had inferior freezing-tolerance compared with the freezing-sensitive L. multiflorum parent, 6% of the population were more freezing resistant than the freezing-tolerant Festuca parent. Novel Lolium and Festuca gene combinations resulting from rare meiotic events were recovered within the androgenic population. The two most freezing-tolerant androgenic plants carried virtually the entire F. pratensis subgenome of F. arundinacea. F. pratensis is known to carry genes for freezing-tolerance and would be expected to be the primary source of genes governing this trait within the F. arundinacea genome. The most freezing-tolerant androgenic plants were more freezing-tolerant than the hybrid plant from which they were derived. Consequently, androgenesis was also effective in removing factor(s) reducing the expression of freezing-tolerance within the L. multiflorum × F. arundinacea (5x) hybrid.

    Microwave apparatus for phase transition studies of corrosive fluids to 1.7 kbar and 588 K (1985)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 56 (1985), S. 1907-1912 
    Details

    Notes: A microwave apparatus for phase boundary determinations of corrosive fluid mixtures to 1.7 kbar and 588 K is described. The apparatus measures shifts in a static microwave energy field caused by changes in sample dielectric properties. The measured interactions involve the entire sample cell; sample volumes are small (∼25 cm3); phase transitions are measured directly. Details of the microwave apparatus and the microwave technique are discussed. Data are presented for pure fluids and for an acid-gas/heavy oil mixture that demonstrate the performance of the apparatus.

    The HMW Glutenin Subunit and Gliadin Compositions of German-Grown Wheat Varieties and their Relationship with Bread-Making Quality (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 103 (1989), S. 0 
    Details
    ISSN: 1439-0523

    Notes: The HMW glutenin subunit and gliadin compositions of 57 German-grown varieties of wheat were determined by 1D- and 2D-polyacrylamide gel electrophoresis, respectively. A Glu-1 quality score was calculated for each variety based on previously observed associations between individual HMW glutenin subuints and SDS-sedimentation volume. The results indicated that approximately 30% of the variation in bread-making quality of the varieties was accounted for by variation in the Glu-1 quality score, and that this proportion was raised to 54 % if the presence or absence of chromosome 1BL.1RS was taken into account. It was also shown that allelic variation at the Gli-1 and Gli-2 loci had a relatively minor effect on quality; indeed, the only significant effect was associated with variation at Glu-1, and the influence of this locus was principally due to the deterimental effect of 1BL.1RS.

    Dosage effects of chromosomes of homoeologous groups 1 and 6 upon bread-making quality in hexaploid wheat (1990)
    Springer
    Theoretical and applied genetics 80 (1990), S. 281-287

    Notes: Summary The endosperm storage proteins, glutenin and gliadin, are major determinants of bread-making quality in hexaploid wheat. Genes encoding them are located on chromosomes of homoeologous groups 1 and 6. Aneuploid lines of these groups in spring wheat cultivar ‘Chinese Spring’ have been used to investigate the effect of varying the dosage of chromosomes and chromosome arms upon bread-making quality, where quality has been assessed using the SDS-sedimentation test. Differences between the group 1 chromosomes for quality were greater than those between the group 6 chromosomes. The chromosomes were ranked within homoeologous groups for their effect on quality as follows (〉=better quality): 1D〉1B〉1A and 6A〉6B=6D. The relationship of chromosome dosage with quality was principally linear for four of the chromosomes, but not for 6B and 6D. Increases in the dosage of 1B, 6A and, especially, 1D, were associated with significant improvements in quality, whereas increases in the dosage of 1A were associated with reductions in quality. The effects of 1A and 1D were such that the best genotype for quality was nullisomic 1A-tetrasomic 1D. For group 1, effects of the long arm appeared in general to be more important than effects of the short arm. For group 6, effects were found associated with the long arms as well as with the short arms, a surprising result in view of the absence of genes encoding storage proteins on the long arms. Significant interactions were found between chromosomes and genetic backgrounds, and between individual chromosomes. Analysis of trials grown over two years demonstrated that, although additive environmental differences over years and genotype x years interaction were present, they were relatively small in magnitude compared with purely genetic differences.

    RFLP-based genetic map of rye (Secale cereale L.) chromosome 1R (1991)
    Springer

    ISSN: 1432-2242
    Keywords: Rye ; Genetic mapping ; RFLP ; Storage protein ; Isozyme
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A map of chromosome 1R of rye was constructed using 16 molecular and biochemical loci. From long arm to short arm, known-function loci were placed in the order: XAdh — XLee — Glu-R1[Sec-3] — XPpdk-1R — XEm-1R-1 — XEm-1R-2 — Centromere — XNor-R1 —Gpi-R1 — XGli-R1 [Sec-1a] along with six anonymous genomic and cDNA clones from wheat. The map, which spans 106 cM with 12 loci clustered in a 15-cM region around the centromere, shows reasonably good agreement with previously published maps for the centromeric region, whereas the XNor-R1 — Gpi-R1 region gives a much larger distance than previously reported.

    Genomic in situ hybridization to identify alien chromosomes and chromosome segments in wheat (1992)
    Springer
    Theoretical and applied genetics 84 (1992), S. 778-786 
    Details
    ISSN: 1432-2242
    Keywords: Genomic probing ; In situ hybridization ; Interphase cytogenetics ; Physical mapping ; Triticum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Genomic in situ hybridization was used to identify alien chromatin in chromosome spreads of wheat, Triticum aestivum L., lines incorporating chromosomes from Leymus multicaulis (Kar. and Kir.) Tzvelev and Thinopyrum bessarabicum (Savul. and Rayss) Löve, and chromosome arms from Hordeum chilense Roem. and Schult, H. vulgare L. and Secale cereale L. Total genomic DNA from the introgressed alien species was used as a probe, together with excess amounts of unlabelled blocking DNA from wheat, for DNA:DNA in-situ hybridization. The method labelled the alien chromatin yellow-green, while the wheat chromosomes showed only the orange-red fluorescence of the DNA counterstain. Nuclei were screened from seedling root-tips (including those from half-grains) and anther wall tissue. The genomic probing method identified alien chromosomes and chromosome arms and allowed counting in nuclei at all stages of the cell cycle, so complete metaphases were not needed. At prophase or interphase, two labelled domains were visible in most nuclei from disomic lines, while only one labelled domain was visible in monosomic lines. At metaphase, direct visualization of the morphology of the alien chromosome or chromosome segment was possible and allowed identification of the relationship of the alien chromatin to the wheat chromosomes. The genomic in-situ hybridization method is fast, sensitive, accurate and informative. Hence it is likely to be of great value for both cytogenetic analysis and in plant breeding programmes.
