    Notes: Summary In the presence of ethanol, corticosterone and dexamethasone inhibit choline acetyltransferase and acetylcholinesterase activities in cultured fetal brain cells of the rat. These results suggest that corticosteroids may have an important influence on the activity of cholinergic enzymes in the fetal brain and may antagonize the effects of ethanol in this setting.

    SPLICE SITE SELECTION IN PLANT PRE-mRNA SPLICING (1998)
    Palo Alto, Calif. : Annual Reviews
    Annual Review of Plant Physiology and Plant Molecular Biology 49 (1998), S. 77-95

    Notes: Abstract The purpose of this review is to highlight the unique and common features of splice site selection in plants compared with the better understood yeast and vertebrate systems. A key question in plant splicing is the role of AU sequences and how and at what stage they are involved in spliceosome assembly. Clearly, intronic U- or AU-rich and exonic GC- and AG-rich elements can influence splice site selection and splicing efficiency and are likely to bind proteins. It is becoming clear that splicing of a particular intron depends on a fine balance in the "strength" of the multiple intron signals involved in splice site selection. Individual introns contain varying strengths of signals and what is critical to splicing of one intron may be of less importance to the splicing of another. Thus, small changes to signals may severely disrupt splicing or have little or no effect depending on the overall sequence context of a specific intron/exon organization.

    Notes: Abstract A gamma camera technique for the study of bubble scavenging of surface-active organic materials in seawater is investigated. The technique is shown to be suitable for the quantitative determination of scavenging rates, surface adsorbtion rates and seaair transfer processes. The major drawback to the procedure is the present lack of availability of gamma labelled surface-active materials with representative oceanographic characteristics.

    Radiotracer studies of surfactant transport to the sea-air interface by submillimeter-size bubbles (1991)
    Springer

    Notes: Abstract A radiotracer test system has been developed for laboratory studies to investigate the bubble transport of natural surfactant materials from seawater to the air-water interface. Using this system, we have analyzed the rates at which saturated and unsaturated 14C-labeled fatty acids (stearic and oleic acids, respectively) and triolein, an unsaturated fatty acid triglyceride, are scavenged from seawater by air bubbles at differing airflow rates and bubbling times. The bubble field used was similar in size distribution to that which exists in natural wave or wake-induced turbulence where significant aeration of seawater occurs. We have found in our studies that the scavenging rate for each material is proportional to the bulk water concentration of the material and that the constant of proportionality itself appears approximately proportional to the square root of the airflow rate. We have also found that oleic acid is scavenged more rapidly than stearic acid, which is in turn scavenged more rapidly than triolein. This finding indicates a strong dependence of the scavenging process on the underlying chemical polarity and/or on the stereochemical properties of the material being scavenged.

    Genetic variation in the subunits of globulin-1 storage protein of French bean (1981)

    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)

    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.
